Metal web joists are engineered structural framing components, typically combining high-grade steel webs with timber flanges. Designed as a lightweight alternative to solid timber beams or steel I-beams, they deliver long-span capability, consistent performance, and built-in service routes for pipes, cables, and ductwork.
Key Characteristics
• Structure: Parallel timber flanges connected by a galvanised steel plate web; available in standard depths and custom lengths.
• Span Range: Typically up to 12 metres, supporting floors, roofs, and mezzanines without intermediate supports.
• Benefits: High strength-to-weight ratio, reduced material usage, easier on-site handling, and prefabricated accuracy. Pre-punched web openings simplify service installation, speeding up construction and reducing costs.
• Performance: Manufactured to comply with Eurocode and UK building regulations; resistant to warping, shrinkage, and distortion; tested for structural integrity, fire safety, and acoustic performance.
Applications
• Residential housing developments, apartments, and social housing projects
• Commercial and industrial buildings, including offices, retail units, and warehouses
• Extensions, loft conversions, and modular construction
• Suitable for both new-build and renovation work
Design & Installation Notes
• Designed by qualified engineers using specialist software, tailored to load requirements, span, and building geometry.
• Installed in accordance with manufacturer guidelines and structural drawings; compatible with standard timber framing connections.
• Require proper bearing support, bracing, and protection from moisture and corrosion as specified.
Sustainability
• Manufactured from responsibly sourced timber and recyclable steel; efficient design reduces material waste and transport emissions.
• Longer spans enable flexible building layouts, supporting adaptable and future-proof structures.
