External Steel Wind Trusses Securing Spans up to 12 Meters
Cold-formed galvanized steel wind struts provide structural stiffness, resisting 3,000Pa wind loads across monumental openings.
Engineered for industrial plants and logistics docks, our heavy-duty doors integrate vertical-lift tracks, windload struts, and 100,000-cycle springs for large-span openings.
Cold-formed galvanized steel wind struts provide structural stiffness, resisting 3,000Pa wind loads across monumental openings.
Engineered track geometries route panels flush against vertical walls, optimizing usable overhead space for cranes and high forklifts.
Integrated mechanical catch devices lock the door within 20mm of vertical drop upon cable failure, securing worker life safety.
High-carbon alloy springs undergo pre-stressing fatigue treatment to endure non-stop cycling without premature load degradation.
Specifying our commercial Wooden Door System guarantees your project achieves certified acoustic privacy, long-term HVAC energy savings, and rigid fire-rated life safety without aesthetic compromise.
