Premium Quality Industrial Door Systems

Which industrial door system fits your facility?

• Hydraulic dock levellers — steel platform, hydraulic power unit, lip extension. For warehouses and cold stores with 8–12 truck movements per hour. Standard capacities: 6T, 8T, 10T. Platform widths: 1800–2400 mm. Lip extension: 400–600 mm. We build to your dock pit dimensions — not a one-size-fits-all box.
• Dock seals and shelters — mounted around the loading bay to close the gap between truck trailer and building wall. Reduces outside air infiltration by 70–90% depending on seal type and trailer fit. For temperature-controlled warehouses: keeps cold air in and humid outside air out. For food plants: keeps insects and dust out.
• Impact-resistant traffic doors — spring-loaded hinges or gravity self-recovery. Forklift hits it, door springs back. No manual reset. Available in PVC, aluminum-framed, or with food-grade surface finish. For high-traffic corridors (20+ passages per hour) between production zones, cold rooms, and dispatch areas.
• Cold storage access doors — insulated, gasketed, with heating elements around the frame to prevent ice buildup. For freezer rooms at -25°C and below. Available with vision panels, push-button or pull-cord operation, and emergency release.

All systems supplied with installation drawings, parts list, and torque settings for field assembly. You don't need to chase us for documentation after shipment.

What actual savings do you get from a proper dock seal?

At a -25°C freezer, an open dock without a seal lets in 200+ cubic meters of ambient air per hour during a typical 15-minute loading session. That air carries heat and moisture. The refrigeration system has to remove both — and that costs energy.

A properly fitted dock seal cuts that infiltration by over 70%. On a 10-dock facility handling 6 shipments per hour, the energy saving typically covers the seal investment within 8–12 months. We've seen this on cold store projects in Southeast Asia and the Middle East where ambient temperature is above 35°C for half the year.

Food safety: seals and shelters also keep out airborne contaminants. In meat and dairy processing, this is a regulatory requirement, not an option.

Factory-direct pricing and technical support

We manufacture dock levellers, traffic doors, and seals in the same facility as our cold room panels, compressor units, and evaporators. That means one factory — one quality standard — one point of contact for your entire cold chain equipment package.

Pricing: Typically 20–30% below European equivalents for comparable spec. No trading company margin. No third-party markup.

Lead time: 15–20 working days for standard dock levellers and traffic doors. Custom sizes or colours: 25–30 days.

Every unit: Hydraulic leveller test-run under full load (10T) before crating — we check lip extension, platform level, and hydraulic pressure holding time. Dock seals are pressure-tested at the joint points. You get a test report with each shipment.

For procurement teams and facility developers: We provide 2D pit dimension drawings, anchor bolt placement templates, and on-site installation checklists. Your contractor can install without back-and-forth clarification emails. For projects outside China, we supply export-worthy crating and shipping documentation.

What's the difference between a dock leveller and a dock plate?

Dock leveller — hydraulically operated, built into the dock pit. The platform raises, lip extends, and bridges the gap between dock floor and truck bed. Can handle uneven trailer floor heights (hydraulic adjustment). Supports forklift loading. 6–15 ton capacity. Permanent installation. Typical cost: higher upfront but lower maintenance and safer for operators.

Dock plate — portable steel plate that you lay across the gap manually. No hydraulic power. Lower capacity (2–5 tons). Workers move it by hand — ergonomic risk and slower turnaround. Suitable for low-volume, light-load facilities. Not recommended for cold stores, food plants, or distribution centres with daily forklift traffic.

Can your traffic doors handle forklift impact repeatedly?

Yes. Spring-return traffic doors recover from impact within 2–3 seconds. The PVC curtain or panel flexes, the hinge springs pull it back to closed position. For high-traffic corridors (e.g., between production and cold storage), we recommend the heavy-duty version with steel frame reinforcement and impact anchors. We've had customers in meat processing plants report doors lasting 5+ years with 40+ impacts per shift.

Do you supply doors and seals in custom colours?

Standard colour: RAL 5015 (blue) and RAL 9016 (white). Custom RAL colours available on order for dock levellers and traffic door frames. Note: custom colour adds 5–7 working days to lead time. Seals and shelters are available in black, grey, or white PVC/urethane — most customers choose black for dirt concealment in high-traffic dock areas.

What's your warranty on industrial door systems?

Hydraulic dock levellers: 2-year warranty on hydraulic cylinder and power unit, 1 year on platform structure and lip mechanism. Traffic doors: 12 months on springs and hinges, 12 months on PVC panels. We supply spare parts at cost for warranty claims — you don't pay retail for replacements.
