Large Scale Fire Door Projects: Manufacturing and Delivery Process

Introduction

Fire door projects are different from ordinary door orders. A hospital, hotel, or airport needs hundreds of fire doors, each one matched to a specific opening, a specific fire rating, and a specific set of hardware. Delivery schedules are tied to construction milestones. A delay in one batch of doors can hold up an entire floor or a complete building handover.

For contractors and project managers, the question is rarely about a single door. It is about whether a manufacturer can deliver the whole project on time, to specification, and with the documentation required for inspection. This guide explains how a large scale fire door project moves from specification through manufacturing, quality control, and delivery to the site.

What Defines a Large Scale Fire Door Project

A large scale fire door project is defined less by the value of the order and more by the number of door units, the variation in specifications, and the coordination required. A 300-door hospital project with private rooms, corridors, plant rooms, and stairwells produces a long schedule of openings — each with its own dimensions, fire rating, hardware set, and finishes.

Typical large scale fire door projects include:

• Hospitals and healthcare facilities, where fire compartmentation is critical because patients cannot be evacuated quickly

• Hotels and resorts, which combine fire ratings with acoustic performance and interior finishes

• Institutional buildings — schools, universities, government facilities — with high-volume, standardized door schedules

• Industrial plants and warehouses with heavy-duty steel fire doors

• Mixed-use commercial towers combining office, retail, and residential sections

What these projects share is the need for project management, not just manufacturing. Each opening must be surveyed, each door coded against a schedule, and each delivery coordinated with the construction program.

The Fire Door Project Process

A large scale fire door project follows a defined process from enquiry to site delivery. Understanding this process helps contractors and procurement teams plan ahead and avoid common delays.

1. Specification and Review

The project starts with the door schedule. The contractor provides the architect's drawings and the door schedule, which lists every opening: dimensions, fire rating required, acoustic rating, hardware requirements, and finish. The manufacturer's engineering team reviews the schedule against the standard the project is certified under — UL, EN 1634, BS 476, or AS 1530.4.

This stage identifies mismatches before production. Door leaf thickness, frame profiles, intumescent seal requirements, and hardware compatibility are checked against the fire test certificate. Any deviation from the tested assembly is flagged and resolved here, not at the factory gate.

2. CAD Drawings and Sample Approval

The manufacturer prepares CAD drawings for each door type in the project. These cover leaf construction, frame details, hardware positions, and elevation views. For standardized projects, a set of approved drawings covers multiple openings; for bespoke openings, drawings are prepared individually.

Sample doors are produced and submitted for approval before full production begins. This is when finishes, hardware, and fitting tolerances are confirmed against the project specification. Approving samples early prevents costly rework during series production.

3. Raw Material Sourcing

Fire door manufacturing starts with material procurement. Steel coils, timber for fire rated cores, intumescent strips, hardware, and finishes must be sourced from certified suppliers. For fire rated products, the raw materials must match what was used in the certified test samples — substituting steel grades or core materials changes the fire performance.

Forward planning matters here. Lead times for some components, particularly certified locks and closers, can extend beyond the door's own production time. A manufacturer with established supplier relationships orders these components before full production starts.

4. Production and Assembly

Production follows the approved drawings. Steel fire doors are cut, folded, welded, and finished; the fire resistant core is fitted; the frame is fabricated to match. Timber fire rated doors use engineered cores and veneers. Throughout production, each door is tracked against the project schedule so that every opening in the schedule is accounted for.

Hardware is fitted at the factory where possible. Surface-mounted closers, hinges, lock bodies, and seals are installed and tested in the factory environment rather than on site. This reduces site labour, shortens installation time, and ensures the hardware configuration matches the tested assembly.

5. Quality Inspection

Every fire door batch is inspected before packing. Dimensional checks against the door schedule, hardware function tests — closing force, latch engagement, seal fit — and surface finish inspection. Fire testing is conducted on certified samples, but the duty of the factory inspection is to confirm every production door matches the tested sample.

For international projects, inspection is often witnessed by third parties — consultants, project surveyors, or government inspectors. Documentation accompanies the shipment: test certificates, material certificates, and a packing list matched to the door schedule.

6. Packing and Delivery

Large scale fire door projects are delivered in stages, synchronized with the construction program. Doors and frames are packed to survive transport and on-site storage. Steel doors are protected against scratching and corrosion; glass doors are crated; hardware is packed in labeled cartons matched to the door schedule.

Shipping options depend on project location and timeline. Sea freight is typical for international projects, with doors packed into framed wooden crates or containers designed for door transport. Air freight is used only for emergency or small replacement batches because of the cost. Delivery documentation includes a detailed packing list so site teams can verify the shipment against the schedule.

7. Site Coordination and Handover

The final stage is site delivery and installation support. Each batch of doors must arrive when the site is ready — not too early, when storage could cause damage, and not too late, when it holds up the program. The manufacturer coordinates shipping dates with the project manager's construction schedule.

After delivery, technical support covers installation queries, hardware adjustments, and any door that needs replacement. The manufacturer also provides the documentation required for handover and building inspection: fire test certificates, conformity declarations, and maintenance guidance for the fire door assets.

How to Select a Fire Door Project Supplier

The choice of supplier determines whether a large scale fire door project runs smoothly. A manufacturer who only supplies door leaves without engineering support, quality documentation, and delivery coordination leaves the contractor to carry the risk.

Why Qi'an Door for Fire Door Projects

Guangdong Qi'an Door Industry Co., Ltd. has supplied fire door projects for more than 20 years. The company is a manufacturer, not a trading company — it produces its own steel fire doors, wooden fire rated doors, and glass fire doors in an integrated factory, and manages the whole project process from specification to delivery.

Qi'an Door's engineering team reviews door schedules and provides CAD drawings before production. The company matches each project to the applicable standard — UL, EN 1634, BS 476, or AS 1530.4 — and provides fire test evidence for the complete assembly, including hardware.

Large scale fire door projects delivered by Qi'an Door include hospitals, hotels, university buildings, airports, and stadium facilities across Asia, the Middle East, Africa, and Oceania. Each project receives a dedicated production schedule, quality inspection records, and staged deliveries coordinated with the construction program.

For international buyers, Qi'an Door handles the export documentation: packing lists matched to the door schedule, test certificates, and inspection reports. The delivered documentation supports the building handover and regulatory inspection on site.

Conclusion

A large scale fire door project is a supply chain exercise as much as a manufacturing one. The doors must be specified correctly, produced to match certified test samples, inspected at the factory, delivered in stages matched to the construction program, and supported on site through handover.

The manufacturer you choose carries most of this risk. A factory with engineering support, certified test evidence, production capacity, and logistics experience transforms the fire door procurement from a coordination headache into a managed process.

For contractors and project managers planning fire door projects, working with a manufacturer who manages the full process — specification, production, inspection, delivery — reduces delays and keeps the building project on schedule.
