Frequently Asked Questions

How much does model C-TR731 cost?

A price can't be quoted before measuring. The opening size and your finish, glass and lock choices directly affect the amount; the survey is free and is followed by an itemized quote. See steel door prices for details.

Can the C-TR731 be produced in a different color?

Yes — the color isn't fixed. The catalog shows honey walnut, but the finish is chosen per project; on the surface finish options page we cover which surface works best where.

How does the measuring stage work when ordering the C-TR731?

Frequently Asked Questions

What is the lead time for a custom villa door?

Production takes 20-25 days from the day the specification is approved. Custom detailing — carved cladding, oversized leaves, special glass — can extend that, and we confirm the date in writing before starting. Ocean freight time to the destination port is added on top.

How are steel doors packaged for sea freight export?

Each door is crated in a wooden case built to its own dimensions, with edge protection and corner blocks, then strapped to prevent movement inside the container. Full container loading is used for project quantities; single doors and small orders ship as groupage cargo.

What measurements do you need to quote?

The width, height and wall thickness of the rough opening, in millimetres or in inches — whichever your drawings use. Photographs of the opening from inside and outside help us confirm the swing direction and the frame detail. No site visit is needed.

Can you manufacture to imperial (inch) dimensions?

Yes. An opening given as 36 x 80 inches is manufactured to that dimension directly. Nothing is converted to a nearest metric size and rounded, so the door arrives at the size your drawing specifies.

Who installs the door at the destination?

Your own contractor. Every shipment includes an installation drawing and the frame fixing set, and the frame is designed to be set into the opening without special tooling.

What export documents travel with the shipment?

Commercial invoice, packing list and certificate of origin, plus whatever else the customs broker at the destination requires. Documentation is prepared before the container leaves the factory.
