Yumi steel
Product introduction
These structural panels feature a three-layer composite design:
External facings: High-tensile steel/aluminum sheets (0.4-1.0mm) with box rib trapezoidal profiling for enhanced load-bearing capacity (up to 200kg/m²).
Core material: Rigid polyurethane foam (PU) insulation (40-150mm thick) with closed-cell structure, delivering thermal conductivity of 0.022-0.025W/mK.
Bonding system: Continuous hot-press lamination ensures full adhesion between layers, achieving peel strength >150kPa (EN 14509).

Product advantages
☆Superior Waterproof Performance
PU sandwich panels feature a closed-cell structure that effectively blocks moisture absorption, preventing water leakage and corrosion for long-term durability in humid environments.
☆Excellent Fire Resistance
With B1-grade fire rating (EN 13501), these panels slow flame spread and resist high temperatures, enhancing building safety in industrial and commercial applications.
☆Premium Insulation Quality
The high-density polyurethane core delivers exceptional thermal insulation (R-value up to 3.5/inch), significantly reducing energy costs for temperature-controlled facilities.
Product application
These PU sandwich panels are ideal for industrial roofing, cold storage walls, warehouse partitions, and aircraft hangars, these structural panels provide load-bearing insulation, weather resistance, and fast installation for temperature-controlled environments.
