When it comes to outdoor living, most homeowners look for comfort, convenient and design as well as the durability of a product. Cast aluminum patio furniture has made many inroads as the material of choice of many people when furnishing their outdoor living space.

The method with which cast aluminum patio furniture is manufactured allows it to have intricate designs as well as strength. A wooden pattern is first designed to represent the item being made. Once it is completed, it is pressed into a sand mold, which leaves the exact impression of the item. This can include very intricate designs, which will also be pressed into the sand mold.

Molten aluminum is then poured into the mold creating an exact replica of the wooden mold pressed into the sand. Once the aluminum cools and hardens the sand is knocked away and the piece is finished as necessary by sanding and painting. The cast aluminum patio furniture can be left on the patio throughout the winter since aluminum is known for its ability to stand up to the elements.

Iron Rapidly Falling From Grace

For many years cast iron and wrought iron were the metals of choice for outdoor furniture but both are now being passed up as cast aluminum patio furniture continues to grow in popularity. Aluminum does not carry the rust threat that iron does and the paint does not peel as regularly. The weight of cast iron is considerably more than cast aluminum patio furniture and it is available in many designs.

From trellises for gardens to table and chair sets cast aluminum patio furniture can be used to accent other patio furniture or offer a space for more intimate conversations. Items such as a small table and a couple of chairs can make space for after dinner seating for coffee or other beverage.

Due to the intricate design capabilities of cast aluminum patio furniture cross weave appearance is possible on tables, chairs, chaise lounges and just about anywhere you would appreciate the design. Being able to mass produce cast aluminum patio furniture has made it one of the leading metals used for outdoor applications. If the paint get damaged on a piece of cast aluminum patio furniture the bare metal will not be damaged to exposure to the elements. You can also set up pieces of similar design throughout your yard or patio to maintain consistency in your outdoor décor.

All of the features that make metal railings so desirable. Different kinds of metal railings. Different designs that can be done in metal railings.

There are many advantages to metal railings, and these will become apparant to you once you have read this article. Other materials are available for railings such as PVC, wood, or glass. But metal railings have the following advantages over these:

-Metal railings come in small, lightweight sections that can be crafted to suit any purpose.
-Metal railings do not rot or splinter the way wood railings do.
-Metal railings can be designed to suit a custom design without a lot of expense.
-Metal railings can be cast metal, or tubing material; depending on your budget, you have your choice.
-Metal railings are much longer lasting than wood or PVC, even in the most extreme outdoor settings.
-Metal railings, if they are properly coated wtih a powder coated paint, can last more than thirty years.
-Metal railings require little care other than a light cleaning from time to time.

The most commonly used metals in railings are Stainless steel, wrought iron, aluminum and brass. Let’s examine the advantages of each one of these metals:

Stainless steel is the most common material for railings. It possesses a great weight to strength ratio and holds color and luster better than other materials and is not subject to corrosion. It is very easy to work with since it can be pressed through a power press without suffering any damage. Stainless steel give a very modern look to the architecture of a building.

Wrought iron is another popular, commonly used material for railings. There is a certain “period” look that wrought iron gives to a building. Wrought iron is heavy, so it does not have the strength/weight advantage of stainless, but it is very strong and has little maintenance requirements. With the proper paint, it will require nothing further than light cleaning from time to time. If wrought iron does break, which is not easy to do, replacement is not easy, as re-welding would be required and you may not be able to get a similar pattern to replace it.

Aluminum is lightweight and durable, and able to be shaped into any straight pattern. It is difficult to make any curved patterns with aluminum, but if a straight or square style is desired, aluminum works perfectly. Aluminum is as easy to care for as stainless stell and is very durable.

Martin Forrester asked:


A ‘flue liner’ is the material used to line chimney stacks. Since 1965 houses with chimneys were usually built to include flue liners. They tended to consist of a clay liner which was designed to last the life time of the building. Prior to 1965 lining was not common place and chimneys were simply rendered with lime mortar.

There are three basic types of flue liners on the market today; cast in situ refractory lining, metal and sectional, solid liners.

Cast in situ refractory lining

A toughened rubber tube is inserted down the length of the flue and inflated. The structure of the flue is temporarily opened up at intervals of 2 meters and bends so that refractory blocks can be inserted to ensure the tube is in the correct position. A refractory concrete insulating mix containing pumice or vermiculite is then poured into the flue to surround the outside of the rubber tube. The tube is deflated once the mix has set, leaving behind a perfectly formed smooth cylindrical flue. Cast linings are the least expensive and amongst the simplest to install. However the success of the flue heavily depends on the skill of the specialist contractor. Water in the refractory mix can cause decay and migration and if the tube is not centralized properly, once installed it almost impossible to remove. The tubes are available in a range of sizes to accommodate different flues and fuel types.

