Product Description
Flat steel refers to steel with a width of 12-300mm, a thickness of 4-60mm, a rectangular cross-section and slightly blunt edges. Flat steel can be finished steel, and can also be used as blanks for welded pipes and thin slabs for stacked thin plates. As a finished product, flat steel can be used to make hoop iron, tools and mechanical parts, and it can be used as structural parts of house frames and escalators in construction.

The Division provides you with professional technical services. After years of hard work and development, the factory has a certain scale and strength. Provide higher and better services for steel users who need different profiles. 
Hot-rolled flat steel can be finished steel, mainly used for components, escalators, bridges, fences and other equipment.
Flat steel can also be used as a blank for welding and welding and a slab for stacked thin plates. The reason why cold-drawn flat steel is semi-finished steel is that it can be divided into cold-drawn polished stainless steel flat steel and hot-rolled acid white, sandblasted stainless steel flat steel. Flat steel can be composed of various stress components according to the different needs of the structure, and can also be used as a connector between components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc.
