This steel extra-large folding door is a custom-made oversized steel door engineered with a high-strength reinforcement frame and imported large bolts. It ensures high flatness, superior anti-theft performance, and excellent air tightness.

Thanks to the built-in recessed handles and anti-collision blocks, the door panels are effectively prevented from crashing into each other during operation.
Steel Extra-Large Folding Door: Heavy-Duty Solution for Industrial Applications
This steel extra-large folding door is engineered for demanding environments such as factories, exhibition halls, and hydropower stations. Constructed with dual-side hot-dip galvanized cold-rolled steel plates (Baosteel/Ansteel origin), the door frame features a 1.5mm thickness while each leaf is made of 1.0mm steel for optimal durability. Its internal structure is reinforced with thickened galvanized square tubes, ensuring exceptional load-bearing capacity and resistance to deformation.
Customizable in size, the door supports add-ons like louvers for ventilation and an integrated access door for convenient pedestrian passage. Standard hardware includes stainless steel locks, reinforced heavy-duty hinges, and imported large interlocking bolts, guaranteeing secure operation and long-term reliability. The door’s honeycomb-infilled panels and robust hinges further enhance its structural integrity, making it ideal for high-traffic industrial settings.
