Bespoke Steel Structures Designed to Your Site Requirements

t489-1

Custom steel structures are frames and load-bearing elements designed and fabricated to the exact dimensions, loads and conditions of a specific site. Techno Kol Uzi works from on-site measurement and a written specification, produces every component in its Tel Aviv factory, and installs it to match the architect's intent.

What Counts as a Custom Steel Structure

A custom steel structure is any steel frame built for one particular project rather than taken from a standard catalogue. This includes pergolas, canopies, mezzanine frames, steel stairs, support frames for facades and free-standing architectural elements. Because every project has its own spans, heights and fixing conditions, the design starts from the site rather than from a template.

For architects and contractors, the value lies in having one fabricator handle the steel from first sketch to finished installation, so that dimensions and details stay consistent throughout.

Information We Need to Start

A good structure begins with clear inputs. The most useful information includes:

Architectural drawings or sketches with key dimensions
Intended use and any expected loads
Description of the fixing surfaces, such as concrete, masonry or existing steel
Finish requirements and exposure conditions
Installation access and site constraints

Photos of the location help us see the context quickly, and an on-site measurement confirms the figures before drawing begins.

From Measurement to Approved Drawing

Once the site is measured, we prepare a drawing and a written specification describing profiles, connections, fixings and finishes. Nothing goes into production until the client approves these documents. This step gives architects and contractors a clear record of what will be built and allows changes to be made on paper, where they cost little.

Where structural calculations or engineer sign-off are required by the project, the drawings are prepared to support that review, and we coordinate with the responsible engineer.

Fabrication in Our Tel Aviv Factory

All components are cut, welded and assembled at our workshop at 37 Rival Street, Tel Aviv. Working in one controlled space allows us to check fit and alignment before anything leaves the factory. Connections are prepared to suit the fixing method agreed in the specification, and each piece is labelled so that site installation runs smoothly.

Because the factory has operated since 1945 and is run by the third generation of the family, we work with a practical, hands-on approach to steelwork.

Finishing for Durability

Finish choice depends on exposure and appearance. For outdoor structures we commonly use hot-dip galvanizing to protect steel against weather, followed by powder coating where a specific colour or texture is required. The combination gives long-lasting protection and a consistent look across all parts of the structure.

Tell us early about the finish you need, since it affects handling, transport and the sequence of fabrication.

Installation and Handover

Installation is planned around the site, the fixing method and the sequence of other trades. We check alignment, secure connections and confirm that the completed structure matches the approved drawing. For projects with tight timing, we agree on the delivery and installation sequence in advance so that the contractor can plan around it.

Any questions about the final fixings or structural details are checked with the responsible engineer before work is closed out.

Frequently asked questions

Do you design custom steel structures from my architectural drawings?

Yes. We work from your drawings or sketches and prepare our own detailed drawings and specification for approval. Where engineering review is needed, we coordinate with the responsible engineer.

Do you visit the site before starting?

Yes, we take an on-site measurement so the design matches the real conditions. This is a standard step before any drawing is made.

How do you protect steel structures used outdoors?

For exterior work we typically use hot-dip galvanizing, with powder coating added where a particular colour or finish is needed. The right choice depends on the exposure of your site.

Can you work with contractors and building committees as well as architects?

Yes. We regularly supply contractors, building committees, interior designers and private homeowners, and we adapt the level of documentation to what each party needs for approval.

Common mistakes to avoid

Leaving the site measurement and finish choice until late in the project often causes redesigns and delays. Settle dimensions, loads and finish early so that drawing and fabrication can proceed without interruption.

Our recommendation

Send your drawings and a few site photos at the start, and ask for the written specification to be approved before production begins. This single step prevents most mismatches between design intent and installed steelwork.

Summary

Custom steel structures are designed from your site and drawings, fabricated in our Tel Aviv factory, and installed to match the approved specification.
