Services
Roof Trusses
Custom-manufactured roof trusses engineered for strength and efficiency. Our prefabricated solutions reduce on-site construction time by up to 40% while maintaining full compliance with Eurocode 5 and UK Building Regulations. Sustainably sourced materials and precision manufacturing ensure consistent quality for residential and commercial projects.
Posi-Joists
British-engineered posi-joists combining timber chords with steel webs for superior load-bearing capacity. Open-web design allows seamless integration of plumbing and electrical systems while achieving spans up to 20 metres. Ideal for floors and roofs in both domestic and commercial construction applications.
I-Joists
High-performance I-joists featuring solid timber flanges and OSB webs for exceptional dimensional stability. Resistant to warping and twisting, these components enable longer spans with fewer supports, reducing material waste and accelerating installation for modern construction projects.
Design Services
Advanced 3D design solutions using Mitek Pamir software for precision-engineered timber systems. Our team provides build-ready layouts, structural calculations, and compliance documentation, ensuring seamless integration with architectural plans and site-specific requirements for complex construction projects.
Gable Panels
Prefabricated gable panels manufactured to withstand site-specific wind loads. Constructed with OSB3 board and breather membrane, these components accelerate construction timelines by enabling simultaneous installation with main roof trusses while maintaining structural integrity.
