Large-Span Steel Truss Structures

Project-specific truss systems for halls, arena roofs, venue canopies and major clear-span buildings where directional primary structure provides an efficient and buildable solution.

WHERE IT FITS

Use the structural form where the project logic supports it.

No structural family is automatically the right answer. Geometry, loads, support conditions, architecture, freight and erection all affect system selection.

SYSTEM LOGIC

What this structural pathway can contribute.

Clear structural hierarchy

Primary trusses, secondary members and bracing create a direct load path that can be straightforward to analyse and coordinate.

Service coordination

Truss depth can create zones for lighting, AV, catwalks and selected building services when those loads are included early.

Fabrication flexibility

Welded and bolted assemblies can be developed around transport length, lifting capacity and site erection constraints.

Architectural range

Parallel chord, pitched, arched, tapered and other truss forms can respond to the roof and interior brief.

BEFORE SYSTEM SELECTION

Questions that materially change the structure.

Required span and truss spacing

Available structural depth

Support and bracing locations

Suspended equipment loads

Transport / shipping constraints

Site lifting capacity

Coating / galvanising strategy

Roof and drainage interfaces

TECHNICAL CONTROL

Span is an outcome of engineering — not a marketing number.

ZABALERA does not publish a single maximum span as though it applies to every structural family. Final practical span depends on system type, roof geometry, loading, structural depth, supports, service loads, environmental criteria, fabrication, transport and erection constraints.
