The diamond geometric walnut wood building entrance door, code TR502, is built with blue glass and a diamond-pattern wrought iron grille on a walnut body, topped by a wide transom window. Like every door we make, this model is produced to measure; no ready-made leaves are supplied from stock. The catalog finish is a walnut wood tone.

Product Code: TR502

Leaf, Glass and Transom

The door is arranged as a double leaf. The leaf surface is worked as a diamond/geometric wrought iron grille. The catalog color is a walnut wood tone.

The glazed section takes the form of two vertical panels of blue glass. A blue-glass transom window sits in the upper section. The model is fitted with long, straight stainless steel vertical handles. 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-classic.

Who Is This Model For?

It is typically used in apartment building entrances and residential complex blocks. Since the side sections widen the opening, it suits wide-frontage entrances rather than narrow ones — and brings daylight into the hallway. We compare the points where the two door types differ on the difference between a villa door and a building entrance door page.

Production and Installation Process

Production begins 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 sheet or DKP (cold-rolled) 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

How much does the TR502 cost?

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 TR502 be produced in a different color?

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

Can the glass in the TR502 be changed?

Yes. The glass in the image is this model's catalog finish; provided Şişecam 5+5 mm laminated glass is used, it can be produced in different colors and patterns. A version without glass is also possible.

Do I need to take the measurements myself?

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 order the TR502?

You can fill in the pre-order form on our site or call us on 0532 689 21 46. Mentioning the product code TR502 in your request speeds things up. You can browse other building entrance door models on the building entrance 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.
