Custom Steel Roof Trusses for Wide-Span Roofs in Israel

t489-14

Custom steel roof trusses are engineered frames fabricated to the exact span, load and roof geometry of a specific building, allowing wide open spaces without intermediate columns. They are designed by a structural engineer, cut and welded to measure in our factory, then finished for durability and installed on site.

What Makes a Steel Truss Suitable for a Wide Span

A truss carries loads through a network of triangles, so each member works mainly in tension or compression. This is why steel trusses can cover wide distances with relatively light members, leaving the interior free of columns.

Span, roof slope, roofing material, snow and wind requirements, and any equipment hanging from the roof all influence the final shape. Before fabrication starts, these factors are confirmed with the structural engineer.

Our Process from Inquiry to Installation

Every project starts with your photos and a basic description of the building. We then visit the site to measure the openings and supporting walls, because existing dimensions are rarely exactly as drawn.

Materials and Finishes for Long-Life Roof Structures

Structural steel is chosen according to the span and loads, and the profile is matched to the engineer's calculation. Connections are designed to keep the truss straight and stable during lifting and over the years.

Roof trusses are exposed to weather and, in coastal areas, salty air. Hot-dip galvanizing gives strong corrosion protection, and powder coating can add the color and appearance your architect has specified.

Fabrication Accuracy and Quality Control

Wide-span trusses leave little room for error, because small deviations at the cut or weld become large gaps at the top plate. We cut members to length, check the geometry on the assembly area, and confirm that the truss matches the drawing before it leaves the workshop.

Where the building is not perfectly square, we can adjust connection points so the trusses sit correctly on the walls.

Installation Planning and Coordination

Lifting a long truss needs planning, including access for a crane, temporary bracing, and the order in which trusses and purlins are fixed. We recommend agreeing on these steps with your contractor early, so the roof can be closed quickly and safely.

Bearing points, anchors and wall connections should be checked on site before the trusses arrive.

Who Orders Custom Steel Roof Trusses

Our clients include private homeowners extending a house, building committees planning shared structures, contractors delivering commercial or residential projects, and architects and interior designers who want an open, visible roof structure.

If you already have drawings, send them with your inquiry. If not, we can work from your photos and measurements and prepare a specification for approval.

Frequently asked questions

How wide a span can custom steel roof trusses cover?

The achievable span depends on the truss depth, loads, and support conditions, so there is no single answer. The structural engineer confirms the maximum span for your specific building during design.

Do I need an engineer to approve the truss design?

Yes, a structural engineer should calculate and approve the truss design before fabrication. We work with your engineer to match the drawings to the calculated loads.

Can the trusses be galvanized for outdoor exposure?

Yes, hot-dip galvanizing is available and is a common choice for exposed roof structures. Powder coating can be applied over the finish if a specific color is required.

How do you measure the building before fabrication?

We carry out an on-site measurement of the openings, walls and bearing points. This ensures the trusses are made to the real dimensions of your building, not only to the original plans.

Common mistakes to avoid

Ordering trusses from rough sketches without site measurements is a common error that leads to misfit parts. Skipping the engineer's approval or choosing an unsuitable finish for the exposure can also shorten the structure's life.

Our recommendation

Share your photos, span and roof details early, and ask your structural engineer to confirm the loads before we start drawing. A galvanized finish is a sound choice for exposed roof steel, especially in coastal conditions.

Summary

Custom steel roof trusses let you cover wide spaces without columns, when they are designed by an engineer, measured on site and fabricated accurately to your building.
