Why Suppliers Ask For Door Schedule Before Quotation
For fire rated glass door projects, a door schedule helps suppliers confirm door size, quantity, fire rating, opening direction, frame type, hardware and installation location before quotation. Without it, the quote may be inaccurate or incomplete.
Get QuoteWhy A Door Schedule Matters
Fire rated glass doors are not quoted only by glass size. A complete door system may include fire rated glass, frame profiles, seals, hinges, closers, locks, handles, panic bars and access control hardware. A door schedule allows suppliers to understand the full scope before pricing.
For contractors, sending a clear door schedule can reduce quotation errors, missing hardware, production changes and installation delays.
1. Door Size And Quantity
The door schedule should clearly list each door opening size, door leaf size and quantity. This is especially important when a project includes single doors, double doors, side panels or transom panels.
Door number or location code
Opening width and height
Single or double door type
Glass panel size
Quantity for each door type
2. Required Fire Rating
Different doors in the same building may require different fire ratings. A staircase door may need EI90, while an internal office partition door may only need EI30 or EI60. The door schedule helps suppliers match each door with the right fire rated glass system.
3. Opening Direction And Hardware
Door opening direction affects hinge position, closer selection, panic bar layout and access control design. If this information is missing, the supplier may quote the wrong hardware or leave key items out.
Left-hand or right-hand opening
Inward or outward opening
Door closer requirement
Panic bar requirement
Lock, handle or access control requirement
4. Frame Type And Finish
A door schedule should also mention whether the project needs steel frame, aluminum frame, slim frame or frameless design. Frame finish, color and profile depth can affect both price and production time.
5. Installation Location And Wall Type
Suppliers need to know where each door will be installed. Doors for corridors, staircases, escape routes, hospitals, hotels, offices, data centers and electrical rooms may require different system details.
Wall type and wall thickness should also be confirmed because they affect frame fixing and installation method.
What A Good Door Schedule Should Include
Door number or project location
Opening size and door leaf size
Quantity
Required fire rating
Single door, double door or side panel design
Opening direction
Frame material and finish
Hardware requirement
Wall type and wall thickness
Delivery schedule and installation area
Conclusion
Suppliers ask for a door schedule before quotation because it helps confirm door size, quantity, fire rating, frame system, hardware and installation details. For contractors, preparing a clear door schedule can make the quotation faster, more accurate and easier to compare.
