Modfloor
Explore our integrated flooring solutions - including C-Span and Modfloor engineered to work seamlessly alongside WeFrameIT frames and trusses across multilevel projects.
C-Span Flooring System
C-Span is designed to replace web or timber joists with an engineered steel solution that improves service integration, installation speed and floor performance across residential and commercial projects.
C-Span is a light weight flooring system designed to replace web or timber joists.
Manufactured utilising state of the art rollformers the system comprises both joists and perimeter frame with the joists sitting at the same level as the perimeter, achieving a full load transfer for multi-level dwellings providing strength and reliability.
C-Span is suitable for both residential and large scale multi-level residential or commercial buildings, producing dedicated C and U profiles of 250mm and 300mm. The same flooring system can also be utilised for deck applications. The C-Span machine's unique punching system provides provisions for easy installation of HVAC and MEP services, along with other electrical and plumbing services, without compromising joint or profile strength.
C-Span joists are pre-punched with service holes to provide sufficient space for electrical, plumbing and air-conditioning services within the joist. Our trucks are fitted with HIAB cranes with substantial reach so C-Span can be delivered to site without the additional cost of crane hire and, for most two level jobs, no crane is needed to load the joist as they are light enough to be man handled.
C-Span is the smart choice to replace timber or web joists for residential mid-floors, with floor materials screwed and glued to the joist to virtually eliminate squeaks.
C-Span engineered steel floors can be panelised on site then installed using a mobile crane, removing waste and reducing site working risks.
These allow services to be installed without having to modify the floor system, with flared service holes increasing strength and protecting services from sharp edges.
Manufacturing web floor joists is the longest, most costly and complicated part of roll forming for an LGS frame and truss manufacturer. Outsourcing the flooring to C-Span can free up precious run time of LGS rollformers and labour to increase production of frames and trusses without compromising quality.
WeFrameIT Modfloor
Modfloor is engineered for individual designs and built to reduce assembly time, labour intensity and long-term structural risk.
Every Modfloor unit is engineered and customised for individual designs.
Modfloor means no measuring, cutting or welding, offering substantial savings during construction.
Modfloor is up to one-third cheaper than traditionally built chassis, as it is simple to assemble with unskilled labour.
Modfloor is 40% to 50% lighter than a heavy cold rolled steel chassis.
Rapid Assembly Proof
Modfloor is manufactured from ZINMAG ZM310 steel, offering 7 to 10 times more corrosion resistance than standard GI steel and tested to ASTM B117-19 for corrosion resistance.
Modfloor offers corrosion warranties for modular chassis with up to a 50-year corrosion warranty and a 20-year structural warranty.
Modfloor strength has been independently tested, confirming minimal deflection under load.
WeFrameIT Modfloor Benefits
Purchase cost and assembly time are substantially lower than traditional purlin or hot rolled floor systems.
High tensile ZinMag ZM310 steel supports up to 50-year corrosion warranty and 20-year structural warranty options.
Joists connect into pre-punched bearer tabs with tek screws, reducing fabrication complexity.
Manufactured from 80% recycled steel and fully recyclable with reusable lifting brackets.
Custom designs support diverse foundation systems, flexible widths up to 5.5m, and lengths limited by transport.
Pre-punched service holes allow plumbing, electrical and air-conditioning runs during factory production.
Independent Testing
Testing data underpins specification confidence and helps reduce downstream rectification risk.
ZinMag ZM310 steel has been independently tested by a NATA laboratory to ASTM B117-19 for 2,000 hours, reporting no rust or delamination under test conditions.
Independent deflection testing confirms high-strength performance and supports cleaner install outcomes with less onsite rectification.
