With almost 20 years of design and fabrication know-how behind us,
DWB are experienced in meeting our customers needs. Our design
offices employ highly skilled staff, whose on-going software
development training ensures we are at the leading edge of the industry.
Using state of the art Gang-Nail Systems software, we can prepare full colour working drawings for many types of roof structure, from a self-build garage to multi-house developments.
Structural calculations are provided and plans include details on structural infill timber and builders metalwork. Our services include:
- Full Roof Designs
- Collateral Warranties
- Feasibility studies
- Site surveys to confirm production sizes and pitches
- Friendly advice on erection procedures
DWB production plants use tried and trusted machinery for high levels of accuracy and reliability, aided by a Quality Assurance scheme controlled by TRADA.
As members of the TRA (Trussed Rafter Association) we can supply the much acclaimed TRA Technical Manual (for a small charge) which helps customers specify and erect Roof Trusses correctly.
