Sherardizing - is the process of placing steel into an enclosure in which it is surrounded with metallic zinc dust and then heated.
Castellated Beam - steel beam which can be altered for a longer span without increasing its weight. The web is flame cut in a zigzag pattern and then the two elements are welded back together in a way that creates a deeper section, thus increasing spanning potential.
Galvanization - corrosion resulting from the contact of dissimilar metals in the presence of an electrolyte, such as moisture. To prevent this, different metals should be separated from each other by a non conductive barrier such as rubber or neoprene.
Square - a measurment roofing materials are estimated, sold and installed by. One square is equal to 100 square feet.
Extrusion - is a process through which solid metals are shaped to a required form. A piston
pushes a heated billet of metal through a shaped die. The extrusion process can produce very intricate sections for a variety of applications.
Breakforming - is a process through which solid metals are shaped to a required form. It is a bending operation applied to plates or metal sheets in which successive, one dimensional bends produce the desired shape.
Light Gauge Framing - an aluminium framing system that is lightweight, fast to erect, decay-proof and dimensionally stable. The system is installed like a wood stud system and can span up to 32 feet high with light loads.
Reinforcing Steel - are steel used in concrete construction to compensate for the lack of tensile strength in concrete. Typically available in the form of either deformed bars or welded-wire fabric.
Built- up sections - are constructed from a combination of standard structural steel sections. They are used to solve specific structural problems.
-processes of welding
Soldering - the joining of metal elements by mean of another metal that has a melting point much lower than that of the base metal.
Brazing - the joining of two or more pieces of metal at a temperature of 800F or above, using a non-ferrous filler metal with a melting point below that of the base metal. The filler metal is distributed between the surfaces of the joint by capillary action. Used for brass, bronze and some aluminium.
-method of heat treating steel
Annealing - heating the steel to a high temperature, 1350F to 1600F controlled cooling to soften the steel and change its ductility.
Quenching - rapid cooling from a high temperature by immersion in water or other liquid to increase hardness.
Tempering - Re-heating to less than 1350F after quenching and slowly cooling to restore ductility.
Casehardening - controlled cooling produces a hard, high carbon surface over a relatively softer steel core.
