(1) Structural steel: mainly used for the production of steel structural components, bridges, ships, and vehicles.
(2) Weatherproof steel: With the addition of special elements (P, Cu, C, etc.), it has good corrosion resistance and atmospheric corrosion resistance. It is used in the production of containers, special vehicles, and also for building structures.
(3) Automotive structural steel: High strength steel plate with good stamping and welding properties, used in the production of automotive FRAME, WHEEL, etc.
(4) Hot rolled special steel: Carbon steel, alloy steel, and tool steel for general mechanical structures, which are used in the production of various mechanical components after heat treatment engineering.
(5) Cold rolled raw plate; Used to produce various cold rolled products, including CR, GI, color coated plates, etc.
(6) Steel plate for steel pipe: With good processing performance and compressive strength, it is used to produce high-pressure gas pressure vessels filled with LPG, acetylene gas, and various gases with a volume of less than 500L.
(7) Steel plate for high-pressure vessels: With good processing performance and compressive strength, it is used to produce high-pressure gas pressure vessels filled with LPG, acetylene gas, and various gases with a volume of less than 500L.
(8) Stainless steel plate: Stainless steel has good corrosion resistance, mainly used in the food industry, surgical equipment, aerospace, petroleum, chemical and other industries.
