Custom Steel Stairs for Penthouse Projects | Techno Kol Uzi

t382-39

To order custom steel stairs for a penthouse, send photos and the floor plan to Techno Kol Uzi, where we measure on site and prepare a written drawing and specification for your approval. The stairs are then manufactured in our Tel Aviv factory, finished, and installed in your penthouse.

Why penthouses need custom steel stairs

Penthouse layouts are rarely standard. Floor-to-ceiling spans, double-height living rooms, rooftop access and terraces often leave little room for off-the-shelf solutions. Custom steel stairs let the structure follow the architecture, not the other way around.

Steel offers slim profiles, long clear spans and a light visual presence, which suits open penthouse interiors. Stairs can be designed as floating treads, open stringers or enclosed structures, depending on the look and the spatial needs of the project.

What to prepare before you order

A smooth order starts with clear information. Before contacting us, gather the following:

Floor plans showing the stair location and the height between levels
Photos of the space and any relevant design references
Preferred style, finish and handrail type
The construction schedule and the site access conditions

Having these ready helps us understand the project quickly and give you a realistic path forward.

Our order process, step by step

We follow a clear workflow so you always know where the project stands. First comes the inquiry, where you send photos and details. Next, our team visits the site for an on-site measurement. Based on those measurements, we prepare a drawing and a written specification.

Once you approve the drawing and specification, production begins in our factory. The steel is then finished, typically by hot-dip galvanizing or powder coating, and the stairs are installed on site.

Design, finishes and details

Every penthouse stair can be tailored in its details. Common choices include tread type, stringer design, balustrade style and the surface finish. Powder coating offers a wide range of colors, while galvanizing provides strong protection for demanding conditions.

Points to decide early

Decide on the tread material, the handrail height and whether the stair will be open or enclosed. Early decisions keep the drawing and production on schedule.

Safety and compliance

Stair and railing safety is an essential part of any penthouse design. Railings in Israel are governed by the standard SI 1142, and the exact dimensions, loads and clearances are verified with your engineer during the design stage. We work with your structural and safety requirements from the first drawing, so the final installation meets them.

If your project includes a building committee or a contractor, we can coordinate the drawings with their requirements.

Working with developers, architects and contractors

Penthouse projects often involve several parties. We regularly work alongside architects, interior designers and contractors, sharing drawings and adjusting specifications to fit the wider scope. Clear written specifications help keep everyone aligned, from design approval to installation day.

Our factory at 37 Rival Street in Tel Aviv has been run by the same family since 1945, and our team is available to discuss your project directly.

Frequently asked questions

How long does it take to get custom steel stairs made?

Lead time depends on the design complexity, the finish and the current production schedule. We confirm the timeline once the drawing and specification are approved.

Do you measure on site before making the stairs?

Yes. On-site measurement is a standard step, because accurate dimensions are essential for custom steel stairs that fit the penthouse precisely.

Can the stairs match my interior design?

Yes. We manufacture to measure and can adapt the tread type, stringers, handrails and finish to match your architect's or designer's vision.

Will you install the stairs in the penthouse?

Yes, installation is part of our process. We coordinate the installation with the site schedule so the work fits the rest of your project.

Common mistakes to avoid

Ordering stairs before the final floor levels and openings are confirmed often leads to costly changes. Sending incomplete photos or skipping the on-site measurement can also cause fit problems later.

Our recommendation

Involve the stair manufacturer early, ideally during the design stage, so the structure, railings and finishes are planned together with the rest of the penthouse.

Summary

Custom steel stairs for a penthouse are best ordered after on-site measurement and an approved drawing, so the design fits the space and the installation goes smoothly.
