High-Gloss Color Coated Profiled Steel Sheets & Complete Series Mechanically Made Sandwich Panels Supplier

The bright blue color steel corrugated sheet shown is the outer surface raw material of all mechanical sandwich panels. It adopts galvanized base plate with multi-layer color coating treatment, featuring anti-rust, waterproof, weather-resistant and fade-resistant performance, adapting outdoor long-term exposure environments. The trapezoidal wave structure greatly improves the bending resistance and drainage capacity of roof enclosure systems.

Our full sandwich panel product matrix differentiates two production crafts: machine-made panels feature tight integration, high flatness and large-scale rapid production; handmade composite panels realize thicker core layers and enhanced fireproof performance. Core materials include rock wool, magnesium oxysulfide and hollow glass magnesium, all reaching Class A fire resistance standard with excellent heat preservation, sound insulation and moisture-proof effects. Custom width, thickness, length, surface color and edge sealing structure can be produced according to construction drawing requirements. Each batch of panels undergoes fire resistance and compressive testing before delivery.

To meet the global demand for energy-saving building enclosure materials, our factory will expand automatic panel pressing production lines in Q4 2026, continuously upgrading all-series handmade and mechanically made sandwich panels.
