High-strength, normalized low-alloy structural steel plates supplied to ASTM A633 specification. Available in Grades C, D and E, these plates are engineered for welded, riveted or bolted structural constructions where improved toughness and strength are required compared with standard carbon steels.

Key features

  • Conforms to ASTM A633 specification for normalized high‑strength low‑alloy structural steel plates
  • Offered in Grades C, D and E to meet different strength and toughness requirements
  • Supplied as plate material suitable for welding, cutting, forming and machining
  • Mill test documentation available: EN 10204 3.1 and 3.2 certificates on request

Typical applications

  • Heavy structural components (bridges, buildings, platforms)
  • Cranes, hoists and lifting equipment
  • Construction machinery and off‑road equipment
  • Fabricated structural sections, gussets and reinforcements

Supply options and services

  • Stock availability for prompt delivery from industrial inventories
  • Cut-to-size and shearing services available to customer dimensions
  • Surface condition and additional processing (coating, shot blasting) can be provided per order
  • Full traceability with mill test certificates (chemical and mechanical test results)

Why specify ASTM A633 plates

ASTM A633 plates provide a balance of higher strength and improved toughness relative to ordinary carbon steel plates while maintaining good weldability and formability. Selecting the appropriate grade (C, D or E) lets specifiers optimize structural performance versus material cost.

For quotations, available sizes, lead times and certification copies, provide your required grade, plate dimensions (thickness, width, length) and quantity.
