This steel door carries code C-TR730: a centered diamond geometry on a gloss orange walnut surface. Production begins after your order: an on-site survey comes first, and the leaf is then built to fit the door opening. The finish in the photo is gloss orange-red walnut.
Product Code: C-TR730
Classic Surface Craftsmanship
The model is configured as a single leaf. A geometric diamond embossing sits at the center of the surface. The surface is finished in gloss orange-red walnut.
A gold knocker is used. The finish in the image is the catalog choice — a different cladding can be selected from the cladding options page.
The design language is defined as classic modern.
Where Is It Used?
It is most often used for homes under renovation and flat entrances. The single-leaf format adapts directly to conventional door openings.
Production and Installation Process
Measurements are taken from the door opening, not the existing leaf; the how measurements are taken page walks through it step by step. Frame, sheet-steel thickness, infill and lock specifications are listed in the table below. The choice of sheet steel is compared on the galvanized or DKP sheet steel page, and lock alternatives on the lock systems page. After delivery, warranty and service coverage applies; see the care and lifespan page for protecting the finish.
Frequently Asked Questions
How much is the C-TR730?
We do not publish a list price, because each door is made to measure. The total is set by the size of the door opening and the cladding, glass and lock you select. After a free survey we provide a written quote broken down line by line; what moves the price is explained on the steel door prices page.
Can the color of the C-TR730 be changed?
Yes. The gloss orange-red walnut finish in the image is this model's catalog choice; it can be produced in other colors with compact laminate, composite, marine plywood and wood veneer options. We compare them on the cladding options page.
Do I need to take the measurements myself?
We take the measurements during the survey; nothing is required on your part. Measurements come from the door opening, not the existing leaf — the method is described on the how measurements are taken page.
How do I get a quote for the C-TR730?

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.
