Stainless steel channel is a corrosion-resistant structural profile with a C-shaped cross-section. It combines the high strength and easy framing capabilities of the channel design with the durability, hygiene, and aesthetic appeal of stainless steel, making it the ideal choice for applications where longevity, cleanability, and resistance to harsh environments are paramount. Classification: Channel Steel

DC01 Galvanized Sheet

DC01 galvanized sheet, also available as cut sheet and plate, is cold rolled low carbon steel substrate conforming to EN10130, with hot-dip galvanized coating on surface. It combines the good stamping performance of DC01 base steel and excellent anti-corrosion property of zinc layer. It has good ductility, flat surface, reliable weldability and easy machining, suitable for bending, punching and shallow drawing. It is widely used for sheet metal housings, hardware fittings, electrical cabinets, construction accessories and general anti-rust structural parts.

SS400 Carbon Steel Coil

SS400 according to material grade and name defined in the JIS G 3101 standard, The first S stands for "Steel", the second S stands for "Structure", and 400 for the lower limit tensile strength of 400 MPa. Ordinary structural steel with a tensile strength of 400 Mpa.This steel is the most widely used in JIS standard. Its use covers structures such as bridges, ships, vehicles, etc., in the shape of steel plates, steel bars and sections, almost all auxiliary materials for machinery and structures are used.

X42 Carbon Steel Pipe

API 5L X42 line pipe and API 5L X52 line pipe (Seamless and welded pipe) of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc. Actually, X42 and X52 etc. denote the minimum yield strength of the pipe steel. X42 has the minimum yield strength of 42 kilopound/square inch and X52 has the 52 ksi.

PPGI DC01

Prepainted galvanized steel coil is a kind of colour coated steel coil (PPGI coil). It uses galvanized steel as the base metal. The zinc layer offers strong corrosion resistance. Plus with painting, it is more durable than galvanized steel.The metallic coated steel then experiences some cleaning procedures, pre-treatment solutions and ultimately gets multiple layers of organic coatings, including laminates, vinyl dispersions, and paint. This continuous technique of applying different coatings is referred to as coil coating. Therefore, the steel coil doesnt require painting or finishing when employed in finished products.

AH36 Carbon Steel Plate

AH36 is a high-strength shipbuilding steel plate, one of the most common grades used in marine and offshore structural applications. It is strong, tough, and offers good weldability and formability to meet the demands of ship construction. As a grade that requires classification society certification (e.g., ABS, LR, DNV), it is important to know its key attributes, which include a minimum yield strength of 355 MPa (51 ksi) and guaranteed impact toughness at low temperatures.

ST42 Carbon steel pipe

The tensile strength of ST42 Carbon Steel Pipe shall not be less than 42kgf/mm2, which is 420MPa.ST42 Carbon Steel Pipe is a German standard seamless steel pipe, which is widely used. German standard seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for fluid transportation .

1020 Carbon Steel Coil

1020 carbon steel is a commonly used plain carbon steel. It has a good combination of strength and ductility and can be hardened or carburized.1020 carbon steel which contains 0.12 to 2% carbon. This steel category gains hardness and strength with heat treatment when the percentage of carbon content increases but the ductility is reduced.
