Pir Sandwich Panel
Designed with a metal exterior and high-performance insulating core, this panel offers superior thermal insulation, soundproofing, and energy efficiency. It's ideal for buildings where energy conservation and comfort are top priorities, ensuring long-term durability and reduced environmental impact.
Product Introduction
It boasts Class A energy-saving and fire-resistant performance, with outstanding heat insulation and flame-retardant effects; the surface material of the panels can be made of color-coated steel plate, aluminum plate or stainless steel plate to suit different building scenarios and needs; relying on water-repellent materials and airtight structural design, it achieves excellent water tightness and air tightness, while also effectively reducing environmental noise interference; the core filling is high-strength PIR (polyisocyanurate) core material, which has stable performance and strong durability, and can fully support the long-term use needs of buildings.
Production Workshop
The company headquarters is located in a leading metal manufacturing plant, equipped with an integrated cluster of advanced production equipment: a combination of automated production lines, industrial robots, and precision machining tooling, covering the entire production process from raw coil materials to finished components. Large CNC machining centers, coupled with intelligent logistics systems, provide efficient and precise operation capabilities for the production process, supporting the large-volume, high-quality manufacturing needs of various metal parts (including tongue and groove plates).
Color Coated Steel Sheet Selection
Our color-coated steel sheets are constructed with a multi-layered composite structure, using cold-rolled steel sheets as a base, and then layering a coating, conversion layer, primer, and topcoat in sequence, ensuring top-quality products from the source. We offer a variety of coating options, including 2/1, 2/1M, and 2/2, to meet different application needs such as corrosion resistance, scratch resistance, and processing adaptability. The coatings have strong adhesion, a rich selection of colors, and long-lasting color retention, enhancing both the durability and safety of buildings while also revitalizing the aesthetics of building facades, making them an ideal choice for high-end metal cladding.
