Construction section steel is formed by rolling and cold bending of galvanized steel sheet, and its section is V-shaped, U-shaped, F-shapes, T-shaped, trapezoidal or similar to these shapes.
Mainly used as floor deck, but can also be selected for other purposes. The advantage is that the construction is convenient, fast, saves steel bars, can be used as a steel formwork, and has the advantages of low cost and high strength.
An iron-carbon alloy with a carbon content of 0.04%-2.3% in architectural steel. We usually refer to it together with iron as construction steel. In order to ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%.
In addition to iron and carbon, the main elements of construction steel are silicon, manganese, sulfur, phosphorus, etc. The other ingredients are there to differentiate the properties of the steel.
1. Application in decoration engineering. In addition to the walls and columns, automatic telescopic doors, rolling shutters, handrails of ladder fences, handrails of balconies, rainwater downpipes, flagpoles, streetlights, and arcade frames, in the kitchen and bathroom countertops, sinks, and supports of residential houses.
2. Application of roof. The early buildings with stainless steel roof include Savoy Hotel in London, Eurostar railway station, Chrysler Building and Empire State Building in New York, as well as the Kuala Lumpur twin tower perjonas building, Shanghai Jinmao Building and Hong Kong Convention and Exhibition Center built in Asia in the 1990s.
3. Application in reinforced concrete. Stainless steel bars are used in reinforced concrete structures to improve strength and resist the harsh marine environment, as well as the corrosion and corrosion resistance of chloride formed in the concrete to the embedded reinforcement.
