BY-231 is the product code of the monolithic anthracite pivot door for glazed facades in our catalogue. Like every door we make, this model is produced to measure; no leaf is supplied from stock. The image shows an anthracite finish.

Product Code: BY-231

Leaf Surface

It is produced as a single leaf. The model has a monolithic leaf designed for glazed facades. The colour applied is anthracite.

The finish shown is the catalogue selection — a different cladding can be chosen from the cladding options.

The design language is best described as modern pivot.

Where Is It Used?

Hotel and showroom entrances and office and plaza entrances are this model's typical settings. Its single leaf layout fits standard-width entrances. The leaf turns on bearings set into the floor and the head of the frame; which makes sizes possible that hinges could never carry. In return, it needs swing clearance in front of and behind the door. The when to choose a pivot door page explains which entrances are suitable.

Measurement, Production and Installation

We take the measurements during the on-site survey — based on the door opening, not the existing leaf; the method is explained on the how to measure page. You can find this model's frame, leaf and lock specifications in the table below; the lock systems and galvanized or DKP sheet steel pages detail the options. After installation, the care and lifespan and warranty and service terms apply.

Frequently Asked Questions

What does model BY-231 cost?

We cannot quote a price before measuring. The size of the opening and your cladding, 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 BY-231 be produced in a different colour?

Yes. The anthracite finish shown is this model's catalogue selection; it can be produced in different colours with compact laminate, composite, marine plywood and wood veneer options. We compare the alternatives 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 are taken from the door opening, not the existing leaf — the method is explained on the how to measure 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.
