Product Description

About products

The cold-drawn steel is used to forcibly stretch the reinforcement under normal temperature conditions with tensile stress exceeding the yield point strength of the original reinforcement, making the reinforcement produce plastic deformation to achieve the purpose of improving the yield point strength of the reinforcement and saving steel. Cold-drawn steel is the use of cold extrusion technology to draw various high-precision, smooth surface round steel, square steel, flat steel, hexagonal steel and other special-shaped steel through precise molds. The concept of cold drawing of reinforcement: for the purpose of saving steel and improving the yield strength of reinforcement, the method of drawing reinforcement with tensile stress exceeding the yield strength but less than the ultimate strength to produce plastic deformation is called cold drawing of reinforcement. Hexagonal steel is a kind of section steel, also known as hexagonal bar, which has a regular hexagonal section. Take the length of opposite side S as the nominal dimension Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular section and slightly blunt edges. Flat steel can be finished steel, also can be used as blank for welded pipe and thin slab for laminated sheet. Main uses: flat steel can be used as finished products to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in construction.
