The A709 grade HPS70W bridge steel plate, thin steel plates are more convenient for cutting. Since the thickness of the thin steel plate is basically below 4mm, it is very easy to construct during cutting, which also reduces the work intensity of the construction personnel and speeds up the work efficiency of cutting. There are different materials for thin steel plates, such as ordinary carbon steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, silicon steel for electrical engineering, etc..
Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, general metal structural parts for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads. A709 grade HPS70W bridge steel plate It is used in hot rolled or normalized state. In addition, Q345 steel is also widely used in construction, bridges, vehicles, ships, pressure vessels, etc.
Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.
Sulfur is a very harmful element in A709 grade HPS70W bridge steel plate steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of A709 grade HPS70W bridge steel plate steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
