Marine Cold Storage Panels
Marine cold storage siding
The product panels are made of stainless steel sheet metal, available in either SUS304 or SUS316. The core is filled with high-density polyurethane foam, with a closed-cell ratio of ≥95% confirmed by third-party testing, ensuring long-term moisture resistance. The core foaming process is catalytically applied to a liquid mixture using a high-precision steel mold. After foaming, the foaming is allowed to mature for 24 hours to maintain a stable core density of 40-50 kg/m³, preventing shrinkage. Products are cut to length using a CNC panel saw with a blade speed of ≥3000 r/min, ensuring a perpendicularity tolerance of ≤0.3 mm/m. The bond strength between the panel and the core is ≥0.15 MPa, meeting the GB/T 10801.2 test standard. All products can be designed to meet customer requirements, ensuring prompt assembly and delivery. The panels utilize a "convex-concave groove" joint structure (female groove + male tenon). Stainless steel "anti-collision reinforcement strips" (2-3 mm thick) are added to the wall panels near the cold storage door to protect against forklifts and cargo impact.
