Also searched as farm door, barn door and insulated agricultural building door.
A general-purpose farm and barn door built to close agricultural buildings tight against weather, dust and vermin — galvanized or insulated panels in sectional, roller or sliding layouts, sized for machinery access and made to last outdoors. Built to your opening, from prototype to full production runs.
One idea: a hard-working door for the whole farm — tough enough for daily machinery access, tight enough to keep grain, feed and equipment dry, and built to shrug off sun, rain and dust year after year.
Agricultural buildings ask a lot of a door: wide access for tractors and loaders, a weather-tight seal to protect stored grain and feed, insulation where animals or produce need a stable climate, and durability against sun, wind and dust with very little maintenance. A door bought for the wrong duty sags, leaks or rusts within a few seasons.
RAX builds agricultural doors to your exact opening in sectional overhead, roller and sliding layouts, with galvanized steel or insulated PU panels and the option of motorisation, personnel pass doors and ventilation. Every unit is validated to 100,000 cycles in the RAX fatigue lab and shipped with technical drawings and an English manual so your local builder can install it cleanly.
Cycle life of 100,000 cycles is validated in the RAX fatigue test lab. U-value 0.33 W/m²K is a marketing reference value for the insulated panel, not a door-set test result; thermal and wind performance are confirmed per project on the matching standard for your configuration.
Every door is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification. Each row states whether the value is RAX-measured, an industry-typical range, or per project.
| Parameter | Specification | Basis |
|---|---|---|
| Door Type | Agricultural / farm door (sectional overhead, roller or sliding) | Product definition |
| Panels | Galvanized steel sheet (0.4–1.5 mm); optional PU foam insulated core (40–50 mm). | RAX build |
| Thermal Performance | U-value 0.33 W/m²K (insulated panel reference value); door-set value confirmed per project. | Marketing value |
| Cycle Life | 100,000 cycles validated in the RAX 100,000-cycle fatigue test lab. | RAX-measured |
| Sealing | Silicone rubber perimeter seals; nylon PA66 track on sliding builds. | RAX build |
| Operation | Manual as standard; optional motor drive with RAX servo VFD and sensing. | RAX options |
| Wind Performance | Confirmed per project on the matching standard for your installed size and exposure. | Per project |
| Operating Range | Tested from −30 °C cold storage to +50 °C desert conditions. | RAX-tested |
| Colour / Finish | Full RAL custom (common RAL9006, RAL9010, RAL7016, RAL5010); wood-grain transfer optional. | RAX build |
| Max Opening | Custom to your opening — confirm feasible span on technical layout. | Per project |
Need a thermal or wind value evidenced for your build? We arrange the matching test data per project — see Compliance below for what is held versus arranged per project.
Validated substrates, processed in-house on an auto PU foam panel line and CNC punching / bending centre. No outsourcing of the structural parts.
General farm and estate buildings that need durable, weather-tight access.
Your builders get the full document set before the door ships — the same package our farm-builder and distributor clients rely on.
Certificates we hold today, and the project-specific test data we arrange against the matching standard. We state held versus per-project so you can tender honestly.
Rigorous 100,000-cycle fatigue testing, validated galvanized steel and aluminum alloy materials, and precision manufacturing — performed in-house, not outsourced.
Large industrial doors from prototype to container-load delivery. Start with an OEM sample and scale to container-load branded production.
Every agricultural door is built to your opening and your building. Send the clear opening size, the layout you need and whether insulation or a pass door is required (or site photos) and our engineers return a proposal, technical confirmation and lead time.
From custom engineering to container-load delivery — the document set your local installers need.
Warranty: door body 2 years · operator/motor 3 years · servo motor 5 years. Free spare parts within warranty (DHL/FedEx 5–7 days). Lead time: sample 7–15 days · standard container 12–20 days · custom first order 20–35 days.
It depends on headroom and traffic. Sectional overhead doors seal tightly and insulate well where there is headroom above the opening. Roller doors need the least ceiling space and clear the opening fully. Sliding doors suit very wide openings where a top-hung leaf can stack clear of the doorway. Send your opening size and building type and our engineers recommend the best layout.
Yes. Panels can be built with a 40–50 mm PU foam insulated core for grain and feed stores, workshops and climate-sensitive buildings, which also reduces condensation. The U-value 0.33 W/m²K figure is a marketing reference for the insulated panel; the door-set thermal value is confirmed per project on the matching standard.
Yes. Agricultural doors are sized for tractors, loaders and trailed equipment, with galvanized steel skins and silicone perimeter seals that keep out rain, dust and vermin. Wind performance is confirmed per project on the matching standard for your installed size and exposure, and the door is tested across a −30 °C to +50 °C operating range.
Yes. Every door is engineered to your clear opening width and height, or from site photos. Every door is built to your non-standard size, in any RAL colour. Our engineers confirm the feasible span and produce a technical proposal for approval before production.
RAX holds ISO 9001:2015, CE marking against EN 13241 (industrial door product standard) and EN 12453 (operator safety), plus SGS material reports and Product Liability Insurance. Wind and thermal class and AS/NZS 4505 / UL counterpart test data are arranged per project, not held as standing certificates.
Sample orders run 7–15 days, a standard container 12–20 days, and a custom first order 20–35 days (repeat custom orders 15–20 days). FOB ports are Tianjin and Qingdao; FCL and LCL are both supported.
Every order includes wiring diagrams, an English installation manual, FAI first-article confirmation and pre-assembly photos, a factory inspection report (speed, noise, insulation resistance, visual), the 100,000-cycle fatigue test video/report, and the CE Declaration of Conformity with the EN 13241 test report.
Send your opening size (W × H), the layout you need and whether insulation or a pass door is required. Our engineers reply with a proposal and lead time — no obligation.
