Steel Frame Greenhouse Structures Built to Order in Israel

t489-24

A custom steel greenhouse frame is a greenhouse skeleton fabricated to your exact dimensions, crop needs and site conditions instead of a standard catalogue kit. Techno Kol Uzi produces these frames in its Tel Aviv factory, after measuring on site and agreeing a written specification with you.

What a custom steel greenhouse frame includes

A greenhouse frame is the structural skeleton that carries the covering, whether glass, polycarbonate or film. Custom frames are designed around the footprint you have, the height your crop needs, the number of spans and the way you plan to ventilate and irrigate the structure.

Main posts and arched or straight rafters
Purlins and bracing for stability
Gutter and roof-vent supports
Door frames and end-wall reinforcement

Because every element is cut and welded to measure, the frame fits your plan rather than forcing your plan to fit a kit.

How we plan the design with you

The process starts with an inquiry, ideally with photos of the site and a rough sketch of what you want to grow. We then visit the site to measure levels, orientation and access, and produce a drawing and written specification for your approval.

Nothing goes into production until you have reviewed the drawing. This keeps changes cheap and avoids surprises on installation day.

Materials and finishing for a growing environment

Greenhouses are humid and exposed to sun, so finishing matters as much as the steel itself. We use hot-dip galvanizing for corrosion protection and can add powder coating where a specific colour or extra surface protection is needed.

For wet areas or fertilizer-heavy zones, we can discuss stainless steel fittings and fasteners with you during the specification stage.

Sizing for crop, climate and ventilation

Height, span width and roof pitch affect airflow, light and how easily you can work inside. A taller ridge helps heat escape, while a steeper roof sheds rain and snow loads more effectively.

Crop height and the equipment you will use
Prevailing wind direction on your site
Position of roof and side vents
Access for vehicles and carts

Structural loads and foundation details are checked with your engineer before final drawings are approved.

Production and installation

Frame sections are fabricated in our factory at 37 Rival Street, Tel Aviv, then finished and delivered for installation. Pre-fabrication means most of the cutting and welding is done under controlled conditions, which speeds up assembly on your land.

Our team can handle installation directly, or work with your contractor according to the agreed plan.

Choosing a steel greenhouse supplier

Look for a supplier who measures on site, provides a written specification before production, and explains the finishing options clearly. Ask how the frame will be anchored, how it will handle wind and loads, and who will supervise installation.

A supplier with a long track record in metalwork, operating since 1945, can usually advise on practical details that a catalogue cannot.

Frequently asked questions

Can you build a greenhouse frame to a non-standard size?

Yes. Frames are made to measure, so unusual footprints, odd angles and specific heights can all be accommodated. Send photos and approximate dimensions to start the discussion.

Do you measure the site before quoting or designing?

Yes, we visit the site to measure levels, orientation and access. The drawing and specification are based on those measurements.

How is the steel protected against rust in a greenhouse?

Components are hot-dip galvanized, and powder coating can be added for extra protection or a chosen colour. Specific fittings can be upgraded to stainless steel where conditions require it.

Do you install the frame, or only manufacture it?

We can install the frame ourselves or coordinate with your contractor, depending on what was agreed in the specification.

Common mistakes to avoid

Ordering a frame before confirming crop height, ventilation and access leads to costly changes later. Skipping the site measurement and specification step often causes fit problems on installation day.

Our recommendation

Decide your crop, equipment and ventilation plan first, then have the frame designed around them. Review the written drawing carefully and confirm foundation and load details with your engineer before production starts.

Summary

A custom steel greenhouse frame is designed and fabricated to your site and crop needs, with galvanized finishing and planned installation.
