Engineered for maximum load bearing capacity, the heavy duty reinforced hinge iron courtyard door handles extreme weights and stresses. The hinges are custom forged from cast steel (GS 20Mn5) with 30mm thick leaves, supported by tapered roller bearings to distribute loads evenly. Capable of supporting doors up to 1.5 tons, the hinge design includes adjustable shims to correct sagging over time. The door panel uses 8mm thick low alloy steel (Q390), with internal bracing formed by I beams or channel sections welded in a truss configuration. Surface treatments include a zinc nickel alloy electroplate (15μm) and two component polyurea coating (200μm), providing abrasion resistance and chemical protection. This door is used in industrial settings (shipyards, aircraft hangars), commercial facilities (shopping mall service entrances), or large scale residential projects, where massive gate structures require unparalleled hinge durability.
