High compressive strength and high tensile strength. The compressive strength of the steel structure is relatively high, and it is suitable for the basic construction of bridges with a large load, and the weight is relatively light, which can reasonably reduce the load of the bridge itself, and has the advantages of low construction cost, convenient transportation and lifting, etc.
Wind resistance
Excellent wind resistance. Steel structures are light in weight, high in strength, and can prevent deformation, protecting most buildings.
Shock resistance
Strong shock resistance. Taking villas as an example, the roofs of low-rise villas are mostly sloped, so most of the surface structures are truss systems made of cold-formed steel structural parts. This system has superior shockproof performance and can resist about magnitude 8 earthquakes.
Durability
Currently, among the widely used construction materials, there is no more durable than steel. Steel is fire-resistant, light but strong, and creates safer structures than other building materials. Steel structures can withstand high winds, extreme weather, and seismic activity better than wood frames or concrete. With proper anti-corrosion treatment, steel structures will not rust or oxidize when exposed to moisture, and will not warp, rot or dent over time.
