Specifications
Material combinations confirmed for the profile and environment
These are common supply ranges, not a fixed certification or design commitment. Final specifications, standards, coating and tolerances are confirmed in the quotation, sample and material certificate.
| Parameter | Common range / note |
|---|---|
| Thickness range | Commonly 0.25–0.80 mm; subject to coil and profile |
| Effective width | Approx. 750–1,000 mm; varies by rib geometry and overlap |
| Custom length | Cut to order within production, handling and transport limits |
| Substrate | Galvanized steel or aluminium-zinc alloy-coated steel |
| Surface finish | Color-coated systems; PE, SMP or PVDF selected for the environment |
| Color range | Standard colors and RAL references; special colors subject to coil MOQ |
| Reference standards | SNI 4096:2019 may apply to aluminium-zinc substrate; SNI 66:2024 may apply to prepainted zinc-coated sheet. Confirm applicability and certificates per order |
Applications
For common industrial-envelope requirements
02
Warehouse cladding
Suitable for exterior walls and selective refurbishment where speed and a clean finish matter.
03
Canopies and annexes
A practical covering for loading zones, walkways and light equipment shelters.
04
Temporary enclosure
Centralized production and simple handling support projects with compressed schedules.
Production
From coated coil to cut-length sheets
Each order begins with substrate, color and profile confirmation, followed by feeding, continuous forming, cutting and final inspection.
Coil verification
Thickness, color, coating and batch information are checked.
Continuous roll forming
Roll stations form consistent ribs and effective width.
Cut to length
Each sheet is produced against the project cutting list.
Packing and dispatch
Surface, edges and quantity are checked before protective packing.
Installation
Overlaps, fasteners and waterproofing details all matter
Installation must follow the project design and method statement so that fasteners, cut edges and seals do not compromise service life.
- 01
Verify purlin spacing, sheet direction and the starting line before installation.
- 02
Arrange side and end laps for prevailing wind and rain, using compatible sealing materials.
- 03
Drive fasteners vertically with controlled pressure to avoid crushed sheets or loose, leaking connections.
- 04
Remove metal swarf promptly and repair cut edges or scratches according to the coating system.
FAQ
Four common questions before ordering
01What is the minimum order quantity?+
MOQ depends on the profile, coil color and thickness. Standard materials can be scheduled by project; special colors are subject to coil procurement quantities.
02How long does overseas delivery take?+
Production and shipping depend on order volume, destination port and vessel schedule. We provide an estimated timeline after specifications and payment terms are confirmed.
03Can the product be customized?+
Yes. Profile, thickness, cut length, coating and color can be tailored. Extra-long sheets remain subject to container and inland transport limits.
04What is the warranty period?+
Coverage and duration are confirmed according to substrate, coating system, environment and contract. Installation damage and corrosive exposure require separate assessment.
