Technical Features
🚪
Door Body
All panels are made of high-quality stainless steel, with a double-sided panel thickness of 0.8mm, fundamentally solving the disadvantages of bulky wooden or fiberglass cold storage doors, and wood that is not corrosion-resistant or moisture-proof.
❄️
Insulation
Inject 42kg/m³ polyurethane under high pressure into the mold cavity for one-time molding. EPDM sealing strip with high elasticity, low temperature resistance and corrosion resistance is used, which is anti-aging and friction resistant.
🏗️
Door Frame
Made of aluminum alloy, treated with cold bridge partitions. All flat surfaces and track connection points are formed in the factory to ensure absolute installation flatness.
