Choosing between timber or Steel frames sometimes comes down to considering the pests where you will be building. Termite damage in Australian homes costs home owners millions of dollars every year in repairs. A steel framed and trussed kit home provides extra protection against termites. There's not a termite in the world that can eat its way through Steel! If you live in an area with termites, steel is the best choice for your home construction.
With the propagation of mold and mildew in residential buildings, using steel minimizes these infestations. Mold needs moist, porous material to grow. Steel studs do not have those properties. This will prevent many people with mold allergies from needless suffering and in severe cases, death.
Mig welders also use a shielding gas to prevent contamination at the weld area. With arc welders this is similar in a sense to the flux coating on a welding electrode. The need for shielding gas does limit a mig welder as to the portability of the machine and is not very useful if welding in a stiff wind as the gas gets blown away. There is now however a flux The link between Steel and the US cored welding wire for mig use that removes the need for shielding gas.
There are other elements added to iron to produce steel. They include manganese, vanadium, tungsten and chromium. It is the latter that that holds the key to making stainless steel springs, for when a minimum of 12% of chromium is added to the steel making process, you produce a metal that is highly resistant to oxidation and the characteristic reddish brown rust stains. Nickel is also added to the mix at about 8%.
Steel, like various other metals, is an alloy. In the case of steel, iron ore is the primary material used. Manufacturers then add carbon, along with various other elements, including things like tungsten, chromium, and etc. The ratio in which these elements are added depends primarily on what purpose the steel is being manufactured for.
Steel is able to be recycled. If your church ever feels the need to get rid of the building it can be recycled. If the building stands for many years and never needs to be moved, you can take pride in the fact that you own an eco-friendly church building. You will own a green building that makes the world and the planet a nicer and much better place to live.
While learning how to weld steel is quite an easy process, the basics of welding need to be learned from both a practical and a theoretical point to get things right from the beginning. Many hours can be wasted through trial and error welding where some simple tuition can get you welding very well in a short period of time.