The standard 9 x 9″ flue creates a 185mm diameter cast in situ lining and in accordance with The Building Regulations is suitable for both solid fuel open fires and gas effect decorative fires. The ratio of the flue size against the size of the fireplace is an important factor to consider. Get this wrong and it could result in a weaker draught. In most cases the ratio of the cross sectional area of fireplace opening to the flue should be a maximum of 8:1 (6:1 for single storey properties). The average register grate is 12″-18″ wide and 18-22″ in height above the grate so most fireplaces will accommodate a flue as small as 5mm diameter.

The flue size of fireplaces built before the 19th Century will require additional calculation. Most old chimneys need to be relined before they become re-useable as even those built with a lining may have a flue that is too big or inefficient for modern stoves and fires. Installing a new liner with a correctly sized flue will ensure you have a new sealed, efficient and safe chimney. Both Cast and Metal liners are suitable for solid fuel and wood appliances.

Metal Liners

There are three variations on metal liners available; flexible double skin liners, rigid metal liners and gas flex.

Flexible double skin liners are made from stainless steel whilst the inner skin is smooth the outer side is corrugated. They are installed by pulling the liner either up or down the flue on a rope where the ends can then be fixed into position. This type of lining is suitable for solid fuel, wood or gas effect fires and available in a range of diameters.

Usually used to reline large flues in wood burning stoves rigid metal liners are made of stainless steel with a minimum thickness of 1mm. and are installed and held in place with special clips at the joints. Space around the liners is back-filled with perlite or vermiculite.

Gas flex is used for closed gas fires and boilers. It is a light single skin liner providing a flexible and economic lining for gas burning appliances.

Sectional, Solid Liners

Sectional, solid liners are more likely to be used in the case where the existing stack is large or straight or if the stack is re-built, and will then incorporate the liner in the stack as it is re-built. Made of refractory concrete or pumice concrete the fuel liner is highly durable and like metal liners, solid, sectional liners are reversible and therefore have the advantage of not involving the introduction of water.

Wrought iron continues to be popular for many reasons.Learn a bit about the history and process of wrought iron railings and why people love them.

Wrought iron , including railings continues to be a popular choice for homes. Why has it retained its charm despite changes in the way people decorate their homes and gardens?

Wrought iron railings blends in with pretty well any décor and adds an elegant and rich feel to its environment. Whether you have railings around your porch, around your stairs or the perimeter of your home (fencing) or cottage, wrought iron looks great and is stable and durable.

Wrought iron railings have been around for several generations. Even as far back as the sixteenth century, it was used in expensive, wealthy homes and important buildings such as museums and government offices. The wealthy population wanted iron products and it took skilled craftsmen to create it for them in cast iron, wrought iron and in steel.

A bit about early iron railings

Despite ever changing trends, railings continue to blend with the times. Many things come and go in style and fashion but wrought iron seems to be immune to obsolescence. While most railings in the sixteen century, even for royalty, were made with wrought iron, some were even made of silver and gold with many styles and designs including monograms or family crests.

Early wrought iron railings took a very long time to make. They were fired until bright red and then the iron was hammered manually into the shape through labor intensive processes which made them extremely expensive and only owned by very wealthy and important people. Some had to wait a long time for their orders to be fulfilled through custom craftsmen.

Cast iron railings were done through hot liquid iron that was placed into molds made of sand. Cast iron railings weren’t easy to repair though and were prone to cracking. Mild steel railings were also quite popular in the middle 1700′s and they were easy to form so became very popular for railings and fences.

A little about modern Wrought Iron railings

As technology progressed, techniques were developed that would allow metal craftsmen more choices and the ability to manipulate iron rods into various intricate designs. Welding also developed and wrought iron became more widely available and more accessible financially. This also made repair more feasible.

While wrought iron is the same material as it always was, new techniques allow it to be less expensive to make and easier to treat, maintain and repair. You can buy it ready made or still, have customized orders done.

Regularly cleaning your iron and inspecting it for corrosion or rust can help it last longer and be around to be appreciated by your children and perhaps your grandchildren as well.

Markus Skupeika asked:


Have you got rust in your chrome bumper? Do you want to try any specific brand of cold drinks to clean rust from chrome?

There are so many rumors all over the world (wherever that specific brand of cold drink is available) about that specific brand, that it does not matter any more if it has a cleaning quality or not. It has got a name for itself.

Anyways, there are lots of ways that people employ to remove rust from chrome body – for example, car bumper, bicycle, etc. If some people are happy with the use of regular chrome polish, some people are happy with steel wool to remove rust from chrome. Most of them have their own reasons to show.

So, what is your take at this point? If you are not sure what people really try to clean chrome parts, let’s take a look at the following paragraphs. Apart from giving you some real life ideas, it may also help you to decide what you need to do.

