Production line and factory setup overview
Produces certified steel fire-rated door leaves and frames through sheet cutting/punching, bending, reinforcement and hardware preparation, insulated-core installation, welding/assembly, coating, hardware fitting, dimensional checks and fire-test documentation.
Recommended lowest-entry line configuration Do not claim a fire rating without a tested door-set design. Start with one certified or testable size/family and a complete frame, leaf, core, seals, hinges, closer and lock specification; independent fire testing governs the commercial product.
Production process and implementation sequence
- Approved door-set design release
- Steel sheet cutting/punching
- Bending leaf/frame components
- Reinforcement and hardware preparation
- Insulated-core installation
- Welding/assembly and seam control
- Coating/hardware fitting
- Dimension/operation/documentation release
Products, capacity and market fit
- Approve a physical sample and applicable standard.
- Launch with a defined product range and documented tool settings.
- Keep material and quality records for each batch.
- Steel fire-rated doors and frames - Door-set size, steel thickness, core, frame, hinges, seals, closer/lock, smoke control, coating, fire rating and installation detail - Hospitals, hotels, warehouses, schools, generators rooms and commercial buildings
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Sheet laser/shear/punch and press brake | Forms leaf/frame components | Certified design dimensions |
| Door/frame assembly jigs | Controls squareness and seam fit | Set-specific tolerances |
| Core/seal/hardware station | Builds functional door-set | Approved component list |
| Coating line | Protects steel surfaces | Coating thickness/finish |
| Door-set QC tools | Releases tested configuration | Operation/gaps/documentation |
Raw materials, utilities and factory requirements
- Galvanised/cold-rolled steel sheet, qualified fire core, hinges, locks, closers, intumescent/smoke seals, fasteners, coating and packaging
- Stable electricity, covered raw-material storage and protected finished-goods handling
- Guarded equipment, documented maintenance, essential spares and product-specific safety controls
Indicative low-entry investment and implementation plan
These planning ranges prioritize economical machinery, local labor and local civil works. Final pricing follows confirmed capacity, product specification, delivery terms and site conditions.
| Scope | Indicative range | Entry-plan note |
|---|---|---|
| Sheet cutting, bending and assembly cell | US$35k–140k | Small/medium door workshop |
| Core, coating, hardware and QC | US$30k–120k | Certified component scope |
| Freight, setup, fixtures and testing | US$25k–100k | Door-set validation required |
| Indicative total | US$90k–360k | Workshop and component inventory excluded |
