PRODUCT DESCRIPTION SS400 hot-rolled steel coil is a marking method for Japanese steel products, and the standard number is JIS G3101, which is equivalent to Q235 material. It is a steel material. Q represents the yield of this material, and the following 235 refers to the yield value of this material, which is around 235. And the yield value will decrease as the thickness of the material increases. Due to the moderate carbon content, the comprehensive performance is good, and the strength, plasticity and welding properties are well matched, so it is the most widely used. Often rolled into wire rod or round steel, square steel, flat steel, angle steel, I-beam, channel steel, window frame steel and other section steel, medium and thick steel plate. Widely used in construction and engineering structures. It is used to make steel bars or build factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and is also widely us…
