Flat Steel Bar

Description

Flat Steel Bar is widely used in various fields because of its excellent properties, such as high strength, corrosion resistance and long service life.We can produce and supply various specifications of steel bars, flat bars, square bars, round bars, etc. Welcome to consult.

Product Description

Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and slightly blunt edges.
Flat steel is divided into carbon steel flat steel, galvanized flat steel and stainless steel flat steel according to material.
According to the forging process, flat steel can be divided into: hot-rolled flat steel and forged flat steel
1. Hot rolled flat steel
Hot-rolled flat steel is a general-purpose rolled long steel strip with a rectangular cross-section. Its specifications are expressed in millimeters of thickness * width. Flat steel can be made into finished steel products for structural members, ladders, bridges and fences, etc. Flat steel can also be used as billets for welding and welding and as slabs for stacking thin plates. (Material: Q215, Q235), executive standard: GB704-1988 replaces GB704-83. This standard is applicable to general hot-rolled flat steel cross-sections with a thickness of 3~60mm, a width of 10~200mm, and a rectangular shape. Delivery status: Flat steel is delivered in straight strips. Measurement method: fixed-length flat steel and door length are delivered according to the theoretical weight.
2.Forged flat steel
Forged flat steel is a long forged steel plate with a rectangular cross-section. Unfair forging can obtain forgings of a certain shape and size. At the same time, it can significantly improve the as-cast structure of the steel and increase the density of the steel; it can change the distribution of the fiber structure, eliminate anisotropy, improve the mechanical properties of the metal, and make the strength and Toughness is improved; large quantities of steel and low plasticity high alloy steel can be processed. Forged flat steel is mainly high-quality alloy steel, mainly used as springs, tools and important mechanical parts.
Main uses: Flat steel can be used as finished material for making hoops, tools and machine parts, and can also be used as house frames and structural members of escalators in buildings.
