Steel interior doors have become a key feature in modern architecture. Clean lines, slim frames, and large glass panels look simple, but they require a high level of precision, both in design and installation. In this type of work, even a small measuring error can lead to high costs. After all, a steel frame is not easily altered on site!

That’s where the Proliner comes in.

 

The challenge of measuring steel doors

Compared to traditional doors, steel interior doors leave little margin for error. Frames are often minimal, openings are not always perfectly square, and installations usually take place in finished interiors where any mistake is immediately visible.

Manual measuring can be time-consuming and not always reliable, especially when dealing with:

• Uneven walls or floors
• Complex shapes or angles
• Renovation projects with imperfect structures

For steel door specialists, accuracy isn’t a bonus, it’s simply part of the job.

 

Digital templating with the Proliner

The Proliner offers a reliable and efficient way to measure door openings digitally. By capturing the exact shape and dimensions on-site, professionals can eliminate guesswork and reduce the risk of errors during production and installation.

With the Proliner, you can:

• Measure complex openings with ease
• Capture precise angles and irregular shapes
• Work directly from digital data in your production process
• Avoid rework and costly corrections on-site

This is especially valuable when producing custom steel doors, where every millimeter or less counts.

 

From measurement to production

One of the biggest advantages of the Proliner is the direct link between measurement and production. The data collected on-site can be used immediately in CAD software, ensuring a smooth workflow from templating to manufacturing.

This not only saves time but also improves consistency across projects, whether you’re producing a single door or managing multiple installations.

 

A smarter way to work

For companies working with steel interior doors, precision and efficiency go hand in hand. The Proliner supports both by simplifying the measuring process and delivering reliable results every time.

Instead of constantly checking measurements, fixing mistakes, professionals can focus on what they do best: creating high-quality, perfectly fitted steel doors.
