Steel Window RFQ Checklist for Heritage Renovation Projects
2026-06-07 19:14Steel windows for heritage renovation projects must balance architectural appearance, structural performance, glazing requirements and installation conditions. A useful RFQ should help the supplier understand the original facade, required steel profile, glass specification, finish, hardware and project approval requirements.
1. Start with drawings and existing facade details
For renovation projects, the original window proportions, mullion pattern and frame depth often matter as much as the new product performance. Buyers should provide elevation drawings, opening dimensions, photos of existing windows, target style and whether the project requires heritage approval or visual matching.
For product references, review Steel Windows, Steel Doors and Fixed Partitions according to the project scope.
Steel window RFQs should include drawings, existing facade photos, glazing requirements and finish expectations.
2. Confirm profile, glass and performance requirements
Steel window appearance is affected by profile width, mullion layout, glazing bead, corner details and surface finish. Performance requirements may include thermal insulation, acoustic control, safety glass, waterproofing and wind load. The RFQ should clarify which requirements are mandatory and which are design preferences.
| RFQ item | What to confirm |
| Window design | Opening size, mullion pattern, profile style, inward/outward opening and fixed panels. |
| Glass and hardware | Glass type, thickness, safety requirement, hinges, handles, locks and seals. |
| Finish and installation | Powder coating, color, anti-corrosion treatment, packing, delivery and site installation condition. |
3. Include doors, partitions and hardware when the scope is broader
Many heritage or boutique commercial projects include steel doors, internal partitions, glass hardware and fixed panels in addition to windows. When the scope includes more than one product type, the RFQ should list each opening separately and clarify which items share the same profile, finish and hardware style.
If the project requires hinges, handles, locks or special glass accessories, include the Glass & Hardware requirement in the same quotation request.
For renovation scopes that include doors and windows, list each opening and hardware requirement clearly.
4. Compare suppliers by drawing review and fabrication control
Custom steel windows require drawing review, profile selection, fabrication accuracy, surface treatment and packing protection. Buyers should compare whether the supplier can support shop drawings, sample confirmation, finish matching and project delivery coordination. For heritage projects, communication before production is especially important.
