Custom Belgian Steel-Look Profile Windows Made to Your Measurements

t447-0

Custom steel-look profile windows are Belgian-style profile windows fabricated to the exact dimensions of your opening, so non-standard sizes fit cleanly without compromise. At Techno Kol Uzi, every unit is measured on site, drawn and specified in writing, then produced in our factory on Rival Street in Tel Aviv. This suits homeowners planning a new build who need odd openings or a consistent steel look throughout the house.

Why Choose Steel-Look Profile Windows

Steel-look profile windows give you the slim frames and dark, industrial character associated with traditional steel windows, combined with the practical performance expected from modern profile systems. The narrow sightlines let more light into the room and create clean, contemporary lines on the facade.

They are a good fit for homes with a modern or minimalist design language, and they pair well with other metalwork such as balcony railings, gates and handrails so the whole property feels coordinated.

When Standard Sizes Are Not Enough

New builds often include openings that do not match standard catalog sizes. Corner spaces, tall stairwell windows, wide living room openings and unusual proportions all call for a custom approach. Rather than adjusting the wall to suit a ready-made window, the window can be made to suit the wall.

Our Process From Inquiry to Installation

The process starts with an inquiry where you send photos and a rough description of the openings. We then arrange an on-site measurement, because accurate dimensions are the foundation of a good fit. Based on those measurements we prepare a drawing and a written specification covering profile, configuration and opening direction.

Once you approve the specification, the windows are produced in our factory. Finishing, including hot-dip galvanizing and powder coating where relevant, is carried out before installation, which we schedule so the work fits with the rest of your build.

Planning Your Windows Early in a New Build

The best time to plan custom windows is during the design stage, before the masonry and openings are finalized. When the architect and contractor know the window specification early, the frame dimensions, sills and lintels can be coordinated in advance, which avoids costly corrections later.

If your design is still being developed, share the drawings with us so we can review the openings and point out any details that need attention before construction reaches that stage.

Safety, Standards and Practical Details

Windows and any adjacent railings or guards must be designed with safety in mind, especially where openings sit close to floor level or balconies. For railings, the Israeli standard SI 1142 sets the general framework. Exact values depend on the specific location and design, so they are checked with the engineer on your project rather than assumed.

We also consider ventilation, operation style, hardware and glazing options so the window performs well in daily use, not just on the drawing.

Working With Architects, Contractors and Committees

We regularly work with homeowners, building committees, contractors, architects and interior designers. Clear written specifications make coordination straightforward, and having one manufacturer handle measurement, production and installation reduces the number of hand-offs on site.

If you are coordinating for a building committee or a group of units, let us know early so the specification can be consistent across all openings.

Frequently asked questions

Can you make windows for openings that are not standard sizes?

Yes. Every window is made to the measurements taken on site, so non-standard and irregular openings are a core part of our work. We confirm the dimensions and send a written specification before production begins.

Do I need to send drawings before you measure?

Drawings are helpful but not required. Photos and a rough description are enough to start the inquiry, and we then carry out an on-site measurement to confirm the exact sizes.

How are the windows finished?

Finishing depends on the specification and can include hot-dip galvanizing and powder coating. The finish is agreed with you at the approval stage, before production.

Can custom windows match other metalwork in my home?

Yes. Steel-look windows can be coordinated with balcony railings, gates, handrails and other elements we produce, so the finish and style feel consistent across the property.

Common mistakes to avoid

Ordering windows before the openings are finally fixed is the most common error, as late changes can force costly rework. Measuring from old plans instead of the actual wall on site also leads to fitting problems.

Our recommendation

Send your architect's openings list to the manufacturer early and ask for an on-site measurement before the masonry is closed. Confirm the specification in writing so the frame sizes, sills and finish are agreed before production starts.

Summary

Custom steel-look profile windows are the practical choice for new builds with non-standard openings, provided they are measured on site and specified in writing before production. Early coordination with your architect and contractor keeps the project on schedule.
