A geometric pivot leaf divided by asymmetric fractured lines on a grey surface — that is what sets apart this pivot steel door, code TR348. There is no standard size — the door opening is measured during the survey and production follows that measurement.
Product Code: TR348
Surface Pattern and Finish
The door is configured as a single pivot leaf. The leaf surface is worked into a geometry of asymmetric fractured lines. The catalog color is grey.
A long stainless steel handle is used. The finish in the image is the catalog choice — a different cladding can be selected from the cladding options page.
The design language is defined as designer pivot.
Who Is This Model For?
It is chosen first and foremost for villa entrances and office and plaza entrances. The one-piece leaf presents a single unbroken surface from the outside. The leaf rotates on bearings set into the floor and the head frame, which makes dimensions possible that no hinge could carry. In return, it needs swing clearance both in front of and behind the door. The when to choose a pivot door page explains which entrances are suitable.
Measurement, Production and Installation
Production starts with measurements taken on site. How the door opening is measured is covered on the how measurements are taken page; material choices on the galvanized or DKP sheet steel and lock systems pages. This model's technical values are in the table below. After delivery, warranty and service coverage applies; see the care and lifespan page for protecting the finish.
Frequently Asked Questions
How much does the TR348 cost?
The price cannot be quoted before measuring. The size of the door opening and your cladding, glass and lock choices directly affect the total; the survey is free of charge and is followed by an itemized quote. See steel door prices for details.
Can the color of the TR348 be changed?
It can. Grey is only the finish in the photo, not a fixed choice — you can pick from the alternatives on the cladding options page.
How does the measuring stage work when ordering the TR348?
Measuring is our job. We record 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 can I order the TR348?
You can fill in the pre-order form on our site or call us on 0532 689 21 46. Mentioning product code TR348 in your request speeds the process up. You can browse other pivot steel door models on the pivot steel door models page.
