Import 930 Secret Nail Insulated Roof Panel — Buy in Bulk from Supplier in China

The 930 Secret Nail Insulated Roof Panel is a PU sandwich panel designed for thermal insulation and structural strength in roofing applications. It features a secret nail connection system that improves waterproofing by eliminating exposed fasteners while simplifying installation. The panel’s core material is polyurethane, which provides a high R-value for energy efficiency in commercial, industrial, and residential buildings.

This panel is engineered with a lightweight design to reduce structural load, making it suitable for large-span buildings such as warehouses, factories, and agricultural facilities. The outer steel sheets are typically 0.4-0.8 mm thick, with a standard color-coated or galvanized finish for corrosion resistance. The polyurethane core density usually ranges from 38 to 42 kg/m³, offering a balance between insulation performance and weight. Industry-standard fire ratings for such panels often meet or exceed GB 8624 Class B1 (flame-retardant).

Buyers in cold storage, logistics centers, and industrial construction use these panels for their durability and thermal efficiency. The secret nail system allows for faster assembly, reducing labor costs, while the panel’s interlocking edges ensure a tight fit. Confirm packaging, loading capacity per container, and incoterms with the supplier, as these depend on project scale. The panels are typically supplied in lengths up to 12 meters, with custom cutting available on request.
