cold room panel supplier

Coastal or rainy regions often experience high salt spray, high humidity, strong ultraviolet radiation, and frequent rainfall, which directly accelerate the corrosion, aging, core material moisture absorption, and sealant aging of sandwich panels.   The durability of sandwich panels with different core materials and coatings varies in coastal/rainy regions, as compared below: 1. Fluorocarbon coated high-zinc PIR sandwich panel: Service life 15-25 years, up to 25 years with regular maintenance; ideal for cold storage, industrial plants, and clean rooms in coastal high-salt-spray and tropical rainy areas; 2. Polyester coated ordinary galvanized PU sandwich panel: Service life 8-10 years, 10-15 years in inland rainy areas; suitable for ordinary factories and warehouses in inland rainy areas; 3. Polyester coated rock wool sandwich panel: Service life 5-8 years; insulation performance significantly decreases after 3-5 years in high humidity environments. This product is only suitable for ordinary factory buildings in dry areas and is not recommended for use in coastal or rainy areas.   In summary, for coastal and rainy regions, it is recommended to choose PIR sandwich panels with a high zinc layer and fluorocarbon coating. Their durability fully meets the needs of the building's entire life cycle, making them the optimal choice for steel structure building envelope systems, especially suitable for building scenarios in tropical coastal and rainy countries in Southeast Asia such as Indonesia.  

Cold storage panels are prefabricated materials made for keeping spaces cold. They have two strong outer layers with thick foam inside. The outside is usually steel or aluminum. The inside is foam that blocks heat. The panels fit tightly together with special edges and locks to stop air leaks. You should care because these panels save money. Without them, keeping things cold costs a lot. --First, they save energy. Cold rooms run compressors all day. If walls leak, compressors work harder and bills rise. Good panels have very low heat transfer. A 100mm panel works better than a thick regular wall. --Second, they protect your products. Food, medicine, and flowers need steady cold. These panels keep temperature steady and stop drafts and moisture. --Third, they last long. Steel outer layers resist damage and rust. Foam inside does not soak water or grow mold. Panels are modular, so you can move or add to your cold room later. --Fourth, they stay clean. Smooth surfaces have no cracks for germs. You can clean them with strong chemicals without damage. Some have extra germ protection. --Fifth, they install fast. Traditional building takes weeks. Panels go up in days. That means less downtime and faster profits.   Propanel (propaneltech.com) makes PU and PIR panels that work well in real use. They help you choose the right panel for your needs. Cold storage is not guesswork. Build it right the first time.
