Steel Frame Mezzanines and Stairs for Penthouses

t480-12

A steel frame mezzanine adds usable floor area to a penthouse without expanding the building footprint, and a custom steel staircase connects it to the main level. Both are designed to measure, fabricated in our Tel Aviv factory, and installed on site after structural checks.

Why Penthouse Owners Choose Steel Mezzanines

Penthouses often have high ceilings and generous volumes that can feel underused. A steel frame mezzanine creates an extra level for a study, a reading nook, a guest bed or a lounge, while keeping the open feeling of the space below. Steel is slim and strong, so the structure takes up little visual room and lets light pass through to the floor underneath.

Because the frame is made to measure, it can follow the shape of your roof, the position of windows and the layout you already have in mind.

How the Design Process Works

Every project starts with an inquiry and photos of the space. We then measure on site, checking ceiling height, wall conditions, existing beams and access routes. Based on these measurements we prepare a drawing and a written specification covering the frame, the decking, the railings and the stair.

Clear decisions at this stage prevent changes later.

Choosing the Right Stair for Your Mezzanine

The stair is often the most visible element. Options include straight, L-shaped and spiral designs, each suited to different footprints and ceiling heights. Treads can be steel, timber or glass, and the balustrade can be slim steel bars or glass panels.

Stair geometry must be comfortable and safe to use daily. Railing heights and openings are checked against the Israeli railing standard SI 1142, and exact values are confirmed with your engineer during design.

Finishes and Materials

Steel suits many finishes. Hot-dip galvanizing protects the frame against corrosion, and powder coating provides a wide choice of colors and textures, from matte black to warm metallic tones. Steel-look profiles can echo the metalwork already in your home, such as windows or doors.

Discuss the finish early so it matches the lighting, flooring and furniture you plan to use.

Installation and Structural Considerations

A mezzanine places new loads on the building, so it must be checked by a structural engineer before fabrication. The engineer confirms how the frame connects to walls, columns or the slab, and what load the floor can carry. Our team installs the components on site once these checks are approved.

Planning installation access early helps avoid delays, especially in an occupied penthouse.

Start Your Penthouse Project

Send us photos of your penthouse and a few notes about how you want to use the new level. We will arrange an on-site measurement, prepare a drawing and a written specification, and only begin production once you approve. Our workshop at 37 Rival Street, Tel Aviv, has been run by the same family since 1945, and we build every piece to your measurements.

Frequently asked questions

Can a steel mezzanine be added to any penthouse?

Most penthouses can accommodate a mezzanine, but ceiling height, structure and access must be reviewed first. A site measurement and engineer's check confirm whether it is suitable.

Do I need an engineer for a steel mezzanine?

Yes, a structural engineer should review the design because the mezzanine adds loads to the building. Our team coordinates with your engineer during the process.

What type of stair works best with a mezzanine?

The best stair depends on available floor space, ceiling height and how often it will be used. Straight, L-shaped and spiral options can all be made to measure.

How is the steel protected from rust?

We use hot-dip galvanizing as a base protection, and powder coating for the finish and color. Together they make the steel suitable for long-term use.

Common mistakes to avoid

Ordering before measuring the space and checking the structure can lead to costly redesigns. Choosing a finish or stair style without considering how the mezzanine will be used also causes regret.

Our recommendation

Decide the use of the mezzanine first, then let that guide the stair type, railing height and finish. Involve your engineer early so the frame and connections are approved before production begins.

Summary

Steel frame mezzanines and stairs give penthouses extra usable space and a striking design when they are measured, engineered and built to your needs.
