TR311 is a pivot steel door model defined by the wide stainless band that cuts across its black wood leaf. Like every door we build, this model is made to measure; we never supply an off-the-shelf leaf. The catalog finish is a black wood tone.

Product Code: TR311

Surface Pattern and Finish

The leaf structure is a single pivot leaf. The leaf surface is worked with a wide horizontal stainless band at its center. The finish is a black wood tone.

A recessed handle is used. The finish shown is the catalog choice — a different cladding can be selected from the cladding options.

Its design language is best described as modern pivot.

Which Entrances Does It Suit?

It is typically used for detached homes with wide frontages and hotel and showroom entrances. The one-piece leaf presents an unbroken surface from the outside. Because the weight rests on the floor rather than on hinges, the leaf can be far wider and thicker. As it needs swing clearance, it is not suited to narrow entrances that open directly onto a staircase; the when to choose a pivot door page lists the conditions.

Measurement, Production and Installation

Production starts with measurements taken on site. How the door opening is measured is covered on the how measurements are taken page; material choices are on the galvanized or DKP sheet and lock systems pages. This model's technical values are in the table below. After installation, the care and lifespan and warranty and service terms apply.

Frequently Asked Questions

What does model TR311 cost?

We can't quote a price before measuring. The size of the door opening and your cladding, glass and lock choices directly affect the total; the survey is free, and an itemized quote follows. See steel door prices for details.

Can the color of the TR311 be changed?

Yes, the color isn't fixed. The catalog shows black wood, but the cladding is decided per project; the cladding options page covers which surface works best where.

How is the TR311 measured?

Our survey team measures on site. If you'd still like to know the process, the how measurements are taken page explains the three points we measure.

How can I order model TR311?

You can fill in the pre-order form on our site or reach us on 0532 689 21 46. Mentioning product code TR311 in your request speeds things up. You can browse other pivot steel door models on the pivot steel door models page.

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.
