BY-91 is the product code of the angled-frame walnut double-height entrance pivot door in our catalog. It is not sold in ready-made sizes; your entrance is measured on site and the leaf is built to that measurement. The image shows a walnut finish.

Product Code: BY-91

Pattern and Color

It is produced as a single leaf. The model has an angled-frame, double-height leaf. Walnut is applied as the color.

Color, pattern and handle choices can be adapted to your project; the alternatives are compared on the cladding options page.

Its design language is modern pivot.

Suitable Entrances

Office and plaza entrances and hotel and showroom entrances are this model's typical settings. Its single-leaf layout fits entrances of standard width. Because a pivot system transfers the leaf's weight to the floor, it can carry a taller and heavier leaf than a hinged door. As the leaf sweeps space in front and behind as it turns, the entrance must allow for this clearance — details on the when to choose a pivot door page.

From Measurement to Installation

We take the measurements during the survey — the door opening is the reference, not the existing leaf; the method is described on the how measurements are taken page. You will find this model's frame, leaf and lock values in the table below; the lock systems and galvanized sheet or DKP (cold-rolled) sheet pages detail the options. After delivery, warranty and service coverage applies; see the care and lifespan page for protecting the surface.

Frequently Asked Questions

How much is the BY-91?

There is no fixed price — since every leaf is built to measure, the total varies with the dimensions, the cladding and the lock you choose. After the survey we send a written, itemized quote. The line items are detailed on the steel door prices page.

Can the BY-91 be produced in a different color?

Yes, it can. Walnut is only the finish shown in the photo, not a fixed choice — you can pick from the alternatives on the cladding options page.

How are measurements taken for the BY-91?

Measuring is our job. We measure the clear width of the door opening, its height from the finished floor and the wall thickness; details are on the how measurements are taken page.

How do I get a quote for the BY-91?

You can fill in the pre-order form on our site or call us on 0532 689 21 46. Mentioning the product code BY-91 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.
