Compare the offered configuration, not only the price
Two fire door quotations may look similar while covering different leaf construction, frames, hardware, glazing, finishes and documentation. Ask every supplier to quote against the same door schedule and specification. Separate optional items and exclusions so the commercial comparison reflects the complete installed opening.
Check evidence against the actual product
Request the applicable test reports, certificates or labels required by the destination project. Review whether the evidence relates to the proposed material, rating, size range, frame, glazing and hardware arrangement. A generic certificate should not replace confirmation of the exact configuration being supplied. The certificate and factory-record guide explains useful documents to review.
Evaluate engineering and communication
A capable supplier should identify missing handing, frame depth, wall condition, vision panel and hardware information before production. Compare the clarity of marked schedules and shop drawings, response time to technical questions and revision control. Good drawing control reduces the risk of producing doors from an outdated schedule.
Review manufacturing and quality controls
- Ask how incoming steel, cores, glazing and hardware are identified.
- Confirm checks for dimensions, handing, preparation and finish.
- Request sample inspection records or progress photographs where appropriate.
- Clarify how nonconforming items are corrected before packing.
Include packing and delivery in the comparison
Export projects need protected edges, labeled packages and a loading plan that matches the installation sequence. Confirm whether frames, leaves and hardware are cross-referenced by door mark. Also compare lead time, drawing approval milestones and the treatment of replacement parts. Ask who handles site questions, shortages or transit damage after shipment and what evidence is required for a corrective response.
Build a comparable quotation package
Send each shortlisted supplier the same quantities, sizes, ratings, hardware, finish, destination and required documents. Review the available fire-rated steel door options, then submit the schedule through the quotation form for a documented response.
Compare complete scope, not only unit price
When comparing door suppliers, make sure each quotation identifies leaf construction, frame profile, anchors, hardware preparations, finish, glazing, labels, packing and document scope. A low initial figure often excludes items needed to complete the opening.
Check the submittal and production workflow
Ask how the door schedule is converted into shop drawings, how changes are recorded and what approval controls the production release. This reveals whether the supplier can manage varied openings consistently.
Review delivery evidence
For overseas projects, confirm marking, packing, container loading, documentation and shipment records. The same opening marks used for quotation should be carried through packing and site installation.
Review factory capability and shipping and delivery records.
Useful quotation inputs
Provide the opening schedule, wall type, sizes, handing, performance requirement, hardware and finish information. This gives the manufacturer enough context to identify the correct door, frame and preparation before production.
