TR512 is a building entrance door model distinguished by a wooden composition of interlocking circle and ellipse geometry on a russet brown body. 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 russet brown finish.
Product Code: TR512
Surface and Glass Section
It is produced as a double leaf with side glass. The surface treatment is a circle-and-ellipse geometric wooden composition at the center. The surface is finished in russet brown.
The model includes generous clear glazing. The model is fitted with a curved stainless steel handle. Color, pattern, and handle choices can be adapted to your project; the options are compared on the cladding options page.
Where Is It Used?
It is chosen primarily for housing-complex blocks and apartment building entrances. It was conceived for wide openings: the side sections both span the width and bring light to the entrance. The difference between these two types is not only a matter of size; we detail it on the villa door vs. building entrance door page.
Production and Installation Process
Measurements are taken from the door opening, not the existing leaf; we walk through the process step by step on the how doors are measured page. Frame, sheet thickness, infill, and lock specifications are listed in the table below. Sheet steel choices are compared on the galvanized or DKP sheet steel page, and lock alternatives on the lock systems page. After installation, the care and lifespan and warranty and service terms apply.
Frequently Asked Questions
How much does TR512 cost?
We do not publish list prices, because every door is made to measure. The total depends on the size of the door opening and the cladding, glass, and lock you choose. After a free site survey, we provide a written quote itemized line by line; we explain what drives the price on the steel door prices page.
Can TR512 be produced in a different color?
Yes — the color is not fixed. The catalog shows russet brown, but the cladding is decided per project; on the cladding options page we cover which surface works best where.
Can the glass have a different pattern?
Yes. The glass shown 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 glass-free version is also possible.
How does measuring work when ordering TR512?
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 doors are measured page.
How do I get a quote for TR512?

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.
