DX52D/SGCD1 Galvanized Coil Description

Compared to DX51D, the DX52D grade features improved mechanical properties, including lower yield strength and higher elongation, which provide superior formability. This makes it suitable for parts that require more complex bending, deep drawing, or stretching without cracking.

The product consists of a high-formability, low-carbon steel substrate protected by a durable zinc coating applied through the hot-dip process.

Scope of Application

Automotive Components: Non-structural body panels, brackets, seat frames, and reinforcement parts that require good formability.

Appliances: Complex-shaped panels for washing machines, dishwashers, and refrigerator liners.

Building Products: Formed roofing profiles, window frames, and door components.

Electrical Enclosures & Cabinets: Parts that require precise bending and assembly.

Scope of Application

Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.

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.

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.
