More and more people who need a home or a building for their business turn their attention to the affordable and lightweight construction systems with metal structures. If 10-15 years ago wood was the main alternative of the masonry, today there is a growing popularity of metal buildings – in both residential and commercial environments, due to the many advantages they provide.
Metal structures made of galvanized steel are the ideal solution for solving many of the limitations of traditional building materials and systems. The strength of steel profiles, combined with the service life of connections and joints created with special screws, make the buildings on metallic structures an ideal choice even for areas with a harsh climate or seismic activity.
Metal constructions are made of semi-finished steel products produced by the steel industry; depending on the specific operating conditions, there are several categories of steel, including:
- steels for general use, delivered in the form of hot-laminated products, classified according to their breaking strength
- atmospheric corrosion resistant steel, obtained by alloying it with copper, phosphorus, chromium or nickel
- fine grain steels for welded constructions
- brittle-fracture resistant steels at low and very low temperatures, obtained by alloying steel with nickel
- alloyed steels (with chromium) for special items, such as high-strength screws
Physical and mechanical performance of steel is determined by laboratory tests, of which the most important is traction.
Other laboratory tests on the metals used in construction include:
- testing the hardness of the material, which consists in measuring resistance of a metal surface to a hard steel bar, driven by a constant force
- testing the resilience, also known as the bending flexural test
- the bending test carried out under regular working conditions, in order to assess the plastic deformation capacity of steel
- the fatigue test, which aims to appreciate the behavior of steel at variable, periodic demands.
Laminated and other semi-finished metal products
Laminated products are standard semi-finished steel products made by the steel industry in the form of:
- metal sheets made by hot lamination of carbon steel or alloyed in the form of sheets of different thicknesses
- laminated profiles with different shape and dimensions of the cross-section
- construction and installation pipes made of steel, hot-laminated or welded
- cast iron pipes, fittings and flanges, lead pipes, pressure or drain pipes, as well as installation pipes made of copper, zinc or galvanized steel
- rivets, screws, nuts etc.
- fittings for carpentry
Non-ferrous metal products
Metal building supply products may also include non-ferrous metal products:
- aluminum and aluminum alloys in the form of wires, sheets and profiles
- zinc and copper in the form of wires, sheets, pipes used in installations, roofing materials etc.
- lead, used mainly for installations
Non-ferrous materials are used on a smaller scale as alloys:
- brass (copper and zinc) and bronze (copper and tin) used for installation and fittings
- duralumin (aluminum and magnesium)
Metal building kits typically include panels, trim, fasteners and various accessories and can be standard or customized for various building types and sizes. Find some of the best metal building kits at CanAm Steel Buildings for satisfying results.
