cold room sandwich panel factory

For a good cold room, to use the right way to finish the installation is very important, cause the cold storage room requires excellent sealing performance--Once the sealing performance cannot be guaranteed, It may greatly increase energy loss and spoilage of goods.    The cold storage sandwich panels—it is usually composed with 2-layer pre-painted steel sheet with polyurethane(pu)/polyisocyanurate(pir) insulated core material. As is known to all, the pu/pir is the best thermal insulation building material—so it gives the best cold storage performance with B1 fireproof at the same time.    First of all, ensuring that the quality of the cold storage composite panels is good is the top priority. Propanel, just focus on supplying the pu/pir cold room sandwich panels, give customers the best solution also best price at the same time.   Secondly, ground site preparation and inspection must be done before installation. If the foundation is uneven - the panels won't line up properly - this can cause gaps to appear, ultimately allowing cold air to escape.   Thirdly, node connections are easily handled improperly. Nodes such as column edge connections, wall corner connections, and suspended ceiling points require professional personnel to connect them according to professional instructions. Improper operation can cause cold bridge phenomenon, finally leading to energy loss and damage to the cold storage panels.

Sandwich panels can be customized for design and size to meet exact project specs for sure.    Common sandwich panel’s thickness varies from 30mm to 300mm, and lengths from 400mm to 12000mm. Factories use automated cutting for precision during production. Quality checks test thickness fittings and core density to ensure standards. While the core materials of sandwich panel also allow custom options: EPS for light weight, rock wool/glass wool for sound control and fire safety, and PU/PIR for better insulation. As professional rock wool panel china manufacturer as well as china cold storage panel manufacturer—PROPANEL, is engaged to give the best products to customer.   The metal surface layers include steel sheet, aluminum plate, or stainless-steel sheet... Inspections verify material bonds and fire ratings with lab tests.   The paint types of metal surface offer customization: PE for basic protection, HDP for higher durability, SMP for higher weather resistance, and PVDF for longer color life. Panels go through roller coating in production for even finish. This step follows strict color matching. Final quality detection uses visual and machine scans to confirm paint adhesion and thickness.   Special shapes sandwich panels like triangles or circles satisfy unique needs. Molds shape panels during manufacturing for custom fits. These handles curved or angled designs. Production ends with load tests and seal checks to confirm strength. Such special quality control ensures panels perform in all kinds of buildings’ roofs or walls.
