Begin with real dimensions
Record the opening, the adjacent wall condition and any floor level information that may affect the door interface.
Internal steel and glass doors
Made-to-measure steel and glass doors for distributors, contractors and architects. Compare the opening arrangements, review the project requirements and send a brief for UK trade supply.
A clearer route to specification
The opening, leaf arrangement, glazing pattern, frame finish and interface with the surrounding work should be considered together. That gives the project team one coherent basis for review.
Record the opening, the adjacent wall condition and any floor level information that may affect the door interface.
Consider movement through the room, furniture nearby and whether a hinged, sliding or paired-leaf arrangement fits the plan.
Use the glazing divisions and frame finish to support the wider interior rather than treating the door as an isolated object.
Useful enquiry information
A concise project pack helps separate confirmed requirements from items that still need discussion.

Product questions for the UK trade
Resolve the opening arrangement first. Then check the specification and supply scope before placing an order.
A hinged leaf needs a clear swing zone. A sliding leaf needs somewhere to travel when open. Paired French doors give two opening leaves, so consider both the everyday route and the wider opening. Send a marked plan if you are comparing options; the arrangement should follow the room layout rather than the photograph alone.
This range is described as steel and glass. If a project specification allows alternative materials, identify them explicitly in the enquiry so quotations can be compared on the same basis. Do not assume that similar-looking frames have the same construction or performance.
Dimensions, leaf arrangement, glazing, finish, hardware, quantity and delivery scope all shape the quotation. A door schedule with an identifier for each opening is useful for multiple units. Approximate dimensions are enough to start a conversation; final dimensions and technical details need to be agreed before production.
State any required rating or test standard in the enquiry. A glazed internal door is not automatically a fire-rated or acoustically rated doorset. Any performance requirement must be checked against documentation for the proposed complete assembly before it is specified or ordered.
Send the openings, project postcode and the decisions already made by the design team.
