Paneled Classic Petrol Blue Steel Door C-TR721

A classic two-section panel on a petrol blue body — the most colourful model in the collection — that is what sets steel door model C-TR721 apart. Production begins after your order: first we carry out an on-site survey, then the leaf is built to fit the door opening. The image shows a petrol blue finish.

Product Code: C-TR721

Classic Surface Craftsmanship

The model is configured as a single leaf. The surface treatment takes the form of a classic two-section panel. The colour applied is petrol blue.

A silver knocker serves as the handle. The finish shown is the catalogue selection — a different cladding can be chosen from the cladding options.

The design language is best described as classic.

Where Is It Used?

Apartment flats and flat entrances are this model's typical settings. The single leaf layout adapts directly to conventional door openings.

Production and Installation

Measurements are taken from the door opening, not the existing leaf; the how to measure page walks through it step by step. 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 C-TR721 cost?

We do not publish a list price, because every door is made to measure. The final amount depends on the size of the opening and the cladding, glass and lock you choose. After a free on-site survey we provide a written, itemized quote; the steel door prices page explains what drives the price.

Can the colour of C-TR721 be changed?

Yes. The petrol blue finish shown is this model's catalogue selection; it can be produced in different colours with compact laminate, composite, marine plywood and wood veneer options. We compare the alternatives on the cladding options page.

Do I need to take the measurements myself?

We take the measurements during the survey; nothing is required on your part. Measurements are taken from the door opening, not the existing leaf — the method is explained on the how to measure page.
