What is an RHS ST
Membrane Structure?
The MECANCO RHS ST Membrane Structure is a purpose-built, utility-first tensile roofing solution — engineered around Rectangular Hollow Section (RHS) steel primary members that deliver clean, inclined linear roof profiles across large, column-free spans.
Where architectural curvature is not the priority and functional performance is paramount, the RHS ST system offers an economical, structurally robust and highly versatile roofing solution that does not compromise on build quality, finish or engineering integrity.
The profile is intentionally linear and inclined — fixed edge membrane terminations, minimal structural members and a restrained architectural language that keeps the focus firmly on utility, spatial efficiency and multi-service integration.
Engineered for utility, built for performance where function leads and form follows with quiet confidence.
RHS ST Membrane Structures Designed for Versatility & Scale
The MECANCO RHS ST Membrane Structure is offered across a wide range of structural configurations engineered to adapt to diverse site conditions, operational requirements and large-span roofing demands.
Single / Double Sided Slope Inclined Roof Profiles
Clean, linear inclined membrane geometries designed for large utility spaces, side coverages and highly functional industrial or commercial environments.
Large Span Column-Free Configurations
Clear spans of 10 to 15 meters and beyond achieved on single-column post supports — eliminating internal obstructions while maximizing usable space.
Fixed Edge Membrane Systems
Structurally clamped membrane perimeters engineered to deliver taut architectural surfaces with defined edge detailing and weather-sealed performance.
Multi-Service Integration Variants
Structural framing designed to integrate glass facades, partition systems, false ceilings, water drainage provisions and complete MEP add-ons within the primary roofing structure.
Engineered for Large-Span Utility Infrastructure
The RHS ST system is MECANCO’s answer to environments where large-span, all-weather roofing is required quickly, economically and without unnecessary architectural complexity.
Large Span Industrial & Commercial Roofing
Column-free membrane coverage designed for warehouses, industrial facilities, logistics yards and commercial utility spaces.
Multi-Utility Facility Roofing
Flexible overhead infrastructure supporting diverse operational activities beneath a single, stable roofing envelope.
Glass Facade & Partition Integration
RHS primary structure engineered to function as the support backbone for complete glass facade systems and interior glass partitions.
False Ceiling & Interior Services
Structural grid utilised for false ceiling suspension, lighting systems, fans and integrated MEP service runs.
Water Drain Provisions
Integrated roof drainage systems embedded within the inclined membrane profile for efficient water management across the full span.
Engineered for Thermal Performance & Utility Efficiency
The RHS ST system is primarily specified with an opaque blackout membrane fabric — delivering superior UV reflection, heat reduction and complete light control for utility-focused environments where translucency is not a functional requirement.
Opaque Blackout Membrane
Primary specification fabric engineered for maximum shade, controlled interiors and enhanced thermal comfort across industrial and commercial roofing environments.
Superior UV & Heat Reduction
High-performance membrane surface designed to reflect UV exposure and minimise heat gain beneath the structure during extended daytime operation.
Full Interior Light Control
Opaque roofing system prevents unwanted light penetration, making it suitable for utility-driven spaces where controlled indoor environments are preferred.
Alternative Fabric Options
Additional membrane variants remain available where site conditions, project demands or client preferences require customised material behaviour.
Engineering Discipline Meets Cost Intelligence
The RHS ST is where MECANCO’s engineering discipline and cost intelligence come together most clearly. By selecting RHS steel as the primary structural member, we achieve a minimalistic yet highly capable structural profile — one that avoids the bulk and visual weight of conventional industrial shed construction while delivering comparable or superior structural performance.
Minimal Structural Expression
RHS steel enables a clean, lightweight visual profile without compromising span capability or long-term structural reliability.
Economical Without Generic Execution
Engineered to optimise cost efficiency while maintaining the architectural refinement expected from a premium roofing system.
Functional Without Industrial Bulk
A restrained design language that eliminates unnecessary visual heaviness commonly associated with traditional shed structures.
Intelligent Multi-Service Roofing
Designed for clients seeking large-span, all-weather roofing with integrated utility performance — without the premium of full architectural over-design.
