SELECTION NOTES

Compare the complete door set.

Ask for the specified construction and frame arrangement, rather than choosing from appearance alone.

Lock and hardware

Discuss cylinder or smart-lock preference, hinges, handles and destination compatibility.

Required performance

Tell us if the project needs a particular security, acoustic or weather-resistance test. Performance must be supported for the quoted assembly.

Appearance
Selected design, finish reference and matching requirements.
Configuration
Door leaf, frame and hardware requirements for the selected design.
Order planning

Frequently asked questions

Can I start from my own design?

Yes. Share a drawing or reference photograph. Feasibility, materials and dimensions are reviewed before a specification is confirmed.

Are all catalogue designs in stock?

Catalogue and website designs are selection references. Availability, minimum quantity and production time are confirmed in the quotation.

How is pricing calculated?

Pricing depends on the chosen construction, dimensions, finish, hardware, quantity and shipment requirements. Ask for an itemised quotation for your configuration.

Can this be part of a larger door package?

Share the full door schedule or a list of categories. We can discuss coordinated sourcing and delivery arrangements for the order.

Planning a solid painted finish?

Custom colours are available. Share a RAL code or your own colour sample; the 12 swatches in our guide are examples only. Confirm the coating and physical sample for your selected product.
