Steel fire doors with knock down frames are widely used for export project orders because they can reduce packing volume, support easier container loading and allow frame assembly on site. For contractors, developers, distributors and overseas project buyers, the door leaf, knock down frame, wall thickness, hardware preparation, opening direction, project labels, packing method and installation details should be confirmed together before production.

Fire door frames for concrete wall and masonry wall projects must match the wall thickness, rough opening size, installation method, fire rated door leaf, hinges, lock position, closer preparation and project hardware package. For contractors, developers and overseas project buyers, choosing the correct frame supplier is critical because a wrong frame profile can cause installation gaps, alignment problems, site cutting, delayed acceptance and extra labor cost.

Warehouse fire rated steel doors are used in storage areas, loading zones, logistics corridors, equipment rooms, electrical rooms, fire separation walls and emergency exit routes. For warehouse developers, contractors, logistics facility owners and overseas project buyers, the door leaf, steel frame, fire rating, opening size, hardware package, surface finish, project labels and export packaging should be confirmed together before production.

Factory fire separation zones require durable fire rated steel doors that can support higher fire resistance, heavy-duty operation, accurate frame matching and reliable project delivery. 120 minute fire rated steel doors are often used in production workshops, equipment rooms, electrical rooms, storage areas, utility rooms, chemical-related areas, fire compartment walls and emergency exit routes. For contractors, factory owners and overseas project buyers, the door leaf, steel frame, hardware, opening direction, surface finish, labels and export packaging should be confirmed as one complete project system before production.
