Three-dimensional action
Loads are shared through an interconnected spatial grid, which can suit wide roofs and multiple support arrangements.
ZABALERALARGE-SPAN ARCHITECTURAL STRUCTURES
ZABALERA · STRUCTURAL SYSTEM
Space-Frame Structures
Multidirectional structural grids for wide clear spans, large roof areas and complex architectural geometry. Space-frame systems can distribute loads through a three-dimensional network rather than relying on a single line of primary trusses.
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.
Geometry flexibility
Flat, pitched, barrel, dome and more complex forms can be developed when the node and member system supports the required geometry.
Repeatable components
Modular member and node logic can support controlled fabrication, identification, packing and erection sequencing.
Architectural expression
The structural depth and grid can remain visible where the project wants the roof structure to become part of the architecture.
BEFORE SYSTEM SELECTION
Questions that materially change the structure.
01
Required clear span and support grid
02
Roof form and structural depth available
03
Design code and environmental loads
04
Suspended equipment and service loads
05
Envelope / cladding system
06
Corrosion and internal exposure
07
Transportable member / module constraints
08
Erection sequence and temporary stability
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.
