What is a Dome & Barrel Vault
Membrane Structure?
At the heart of every dome and barrel vault structure lies one of architecture's most enduring and expressive forms — the arch.
At MECANCO, this timeless geometry is reimagined in tubular steel, where semicircular arched truss members are precision-fabricated into graceful, flowing structural frameworks that carry tensile membrane roofing across large, column-free spans.
The result is a structure that is simultaneously engineered for performance and sculpted for beauty — where every connection detail, every flange joint and every curved member speaks the language of architectural craft.
The arch, reinvented — where the oldest form in architecture finds its most expressive modern avatar.
The MECANCO Dome & Barrel Vault Range
Centre Pole Dome Structures
A single central column supports the entire dome, creating a dramatic tent-like form with a powerful central presence and a completely open perimeter.
Twin Sided Pole Dome Structures
Bilateral column support delivering balanced, symmetrical dome profiles ideal for elongated or rectangular plan footprints.
Tree Branch Inspired Structural Grid Domes
Structural frameworks inspired by organic tree branching — multi-branched, single-supported column systems creating intricate, nature-inspired truss geometries.
Multi-Branch Single Column Domes
A singular structural column fans outward into multiple branches, distributing loads elegantly while creating a striking visual statement beneath the canopy.
Barrel Vault Structures
Linear arched profiles extended along a longitudinal axis, ideal for pathways, walkways and elongated covered spaces.
Spaces Reimagined
Through Dome Geometry
Sports Arenas
Column-free large span domes for paddle courts, pickleball facilities and recreational sports halls.
Clubhouse Spaces
Architecturally refined dome canopies that elevate premium leisure and hospitality environments.
Terrace Roofing
Beautiful overhead shelter for rooftop dining, terrace restaurants and open-air lounges.
Landscape Shelters & Sit-Out Pavilions
Dome and vault forms nestled within landscapes, creating intimate sheltered retreats.
School Pathways & Walkways
Covered walkways with colourful tubular trusses bringing vibrancy and identity.
Building Connector Walkways
Covered passage links combining weather protection with architectural continuity.
A Signature Detail —
The MECANCO Connection
What distinguishes a MECANCO dome from a standard fabricated structure is the attention given to every joint, every flange and every member intersection.
Our workshop detailing ensures that the structural connections are not hidden or minimised — they are celebrated.
Individual flange connectors, precision-fitted tubular members and carefully resolved node points collectively give our dome structures a quality of finish that is immediately visible and permanently enduring.
