Heavy-duty lateral-sliding door systems for warehouses, factories, hangars & large-span industrial openings
The RAX Industrial Sliding Door is engineered for large-span openings where a laterally sliding panel system is the most space-efficient solution. Unlike sectional doors that curve overhead, sliding doors travel parallel to the wall line — making them the preferred choice for warehouses with limited headroom, aircraft hangars, shipyard buildings, and manufacturing facilities where ceiling space is occupied by cranes, ductwork, or sprinkler systems.
As a pure manufacturer since 1999 with a 11,000 m² production base and 20+ R&D engineers, RAX produces each sliding door to your exact opening dimensions — from a single unit, with no minimum order. Every door is factory-tested against a 100,000-cycle fatigue protocol and shipped with complete installation guides, wiring diagrams, and English manuals for your local installation team. [SOURCED — RAX claim]
Industrial sliding doors in the export market commonly span openings up to approximately W 10,000–12,000 mm for single-panel steel constructions. [ESTIMATE] For wider openings such as aircraft hangars (span classes from < 30 m to > 120 m per Wikipedia), multi-panel sliding configurations or specialised hangar door systems are engineered per project. [SOURCED] The EN 12424 wind load classification (Class 0–5) applies, with large exterior doors on exposed sites typically requiring Class 3–5. [SOURCED]
Any opening width × height, RAL color, panel profile (flat / ribbed / cassette / orange-peel), and glazing configuration. Large industrial doors from 1 unit, no MOQ. [SOURCED — RAX claim]
Every sliding door is validated against our in-house 100,000-cycle fatigue testing protocol — covering springs, rollers, tracks, and hardware — before dispatch. Test report and video included in the delivery package. [SOURCED — RAX claim]
Choose ground-track (heavy-duty, high-wind), top-hung cantilever (clean floor, no trip hazard), or bi-parting configurations. Track material: hot-dip galvanized steel 1.5–3 mm. [SOURCED]
CE to EN 13241 (industrial door) and EN 12453 (operator safety); ISO 9001:2015; SGS material reports; Product Liability Insurance. Fire rating EI60/EI120 available as capability per project (EN 1634-1 test required). [SOURCED — RAX claim]
PU foam core 40–50 mm thick for thermal performance. RAX marketing value U = 0.33 W/m²K (pending own EN 12428 report). Industry reference: sectional lift doors with 45 mm panels achieve R = 18.25. [SOURCED]
English manual + wiring diagrams; operators pre-set and tested before dispatch. Export packing: steel frame + pearl cotton + stretch film with clear shipping marks. [SOURCED — RAX claim]

Standard choice for warehouses and factories. Cost-effective, strong, and corrosion-resistant with zinc coating. Best for inland, dry-to-moderate environments. Surface: polyester coating in any RAL color. [SOURCED — RAX claim]
Lighter weight for manual-operate or high-cycle applications. Natural corrosion resistance. Suitable for coastal facilities and food processing plants where weight reduction matters. [SOURCED — RAX claim]
304 (~18% Cr / 8% Ni) for general food-grade and washdown environments (breweries, dairy). 316 (+2–3% Mo) for high-chloride / marine / chemical environments (seafood processing, coastal plants). Both withstand CIP cleaning at 80–90° C. [SOURCED]
For cold storage, temperature-controlled logistics, and energy-compliant buildings. Panel core density optimised for thermal performance. Available in all steel or aluminium skins. [SOURCED — RAX claim]
One solid panel slides laterally on a ground track or top-hung rail. Best for openings up to ~10–12 m width. Simple, reliable, minimal maintenance. Ideal for warehouse loading bays and factory partitions. [ESTIMATE]
Two panels part from the centre, each sliding to one side. Halves the wall-space needed per side. Suitable for openings 8–20 m+ where wall run-back space is available on both sides. [ESTIMATE]
Multiple panels stack behind each other for very wide openings. Used in hangar and shipyard applications. Requires detailed structural engineering and foundation load calculations. [ESTIMATE]
Ground-track: heavy-duty, handles high wind loads, suited for exterior hangar/warehouse doors. Top-hung cantilever: clean floor (no trip hazard), ideal for food/pharma and forklift-traffic areas. Selection depends on door weight, wind zone, and floor condition. [ESTIMATE]
Not sure which configuration fits your project? Send your opening width × height, wind zone, and duty cycle to our engineers — we’ll recommend the optimal configuration and provide technical drawings within 48 hours.

Wind load resistance classification (Class 0–5) and test/calculation methods. Class 5 = above 1,000 Pa (exceptional, by special agreement). Large exterior doors on exposed sites typically require Class 3–5. [SOURCED: baijiahao.baidu.com; antpedia.com]
Thermal resistance (U-value) test method for industrial doors. RAX marketing value U = 0.33 W/m²K is pending own test report to this standard. [SOURCED: antpedia.com]
Fire resistance test for door and shutter assemblies. Integrity (E) and insulation (I) criteria. RAX offers EI60/EI120 as a capability — actual classification requires EN 1634-1 test per project, classified to EN 13501-2. [SOURCED: sgsonline.com.cn]
RAX can support Australian (AS/NZS 4505) and North American (UL) counterpart test data for projects requiring local compliance. [SOURCED — RAX claim]
RAX custom-manufactures to any opening size — large industrial doors from 1 unit, no MOQ. For reference, single-panel steel sliding doors in the export market commonly reach ~W 10,000–12,000 mm. [ESTIMATE] For wider openings (aircraft hangars, shipyards), multi-panel telescopic configurations are engineered per project. Hangar span classes range from < 30 m to > 120 m. [SOURCED: jc68.com; Wikipedia] Share your opening width × height and our engineers confirm the feasible span with technical drawings.
Ground-track systems handle heavier doors and higher wind loads — ideal for exterior hangar and warehouse doors on exposed sites. Top-hung cantilever systems keep the floor clear (no trip hazard) — preferred for food/pharma facilities and high forklift-traffic areas. The choice depends on door weight, wind zone, and floor condition. RAX engineers will recommend the optimal configuration based on your site parameters. [ESTIMATE]
EN 12424 classifies wind load from Class 0 (no rating) to Class 5 (> 1,000 Pa). [SOURCED: EN 12424] Large exterior sliding doors on exposed sites typically need Class 3–5. [ESTIMATE] The achievable class depends on opening span, panel gauge, and structural reinforcement (mullions, heavier-gauge steel). RAX marketing claims “Wind Load Class 5 Certified” for the spiral high speed door range; for sliding doors, the specific EN 12424 class is confirmed per project based on your opening dimensions and site wind data. [SOURCED — RAX claim]
For most food-grade and washdown environments (breweries, dairy, general food processing), stainless steel 304 (~18% Cr / 8% Ni) is the standard choice and withstands CIP cleaning at 80–90° C. [SOURCED] For high-chloride or marine environments (seafood processing, coastal plants, chemical washdown), specify 316 stainless (+2–3% Mo) for chloride resistance. Avoid chloride stress corrosion cracking above ~60° C in wet insulated conditions. [SOURCED] RAX stocks both 304 and 316 grades. [SOURCED — RAX claim]
