Roof Trusses
Our roof trusses provide safe, efficient, and economical solutions for domestic and commercial buildings. Manufactured to exacting standards using state-of-the-art timber engineering, they support complex roofscapes and comply with BS 5268: Part 3. Ideal for extensions, housing developments, and industrial projects, these trusses offer durability, cost-effectiveness, and rapid installation.
Floor Joists
easi-joist floor systems combine stress-graded timber chords with precision-engineered metal webs for superior strength and lightweight performance. These joists allow easy routing of services, reduced site waste, and improved thermal and acoustic insulation. Suitable for domestic, industrial, and commercial applications, they enable long spans without intermediate supports, cutting installation time and costs.
Bespoke Design
Our bespoke design service creates tailored roof and floor structures using Wolf Systems software. From small house extensions to large commercial developments, we translate architectural drawings into detailed, compliant designs. This service ensures optimal structural integrity, material efficiency, and adherence to client-specific requirements, with free quotations and technical support.
Engineered Timber
Sdra-engineered timber solutions, including LVL (Laminated Veneer Lumber), offer high strength, stability, and sustainability. These products resist warping, rot, and fire, with consistent mechanical properties for beams, trusses, and joists. Ideal for demanding environments, they combine environmental benefits with advanced performance, reducing material volume while maintaining load-bearing capacity.
Delivery Services
We provide efficient delivery of roof trusses and floor systems from our Airdrie and Aberdeen facilities to locations across Scotland, Scottish Islands, and Northern UK. Our logistics ensure timely, secure transportation of precision-manufactured components, minimising site delays and supporting project timelines for both small and large-scale developments.
Questions
Do roof trusses require treatment?
Treatment is generally not mandatory except in areas prone to insect attack. Our trusses use kiln-dried, stress-graded timber for durability.
What timber is used in trusses?
We use European Whitewood graded TR26, kiln-dried to 12% moisture content, ensuring structural integrity and compliance with UK standards.
Can I modify installed trusses?
Never cut or drill trusses without consultation. Alterations risk structural failure; we advise on feasible solutions to maintain safety and compliance.
How are bespoke designs handled?
We use Wolf Systems software to create custom designs from architectural plans, ensuring precision and compliance with building regulations.
What are the benefits of easi-joists?
easi-joists offer lightweight strength, service routing flexibility, reduced site waste, and improved thermal/acoustic performance over traditional timber.
Do you deliver nationwide?
Yes, we deliver across Scotland, Scottish Islands, and Northern UK, ensuring timely transportation of precision-manufactured components.
