Jiaochi 840 type galvanized color steel plate Beijing wholesale market

Color Steel Plate Our company now has the most advanced color steel profiled plate equipment in China with complete specifications. Existing specifications: Jiao Chi, 3-bite 3, etc. Construction steel has high strength. It has good plasticity, toughness and high strength, and is suitable for building structures with large spans, high heights and heavy loads. Good plasticity. Under normal conditions, the structure will not suddenly break due to overload, but will only increase deformation, so it is easy to be discovered. In addition, the local peak stress can be redistributed to make the stress changes gentle. It has good toughness and is suitable for working under dynamic loads, so it is more advantageous to use steel structures in earthquake areas. Light weight. Steel has a large volume and high strength, but the structure is relatively light and can bear the same load with the same span. The weight of the steel roof truss is only /3~/ of the reinforced concrete roof truss at most, and the cold-formed thin-walled steel roof truss is even close to /. Light weight , can reduce the load on the foundation, reduce the cost of the foundation part, and at the same time facilitate transportation and hoisting. The material is uniform, and the mechanical calculation assumptions are more in line with the actual stress conditions of the steel structure. The engineering mechanics calculation structure is more in line with the empirical formula used in the calculation. Not much, so the uncertainty in calculation is small and the calculation results are relatively reliable. It is easy to make and the construction period is short. The local peak stress is redistributed and the stress changes tend to be gentle. It has good toughness and is suitable for working under dynamic loads, so it is more advantageous to use steel structures in earthquake areas.
