FAQs

Can the door size and panel thickness be customized for specific projects?

Yes, we provide full customization services. You can specify the clear opening dimensions (width/height) and choose from panel thicknesses of 100mm, 150mm, or 200mm to match your specific insulation requirements and cold room wall thickness.

What is the benefit of the "half-buried" design compared to traditional surface-mounted doors?

The half-buried (flush-mount) design ensures that the door panel is partially recessed into the door frame. This creates a flatter surface with the cold room wall, saving external corridor space and significantly reducing the risk of accidental impact from forklifts or trolleys.

Is there a safety mechanism if a worker is accidentally locked inside the cold room?

Absolutely. Every door is equipped with a heavy-duty internal safety release device (emergency escape handle). This allows personnel to open the door from the inside with a simple push or turn, even if the door is padlocked from the outside.

How does the door prevent freezing and sticking to the frame in low-temperature freezers?

For freezer applications, we integrate a 220V self-regulating electric heating wire within the door frame. This prevents condensation from freezing and ensures the door remains easy to open at all times, even in deep-freeze environments down to -45°C.

What material options are available for the door surface panels?

We offer 304 Grade Stainless Steel for superior hygiene and corrosion resistance (ideal for food and medical industries) and high-quality Anti-corrosion Color Steel (PPGI) for standard industrial applications. Both options are durable and easy to sanitize.

How do you ensure the airtightness of the door over long-term use?

We utilize a dual-layer EPDM high-elasticity gasket system. EPDM is highly resistant to aging and maintains its flexibility in extreme cold. The dual-seal design creates a redundant barrier against air leakage, significantly reducing energy loss and compressor workload.

Can your hardware withstand high-frequency industrial opening and closing?

Yes. Our hinges and latches are made of reinforced zinc alloy with stainless steel core pins. They are engineered for heavy-duty industrial cycles, ensuring that the door panel remains perfectly aligned without sagging, even with the weight of 150mm thick insulation.

Are your doors compliant with international food safety standards?

Yes, our doors are designed to meet HACCP and international hygiene regulations. The use of CFC-free PU insulation, food-grade lubricants, and easy-to-clean stainless steel surfaces makes them ideal for slaughterhouses, food processing plants
