UL Certified Steel Fire Door with Unequal Leaves – YK Fire Rated Door Manufacturer

YK Door Industry Co., Ltd., a trusted name in fire protection systems, offers a superior solution for fire-rated entrance systems: the UL Certified Steel Fire Door with Unequal Leaves. This specialized UL metal fire door is engineered for both commercial and residential applications where performance and compliance are essential.

Built from galvanized steel sheets and filled with fireproof perlite board, our UL steel fire resistance doors combine fire containment capability with thermal and acoustic insulation. The powder-coated finish, along with a smooth heat transfer printed surface in rosewood, walnut, or oak grain, enhances the visual appeal of the door—without compromising on safety.

This model features an unequal leaf configuration, offering improved flexibility in spaces where asymmetrical openings are required. The smaller leaf allows everyday access while the larger one can be opened for equipment or emergency needs. The inclusion of fire-rated vision panels not only improves visibility but also maintains compliance with UL and WHI standards.

Our stainless steel fire doors, particularly those with vision panels and powder coating, undergo strict quality control to meet or exceed international safety certifications including UL, BS, WHI, and CCC. As a leading UL fire-rated door supplier, YK Door Industry prioritizes durability, safety, and customization.
