High-performance insulated composite panels consisting of two color-coated steel skins with an insulating core (EPS, rock wool, PUR/PIR, or glass wool). Used for roof and wall cladding of industrial buildings, cold rooms, clean rooms, and commercial structures requiring thermal insulation and fire resistance.

Primary cladding for warehouses, factories, workshops, and logistics centers. EPS or rock wool core depending on fire requirements.
PUR/PIR core panels for cold rooms, blast freezers, and temperature-controlled warehouses. Excellent thermal efficiency with minimal thickness.
Rock wool or glass wool panels with anti-static, anti-bacterial coating for pharmaceutical, electronics, and food processing clean rooms.
Architectural wall panels for showrooms, supermarkets, sports facilities, and office buildings with custom colors and profiles.
A: For general warehouses in non-fire-critical areas, EPS panels offer the best value. For buildings requiring fire resistance (chemical plants, public buildings, high-occupancy), rock wool (A1 rating) is mandatory. For cold rooms and energy-critical buildings, PUR/PIR provides the best insulation. For acoustic needs, glass wool is preferred. Our engineers can recommend based on your local building code and project requirements.
A: As a general guide: tropical climates (25-35°C) — 50-75mm EPS or rock wool; temperate climates (10-25°C) — 75-100mm; cold climates (-10 to 10°C) — 100-150mm; cold rooms/freezers — 80-150mm PUR/PIR. The exact thickness should be calculated based on required U-value, local climate data, and HVAC system capacity.
A: Standard sandwich panels are non-load-bearing cladding. They support their own weight plus wind loads, but not structural dead or live loads. For load-bearing applications, we recommend combining panels with a structural steel frame (portal frame or multi-story steel structure), where the frame carries gravity loads and panels provide enclosure and insulation.
A: With proper installation and maintenance, color-coated steel sandwich panels last 15-25 years. PVDF coating provides the longest color retention (15-20 years), while PE coating lasts 8-12 years. The core material (EPS, rock wool, PUR) has a similar lifespan. Coastal or industrial environments may require thicker coatings (0.6mm+) and higher zinc/aluminum substrate for extended life.
A: Yes, we supply complete accessory packages including: self-drilling screws (with EPDM washers), foam closures, ridge caps, eave trims, corner trims, door/window flashings, sealant, and installation tools. We provide a detailed fastener schedule (quantity per m²) and installation drawings with every panel order.
