Enclosure / Cladding System

Wall & Roof Panel Solution

Insulated sandwich panels (PU/PIR/EPS) and single-skin metal cladding. 50mm-200mm thickness, fire-rated options. Compatible with steel structure buildings for complete envelope solution.

Product Overview

A steel building is only as good as its envelope. Our cladding systems — including PIR/PU insulated sandwich panels and single-skin profiled sheets — provide thermal insulation, weatherproofing, and architectural finish in one integrated system.

Sandwich panels are manufactured on continuous lamination lines with zero-ODP blowing agents. The double metal skin with injected foam core delivers U-values as low as 0.18 W/m²K, meeting energy codes worldwide. Custom colors, profiles, and fire ratings available.

For cold storage and food processing projects, we supply PIR-cored panels with food-grade stainless steel interior skins and antibacterial coatings — compliant with HACCP and FDA requirements. Our cladding systems ship with all necessary trims, flashings, fasteners, and sealants — a complete envelope kit ready for installation. Typical lead time is 20–25 working days.
