Notes:
Each grade (DX51D, DX52D, DX53D) can be supplied in thin, medium, and thick gauge coil specifications.
Thickness & strength based recommended application scenarios are relatively suitable for actual market.
The width, coil length and coil weight can also be customized according to the requirement of factory and transportation.
Our color coated steel coil (PPGI) available at [royalsteelgroup.com/ppgippgl] support extensive customisation to fit diverse‑project demands.
We supply base substrates including DX51D, DX52D, DX53D and other standard grades. Zinc coating weights can be adjusted to Z275 or higher for superior anti‑corrosion performance. These coils feature flat consistent surfaces and solid forming capability for further processing.
Available key specifications:
- Thickness: 0.12‑1.2 mm
- Width: 600‑1500 mm, adjustable upon client requests
- Coil weight & coil length: flexible custom options to match your production schedule and shipping constraints
Boasting reliable mechanical properties and neat visual finish, our PPGI steel coils products are widely used for roof panels, wall cladding, household appliance components, industrial equipment and general building material applications.
We tailor steel coil solutions around your actual project needs, delivering better efficiency, long‑term durability and stable visual effect to maximize your material value.
