Galvanized Steel Industrial Folding Door Space Saving For Large Opening Facilities
Factory-direct industrial bi-fold doors, electric folding systems and custom door solutions — engineered for warehouses, aircraft hangars, shipyards and logistics centers worldwide.
Trusted across 60+ countries by warehouses, aircraft hangars, shipyards, mining sites & logistics centers.
Lianxin Chitai is an industrial folding door manufacturer producing heavy duty bi-fold doors, electric folding door systems and large-opening custom solutions. Built on a galvanized steel frame with a multi-layer composite leaf and optional PU insulation, the doors support manual, motorized and PLC-controlled operation, resist high wind loads, and are supplied factory-direct with global shipping and ISO 9001 certification.
Unlike trading companies, we engineer and build every door in-house — so there is no reseller markup, lead time stays under our control, and a dedicated pre-sale team delivers shop drawings, wind-load calculations and installation guidance before you commit to an order.
A space-saving, high-cycle door engineered for the widest openings where sliding or sectional doors fall short.
Our industrial folding door system folds vertically or laterally along heavy-duty hinges, requiring minimal side room while clearing openings up to several meters wide. Each unit is built to order — from frame profile and panel skin to drive type and safety package — so it fits your building, not the other way around.
Leaves use a multi-layer composite construction: an aluminum or galvanized steel outer skin over an internal steel reinforcement frame, with optional polyurethane foam for thermal and acoustic insulation. The result is a rigid, weather-tight panel that stays square under wind and daily heavy use.
Every project begins with a site survey and engineering drawing, so clearances, wind zone and traffic frequency are accounted for before production starts — reducing on-site rework and commissioning delay.

Four reasons buyers specify folding doors over sliding or sectional alternatives for demanding sites.
Leaves fold flat against the wall, recovering the side clearance that sliding doors waste — ideal where space is tight.
Reinforced leaf frames span wide bays that sectional doors cannot, with stable operation at full width.
Balanced hinges and load-rated rollers keep daily heavy cycling smooth, quiet and low-maintenance.
Frame profile, panel skin, drive type and safety package are matched to your site, climate and traffic.
Three coordinated stages take the door from fully open to a tight, weather-sealed closure.
Hinged panels fold accordion-style, stacking compactly at the opening edge instead of sliding away.
Load-bearing rollers ride guided top and bottom tracks, keeping movement aligned and stable at full width.
Perimeter gaskets and a bottom sweep close the opening tightly against dust, wind and rain.
