polyurethane sandwich panel manufacturer

The cold storage sandwich panels are generally refers to the PU/PIR sandwich panels,which has best thermal insulation performance,are widely used in various low-temperature roofs and walls.   Common applications as below:   1. Various cold storage systems: ambient temperature cold storage, low temperature freezing storage, constant temperature and humidity warehouses, pre-prepared food warehouses and kitchens, etc.   2. Food factories and workshops: fruit and vegetable preservation and processing workshops, poultry slaughterhouses, aquatic product processing workshops;   3. Various cold chain logistics warehouses: logistics park cold storage, ambient temperature cold chain warehouses, low temperature cold chain warehouses, cold chain distribution centers, etc.   4. Agricultural products and aquaculture: crop seed storage warehouses, low temperature mushroom storage warehouses, agricultural product storage warehouses; low temperature aquatic and seafood storage warehouses, etc.;   5. Pharmaceuticals and chemicals: vaccine cold storage, pharmaceutical storage cold storage, low temperature sterile laboratories, biobanks, low temperature chemical storage, explosion-proof cold storage, etc.;   6. Commercial and mobile cold storage: container mobile cold storage, refrigerated trucks, supermarket cold storage rooms, frozen warehouses, etc.

Sandwich panels, used for walls and roofs, are widely used in various steel structure factories, large warehouses, clean rooms, logistics warehousing, and cold storage facilities due to their excellent thermal insulation performance, high strength, good waterproof performance, light weight, easy installation, and short construction period. The significant advantages of sandwich panels are as follows:   1. Excellent thermal insulation performance: Sandwich panels typically use EPS, rock wool, and polyurethane as insulation core materials, providing excellent insulation performance without the need for additional insulation layers;   2. High structural strength, wind resistance, and strong corrosion resistance: Sandwich panels use color-coated galvanized steel sheets as the base material, resulting in high structural strength and good wind resistance. The surface can be coated with highly weather-resistant and fluorocarbon coatings, offering good corrosion resistance and aging resistance;   3. Excellent sound insulation and fire resistance: Different sandwich panel core materials can be selected to meet different application requirements. For example, large logistics warehouses can choose Class A fire-resistant rock wool core materials; large computer rooms can choose glass wool core materials with good sound insulation; and cold storage can choose polyurethane core materials with better thermal insulation performance.   4. Good sealing and waterproofing: Sandwich panels are generally sealed with tongue and groove joints and sealant, resulting in good waterproofing performance.   5. Lightweight, quick construction, and short construction period: Compared with traditional wall panels, sandwich panels are lighter and suitable for light steel structures and roof and wall renovations. They can be directly assembled on-site, simplifying construction, shortening the construction period, and greatly reducing labor costs.   6. Beautiful appearance and high cost performance: The surface of sandwich panels is made of color steel plate, which can be designed and selected in different colors, making them beautiful and elegant. Furthermore, color steel plates have a long service life, are easy to maintain, and offer high overall cost performance.