Chrome polish and rag: This is one of the most popular ways to clean rust from chrome products. However, it is often used in less expensive products of daily wear and tear. For example this is used to clean rust from car bumpers or bicycles. And it is used when the amount of rust is not too high or when they have not damaged the metal a lot. However, you would need to polish the chrome well after cleaning it. Some people do not like the idea as it is sometimes too laborious and the output is not always very exciting.

Naval Jelly: Some people would use it to clean rust from chrome elements and some people are against it for their own reasons. However, it does not suit every metal and may cause harm.

WD 40: People sometimes use it to clean rust from iron products like cast iron. You would need to hose the cast iron product with WD 40 and leave things as it is for around 10 to 15 minutes. After that you would need to hose it again and scrub the metal with steel wool with more amount of WD 40 to clean it properly. However, after cleaning you would need to work hard to dry the metal element or it may get rust again.

Steal Wool: A lot of people will agree that steel wool is just the perfect thing to remove rust from any metal surface. They would manage and time and strength to rub the rust until it is clean. The best steel wool is that of #000000 grade (if you can find it in a local store). However, you would need to polish the metal well after rust removal.

Aluminum Foil: Some people use aluminum foil to clean rust from metal surface. However, you would need to polish the metal well after removing rust from the metal. For example, if you are using aluminum foil to remove rust from a chrome surface you would need to apply chrome polish after removing rust.

Organic rust removers: These are some of the best rust removal products that most of the people use to remove rust from metal. This is effective and mild and at the same time you do not need to work hard physically to clean rust – no scrubbing required. However, it is always recommended that you should select some organic rust remover so that it does not harm your skin or other elements.

So what are you using to clean rust from metal next time?

Kris Koonar asked:


Historically flat roofs have been used mainly in the Middle East, the American southwest including other places where the climate is arid and dry and drainage of rainwater off a house roof is not of great concern. As opposed to a sloping roof that is pitched at an angle a flat roof is flat with a more or less horizontal layout. In fact is not totally flat but usually incorporates a slight slope that is roughly equivalent to 1 percent of the run of the roof to aid draining water from the roof into gutters/drains located at the lower side of the grade.

Although sloping roof designs have been preferred in the US in the past flat roofs are fast gaining popularity because new technology has enabled a reduction/elimination of the disadvantages associated with flat roofs in cold climatic conditions that allowed formation of ice dams that blocked free flow of water off the roof making inhabitants suffer roof leaks as water pooled on the roof. An inherent advantage of a flat roof is that it is easier to inspect as compared to a sloping roof.

The flat surface reduces dead space, which is common to sloping roofs and creates usable space that can serve as a terrace garden or open outdoor space to be used as a relaxing area or for other activities. Low construction cost is another advantage attributable to flat roofs. They also lower costs for constructing upper floors in the house. Flat roofs allow the most efficient use of urban space, cater to energy savings and offer architectural freedom to conveniently cover complex architectural plans.

Flat roofs that invite regular pedestrian traffic are constructed more sturdily than those exposed to occasional foot traffic. The roof substrate of load bearing roofs is usually made from plywood panels that are 15mm in thickness where the joist spacing is not more than 480mm. 800 mm joist spacing would require 21 mm thick plywood. The face grain of the plywood is placed at right angles to the supporting joists with the long edges of the plywood panels laid in a brick bond pattern over the framing. Long panels are supported by nogging in the timber frame or incorporate tongue and groove edges allowing a continuous plywood surface over two spans.

The smooth flat surface created by structural plywood panels provides the most perfect base for the membrane overlays to be placed on top. The membranes are attached to the roof substrate using three different methods known as fully adhered, independent and semi independent.

Fully adhered membranes are attached completely to the surface, which should be very stable and have minimum flex. The membrane itself should be elastic and resilient to cope with any movement in the substrate. Bridging strips are used to cover the edging lines of the plywood panels in fully adhered systems. These strips are usually made from the membrane material itself. The fully adhered system has a higher resistance to foot traffic and is more stable in hot and cold contractions and expansions. It is also makes it easier to trace leaks.

Independent membranes are made to be non attachable to the substrate and are just laid on top. To prevent automatic adhesion under the heat of the sun there is a fiber veil on the membrane underside along with fiber backed base sheet membranes with open non-woven polyester on their lower side. These are usually used on concrete slabs or pre-cast concrete panels as they are ballasted with gravel and therefore heavy. It is difficult to trace leaks in this type of membrane attachment.

Semi-independent membranes are partially bonded to the substrate and are the best option in case of a less stable or partially damp bonding surface. The partial bonding is accomplished by adhesion through perforated vent sheet underlays or by applying adhesives partially in strips or certain areas only through trickle application of adhesives. Membranes that are fixed through flame bonding are partially flame bonded. This type does not require heavy protection and allows vapor to be diffused.

