Door Assembly Design
Steel Door Leaf
The door leaf is manufactured from steel face sheets and an internal core configuration selected to meet the relevant project assembly requirements. Door leaf thickness and edge design are determined by the selected system.
Steel Frame
The steel frame is selected according to wall type, wall thickness, opening preparation and installation method. Frame, anchors and hardware reinforcement should be coordinated before production.
Hardware and Closing Function
Fire door hardware must be compatible with the complete door assembly. Self-closing and positive-latching functions are commonly required for many rated opening applications.
Select door leaf construction, steel frame profile, core, seals and finish.
Fabricate steel sheets, reinforcements, internal core and frame components.
Prepare hardware reinforcements, hinge locations, lock cut-outs and vision-panel opening where applicable.
Assemble, inspect, label and pack according to the approved project specification.
Important: Fire performance and code compliance must be confirmed for the complete door assembly, including the door leaf, frame, glazing, seals, hardware, label and installation method. Always verify local authority and project requirements before ordering.

FAQ
1. What is a steel fire rated door? It is a steel door assembly intended for a fire-rated opening. The door leaf, frame, hardware, seals and installation must be compatible with the specified tested and listed system.
2. Can this fire door be used in factories and warehouses? Yes. Steel fire doors are commonly specified for industrial buildings, warehouses, equipment rooms, service corridors and protected exit routes, subject to project requirements.
3. Can the door be supplied as a double leaf door? Yes. Equal and unequal double leaf configurations may be available where permitted by the selected fire door assembly and project opening requirements.
4. Can a vision panel be included? A vision panel may be possible if the fire-rated glass, glazing method, door leaf and other components are compatible with the required tested assembly.
5. What hardware is available? Available options may include hinges, closers, locks, panic bars, flush bolts, coordinators, kick plates, smoke seals and intumescent seals.
6. Does every steel door have the same fire rating? No. The required rating depends on project design, wall rating, opening location, building regulations and the complete listed door assembly.
7. Can the door color be customized? Yes. Primer finish, powder coating and custom color options can be selected according to the project finish schedule.
8. Can this door be installed in drywall or masonry walls? The frame and anchor system can be selected for different wall constructions, but final compatibility must match the approved door assembly and project details.
