Standards, inspection and approvals

• Produced to DIN 17100 for general structural purposes
• Common third-party approvals available (supplier lists ABS, DNV, GL, CCS, LR, RINA, KR, TUV, CE)
• Third-party inspection and mill test certificates can typically be provided on request

Typical applications

• Structural components for buildings and bridges
• Crane booms, chassis and mobile equipment
• Machinery parts and welded structures
• General heavy fabrication where high strength and weldability are required

Ordering notes

• Thickness, length and surface finish options depend on mill capability and order quantity
• Confirm required impact test temperature and certificate level (e.g., EN 10204) when requesting quotations
• For commercial enquiries, request for quotation (RFQ) with required dimensions, quantity and delivery terms
