When using metal camlocks and GI (Galvanized Iron) sheets with PUF panels, you're typically working with a robust setup for insulated enclosures like cold rooms or industrial partitions 1. Metal Camlock for PUF Panels: Camlock System: A mechanical locking system used to connect PUF panels tightly. Usually made from galvanized steel or stainless steel for durability. Ensures airtight and thermally efficient joints between panels. Camlocks are embedded inside the panel during manufacturing. Advantages: Quick assembly/disassembly Strong interlocking — improves structural integrity Reduces thermal bridging and air leakage 2. GI (Galvanized Iron) Material for PUF Panels: GI Sheet Properties: Steel sheets coated with zinc to prevent rusting. Common thickness: 0.8 mm (varies based on application). Surface finish: Plain, pre-painted (PPGI), or plastisol coated. Where GI Is Used: Acts as the outer skin on both sides of the PUF panel. Used for both interior and exterior-facing panels. Suitable for industrial use, warehouses, and general-purpose insulation. PUF Panel Construction (with GI & Camlock) Common Applications: Cold storage rooms Cleanrooms Prefabricated buildings Telecom shelters Industrial warehouses
