The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!

Many people will mix strip steel and steel plate together, which can usually be distinguished from the following points. First of all, the thickness of the steel plate is much thicker, and the thinner the strip steel is required, the better. Secondly, in appearance, the steel strip can be crimped and the steel plate is too thick to bend, even if it is bent, it is difficult to recover, because it is easy to break if it is bent too much. Thirdly, the strength of P295GH grade steel material, steel plate is higher than that of strip steel. The steel plate is suitable for construction engineering, while strip steel is only suitable for processing into hardware products.

Heat treatment specification and microstructure of p295gh grade steel material, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.Mechanical properties of 12Cr1MoV alloy plate:Tensile strength σb (MPa)：≥490(50); Yield strength σs (MPa)：≥245(25); Elongation δ5 (％)：≥22; area shrinkage ψ (%): ≥ 50; Impact energy Akv (J): ≥ 71; Impact toughness value αkv (J/cm2)：≥88(9).

p295gh grade steel material, Strip steel has obvious characteristics. First, it is thin and easy to bend, convenient for logistics and transportation, and saves logistics costs. Second, the surface quality of strip steel is good. Third, the strip steel is easy to process, and it can be processed only by straightening the bent part. Fourth, the strip steel has high precision and it is a good raw material for processing blades and saw blades. Strip steel is widely used in the manufacture of welded pipes, clamps, washers, spring blades, saw blades and other fields.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the p295gh grade steel material principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
