Based on the principle of quality and respect for customers, BBNsteel maintains good cooperative relations with customers in home and abroad. With modern management, high-quality products, reasonable prices and comprehensive after-sales service, we provide our customers with high quality and low price A573 grade 70 steel sheet products.
The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of A573 grade 70 steel sheet cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.
The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of A573 grade 70 steel sheet structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.
The properties of A573 grade 70 steel sheet ASTM A36 steel allow it to deform steadily when the stress increase exceeds the yield strength. This ductility enables the building to stand still after meeting the structural limit in an emergency. Other A573 grade 70 steel sheet high-performance steel, such as bridge strand, has very strong strength and brittleness, and its deformation is minimum before severe fracture of bridge strand.