Metal railings will offer you several advantages over the other choices of materials, including PVC, glass, wood, and more. The advantages of metal railings include

• Detailed designs are easy to create with metal railings. Metal is very easy to work and it is lightweight, which makes it ideal for detailed and intricate designs.

• Rotting and splintering does not occur with metal railings, which is not the case with railings made of wood.

• Due to the light weight, these railings made of metal can be installed and used in many different areas and ways.

• Depending upon your budget and personal preference, you can decide whether you want your metal railings flat or casted.

• Metal railings are extremely durable and weather-resistant. This is unlike materials like PVC or wood.

• Metal railings can be covered with a powder-coated paint. This helps to make the railings even more durable and they may last as long as 30 years.

• Metal railings are low maintenance. All you will need to do is wipe them off periodically with a wet cloth.

Metals Used In Railings

There is a variety of metals that you can find in railings. Some of the more common metals that are used include:

1. The most common material that is used in metal railings is stainless steel. It is lightweight, but it is very strong. It is very durable and is not affected by the weather. It is also virtually maintenance free, which is a wonderful benefit. It is easy to work with and is a wonderful way to enhance your home.

2. Wrought iron railings are also very popular. This is mainly seen in period homes and is very traditional. It is very heavy, but it will last for a long time. You will enjoy the fact that there is very little maintenance. One of the downsides is that if there is a break in the railings, you will find that it will be very difficult to fix. Replacement railings will be difficult to match with your existing railings so you need to consider this before you make your decision.

3. If your ideal railing design is angles and straight lines, then aluminum is a wonderful railing material for you. Aluminum railings are extremely durable and very lightweight. They are not a good choice for curves and curlicues, so you want to keep that in mind. Maintenance is very simple and these railings will last you for many years.

4. If your budget will allow it, then you may want to use brass. It was a favorite material during medieval times for kings and other rich people, but it is not used very much in our modern time. You may see it as a covering over other materials for railings, but railings made entirely of brass are not seen very often. Brass is not a maintenance free material, however, because it needs frequent polishing to keep it looking beautiful.

Sarika Kabra asked:


While you may be excused for being confused while making your choice of furniture, your friends are not likely to be so kind in their comments when you finally pick up a piece just because you got sick of all the choices. Neither are your children going to spare your furniture just because you spent a packet buying it. It is best to make an informed choice to decide what works best for you.

From the traditional Amish made furniture to the modern factory made smooth finish set, from the classic carved Victorian piece to the atypical non-geometrical design, from a wide variety in the choice of material and colors, you name it and you have it. Think hard before you decide.

Here’s a guide to choosing the best material for your needs.

Wood:

Wood has further multiple choices like natural teak wood, pine wood, rosewood and artificial wood laminates. The difference in the original woods is mainly in the texture and grain and you would do well to have a look at what appeals to you. Teak and rosewoods are the more durable and expensive of the lot. Rosewood Amish furniture can last for years, and still look as good as new, so your money would be well spent.

Wood laminates offer a cheaper version with a modern look, but are handicapped with a short life span. If you intend moving soon to another city, however, it could well fit in with your plans as a cheap, smart alternative.

Metal:

If you want a more contemporary look, metal may work for you. The choice varies from wrought iron to sheet metal to cast iron pipes. A good wrought iron set has the advantage of being sturdy and long lasting. Be aware, however, that the items tend to look a bit dated with time, and it may then be time for you to move on to your next set of sheet metal.

Made of pressed sheet, this is again long lasting, though it may not be able to withstand boisterous children as well as wrought iron would.

Galvanized cast iron pipes are good for strong, light furniture, generally made in combination with a cloth or a nylon mesh.

Plastic:

If you opt for plastic, be ready for a large variety of cheap and durable, yet limited life furniture. Being a very versatile material, plastic can offer you variety like no other. Beware of cheap quality stuff, however, wherein you run the risk of items that may crack, get scratched, fade, or simply break after a while.

Glass:

Glass is yet another versatile material that will give your dining furniture that modern, special look. While an exclusive couple may like to go for the full molded glass pieces, but a combination of wood and glass may work wonders for those with small children. Try Amish dining furniture with a touch of modernity thrown in – ask your dealer to fit in a glass top on a wooden base to have the right mix of class and strength. Make sure, however, that the glass is 8mm to 12mm thick to be of adequate strength.

A word of caution in the end. Having made your decision, do not worry yourself sick thereafter. There will always be that better looking piece or a similar item available at a sale barely a few weeks after you purchased yours. Don’t get tense – be confident that you bought the best piece at the best price available at the time of your decision – or else you wouldn’t have bought it, would you?
