Heavy steel plate is hot-rolled thick steel plate produced under high-temperature rolling process, featuring high structural strength, outstanding impact resistance and stable mechanical performance. Mainly supplied in carbon steel, alloy steel and wear-resistant steel grades, heavy plates are indispensable raw material for heavy engineering and large-scale equipment manufacturing.
Common Grades & Standards
Regular grades: Q235B, Q355B, A36, S235JR, S355JR, NM400, NM450 wear resistant plate, 4140 alloy plate. Conform to ASTM, EN, DIN, GB standard; special alloy grades available per customer demand.
High tensile strength and good toughness, resistant to bending and heavy load pressure
Compact internal structure, uniform composition, stable performance across whole plate
Clean surface with fewer defects, strict thickness tolerance after flattening treatment
Flexible processing: cutting, drilling, bending and welding for diversified fabrication
Custom cut-to-size service according to customer’s drawing or required dimension
Thickness:10mm–200mm; Width:1500mm/1800mm/2000mm; Length:6000mm–12000mm or customized cutting size. Surface: as-rolled or shot blasted finish.
Widely used for bridge construction, shipbuilding hull plates, boiler & pressure vessel, mining machinery liner, heavy equipment base, engineering machinery, offshore platform and steel structure projects.
