Curtain Wall Fabrication: Design Support and Custom Metalwork

t503-16

Curtain wall fabrication is the custom production of the metal framing, brackets, and glazing components that make up a non-structural building facade. Techno Kol Uzi supports architects and engineers by producing to measured drawings, with finishing and installation coordinated from one workshop in Tel Aviv.

What We Mean by Curtain Wall Fabrication

A curtain wall is a facade system that hangs on the building structure rather than carrying loads itself. Its metal framing, mullions, transoms, brackets, and cover profiles carry wind and self-weight to the slab, while glass or panels fill the openings. Fabrication is the stage where these components are cut, drilled, welded, and assembled to the exact geometry in the drawings.

For architects and engineers, the value of a dedicated fabricator is precision on non-standard conditions: sloped sections, curved corners, irregular floor lines, and special joint details that off-the-shelf systems do not cover.

How We Support Design Development

We review the facade design early so that the metalwork fits the intent of the project. Our input typically covers profile sizes for the expected spans, connection details to the structure, thermal break positions, drainage paths, and how the frame will be sequenced for installation.

Clear written specifications for materials and finishes

Exact structural values, such as deflection limits and anchor loads, should be confirmed by the project engineer against the applicable standards.

Materials and Finishes

Curtain wall framing is produced in aluminum, steel, and stainless steel depending on the span, the corrosion environment, and the visual language of the building. Aluminum suits lightweight, slender frames. Steel gives higher stiffness for larger spans and steel-look profiles. Stainless steel is chosen for elements exposed to harsh conditions or where a bright, durable finish is needed.

Finishing options include hot-dip galvanizing for steel elements and powder coating in a range of colors, selected to suit the facade and the local climate.

Our Fabrication Process

Every curtain wall job follows the same disciplined sequence. The inquiry starts with drawings or photos, followed by on-site measurement where needed. We then prepare a written specification and drawing set for your approval. Only after approval does production begin in our factory on Rival Street in Tel Aviv.

Quality Control and Coordination

Accuracy is checked at each stage. Cut lengths, hole positions, and weld quality are verified against the approved drawings before any element leaves the workshop. Where the facade interfaces with other trades, such as glazing, sealants, and structural anchors, we coordinate dimensions in advance to limit site adjustments.

Clear labeling of each element, matched to the installation drawings, helps the site crew assemble the frame in the correct order.

Working With Architects, Engineers and Contractors

Projects run more smoothly when the fabricator is involved before the tender is finalized. We welcome early drawings, change requests in writing, and joint review meetings when the design is still flexible. Our clients include architects, interior designers, engineers, contractors, and building committees, and we adapt the level of detail to the needs of each party.

Please send the latest facade drawings, the elevation and section views, and any performance requirements, and we will respond with a practical review of the fabrication approach.

Frequently asked questions

Can you fabricate curtain wall framing to our own drawings?

Yes. We produce to the drawings and specification supplied by the design team, and we raise any fabrication questions in writing before production starts.

Which materials are available for curtain wall fabrication?

We work with aluminum, steel, and stainless steel, with finishes such as hot-dip galvanizing and powder coating. The best choice depends on span, exposure, and appearance.

Do you measure on site before fabricating?

Where the existing structure or openings need verification, we carry out on-site measurement before preparing the final drawings and specification.

Who confirms the structural design of the curtain wall?

The project engineer is responsible for structural values such as loads, deflection limits, and anchor design. We fabricate to those confirmed requirements and advise on practical detailing.

Common mistakes to avoid

Designers often finalize the facade concept without involving the fabricator, which leads to costly changes once production drawings are underway. Late changes to profile sizes or anchor positions also cause delays on site.

Our recommendation

Share your facade drawings and performance requirements with the fabricator at the schematic stage, and ask for a written review of the connection details before the tender documents are issued.

Summary

Curtain wall fabrication turns facade drawings into precise, finished metal framing, and early collaboration between designers and fabricator leads to better results on site.
