Carbon Steel Plate
Carbon steel plate is widely used hot-rolled flat steel with carbon as the primary alloy element. It balances cost and basic mechanical performance. Available in diverse thicknesses, it supports cutting, bending and welding. It serves general engineering, construction, machinery manufacturing and shipbuilding for conventional load-bearing structural components.
Available Grades
A36
Common structural carbon steel plate with good formability and weldability. It is widely adopted in building frames, brackets and general mechanical parts under normal ambient working conditions.
S235JR
European standard low carbon structural plate with guaranteed room temperature impact property. Ideal for steel structures, containers and equipment bases in non-cold critical environments.
SS400
Japanese standard universal carbon plate featuring stable comprehensive performance. Frequently used for machinery housings, support frames and simple metal fabrication projects.
A283 Grade C
Mild carbon steel suitable for low-to-medium load applications. It is a cost-effective choice for tanks, ductwork and non-critical structural assemblies.
SPHC
Hot rolled pickled carbon steel plate with excellent ductility. Mainly used for stamping, bending and deep drawing components in automotive and hardware industries.
Product Features
Excellent weldability and machinability, easy to cut, bend, stamp and process into varied components.
Cost competitive compared with alloy steel, controlling raw material expenditure for mass production.
Stable mechanical performance under normal temperature, reliable for conventional load-bearing structures.
Flexible size range covering thin to heavy plates, customizable specifications to reduce leftover waste.
Good surface condition, available with black hot rolled finish or pickled surface for further coating.
Applications
Building & Civil Construction
Used for steel frames, support beams, floor panels and structural brackets in factories, warehouses and commercial buildings.
General Machinery Manufacturing
Produce equipment bases, protective covers and ordinary structural parts for light industrial machinery and transport vehicles.
Ship & Container Fabrication
Suitable for container side panels, hull auxiliary structures and barges working under moderate marine conditions.
Storage Tank & Pipeline Projects
Fabricate low-pressure storage tanks, ventilation ducts and non-corrosive fluid transport pipeline components.
Metal Processing & Hardware
Raw material for stamping, bending and welding to make hardware accessories, metal brackets and engineering parts.
