Overview

DX51D Galvanized Steel Coil is a primary EN hot-dip galvanized forming grade for roll-forming, roofing and cladding profiles, ducts, and general commercial fabrication on export programs. Procurement should lock DX51D (or DX51D+Z), zinc coating mass class, thickness × width, surface finish and oiling, edge condition, max coil weight or ID/OD for container loading, and EN 10204 3.1 documents with coil identity. Coating class and base metal thickness drive outdoor durability and formability—state both on the RFQ. Align packing orientation, destination port, and any third-party inspection before mill release.

Applications

Duct and HVAC systems
Commercial cladding and gutters
General galvanized forming export

FAQ

What do I need for a firm DX51D GI coil quotation?

Send grade (DX51D+Z or agreed equivalent), zinc coating mass, thickness, width, surface, quantity or container target, coil weight/ID preference, destination port, packing, and whether EN 10204 3.1 MTC or third-party inspection is required.

How is DX51D different from structural galvanized grades?

DX51D is a commercial forming grade for roofing and light fabrication. Structural coated grades (for example S280GD / S350GD class) need higher strength confirmation—state the mechanical requirement on the RFQ.

Can you supply sheet instead of coil?

Yes. Confirm cut length and flatness for sheet, or open the DC01 galvanized sheet page when fixed blanks are preferred over continuous coil feed.

What packing is used for export GI coil?

Seaworthy coil packing with waterproof wrap, edge protection, and steel strapping is selected by order. Eye-to-sky or eye-to-wall orientation can be discussed with the shipping plan.
