BY-77 is the product code of the twin glass strip dark walnut double leaf pivot door in our catalog. It is not sold in stock sizes; your entrance is measured on site, and the leaf is built to that measurement. The photo shows a dark walnut finish.

Product Code: BY-77

Pattern and Color

The model is configured as a double leaf. The model features a leaf with twin glass strips. The color applied is dark walnut.

Cladding and hardware are not fixed; the door can be produced with any of the alternatives on the cladding options page.

The design language is modern pivot.

Suitable Entrances

It is chosen primarily for hotel and showroom entrances and wide-fronted detached homes. It was conceived for wide openings: the side sections both span the width and bring light to the entrance. Because a pivot system transfers the leaf's weight to the floor, it can carry a taller and heavier leaf than a hinged door. Since the leaf sweeps through space in front and behind as it turns, the entrance must accommodate this clearance — details on the when to choose a pivot door page.

From Measurement to Installation

Production begins with measurements taken on site. How the door opening is measured is covered on the how doors are measured page; material choices are on the galvanized or DKP sheet steel and lock systems pages. This model's technical specifications are in the table below. The maintenance steps that extend the door's life are on the care and lifespan page, and the coverage is on the warranty and service page.

Frequently Asked Questions

How much does BY-77 cost?

We cannot quote a price before taking measurements. The size of the door opening and your choice of cladding, glass, and lock directly affect the total; the site survey is free, and an itemized quote follows. See steel door prices for details.

Can I have this model in a color other than dark walnut?

Yes — the color is not fixed. The catalog shows dark walnut, but the cladding is decided per project; on the cladding options page we cover which surface works best where.

How are measurements taken for BY-77?

We take the measurements during the site survey; nothing is required on your part. Measurements are taken from the door opening, not the existing leaf — we explain the method on the how doors are measured page.

How do I get a quote for BY-77?

You can fill in the pre-order form on our website or call us on 0532 689 21 46. Mentioning the product code BY-77 in your request speeds things up. You can browse other pivot steel door designs 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.
