It has the following characteristics:Higher creep resistance,Excellent formability,Rupture and tensile strength at high temperatures,Corrosion and pitting resistance.

A572 Carbon Steel Bar

ASTM A572 steel bar is a popular grade of high-strength low-alloy (HSLA) steel that is typically used in structural applications. A572 steel contains chemical alloys that enhance the material’s hardness and ability to bear weight. There are five different grades of A572 steel plate: Grade 42, Grade 50, Grade 55, Grade 60 and Grade 65.

304L Stainless Steel Pipe

304L stainless Steels lower carbon content helps minimize/eliminate carbide precipitation during the welding process. This allows 304L stainless steel to be used in the “as-welded” state, even in severely corrosive environments.

A106 Carbon Steel Seamless Pipe

ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.

Galvanized coil: "efficient substrate" in batch anti-rust processing

Galvanized coil is a strip-shaped coil made from cold-rolled or hot-rolled steel sheets, coated with zinc through a hot-dip or electroplating process. It combines the triple advantages of steel sheet strength, zinc layer rust protection, and continuous coil processing. At a lower cost than stainless steel coil, it is a core rust-proofing substrate for mass production applications such as home appliances, construction, and automotive, addressing the challenges of carbon steel's rusting susceptibility and low single-sheet processing efficiency.

Galvanized pipe: a practical choice for rust-proof transportation

Galvanized pipe is a tubular material made from a carbon steel pipe (seamless or welded) with a zinc coating applied to the inner and outer surfaces via a hot-dip or electroplating process. With the combined advantages of "steel pipe's pressure resistance and zinc layer's rust resistance," it offers lower costs than stainless steel pipe, making it a mainstream pipe material in fields such as building water supply, gas distribution, and municipal engineering, addressing the rust problem of carbon steel pipe.

Galvanized sheet: the "economical choice" in the field of rust prevention

Galvanized steel sheet uses a cold-rolled or hot-rolled steel substrate with a zinc layer applied via hot-dip or electroplating. With the combined advantages of "steel strength + zinc rust resistance," it offers a lower cost than stainless steel. It has become a mainstream material for rust prevention in sectors such as construction, home appliances, and automobiles, addressing the rust problem of carbon steel.

Stainless steel bars: "multifunctional profiles" in precision manufacturing

Stainless steel bar is a solid bar made from stainless steel through hot rolling, cold drawing, or forging. Its cross-sections are typically round, square, or hexagonal. It combines corrosion resistance, high strength, and ease of processing, making it a core material for mechanical parts, precision components, and consumer goods, overcoming the rusting shortcomings of carbon steel bar.

Stainless steel coils: the "flexible substrate" for efficient processing

Stainless steel coil is made from stainless steel sheet, cold-rolled or hot-rolled, and then coiled into a strip. It combines the corrosion resistance and aesthetic qualities of stainless steel with the ease of continuous processing, making it a core base material for mass production in home appliances, decoration, food equipment, and other fields, addressing the low efficiency of processing single steel sheets.

Stainless steel pipe: the "core pipe material" in the field of corrosion-resistant transportation

Stainless steel pipe is an iron-based tubular material containing alloying elements such as chromium (≥10.5%) and nickel, produced through welding or seamless rolling. Its corrosion resistance, heat resistance, and hygienic properties have made it a core pipe material for media transportation in the food, medical, and chemical industries, addressing the rust problem of carbon steel pipe.
