Cold Storage Panel

Insulated Cold Storage Panels are what we usually call polyurethane cold storage board. We base polyurethane cold storage insulation panels on the requirements of users or specific projects. We use polyurethane foam as a sandwich board as an insulation material. This insulation material It is now the most common insulation material in large and medium-sized cold storage.

Cold Storage Door

Cold Storage Door refers to the door that is installed in cold storage equipment, freezer warehouse and other refrigerated environment equipment to keep heat preservation and airtight. The cold storage door adopts a high-strength aluminum alloy profile door frame, which has high strength, no deformation, beautiful appearance, and durable; We seamlessly welded the door leaf with 2.0mm stainless steel edging, sturdy and durable, no deformation, and reasonable structure.

Walk-in Refrigerator

Walk-In Freezer is a new type of cold storage mode. It replaces the original construction mode and operation mode of cold storage buildings with new architectural concepts such as standardization, modularization, and factorization. Different tonnages, modular combinations, and sufficient It meets the needs of deep processing of agricultural products, fine processing of food, and freezing and cold storage.

Wall Insulated Panel

Wall Insulated Panels, also called building exterior wall decoration integrated board. We made it of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials. Factory production and on-site bonding construction meet the current building energy-saving requirements, the preferred material to improve the external wall insulation level of industrial and civil buildings, and also the preferred material for energy-saving renovation of existing buildings.
