About Us
Calldene Group was formed in 2012 when two of the South East’s longest established and leading timber engineering brands were brought together.
Established in 1967, Dover Trussed Roof Company near Canterbury is one of the most experienced trussed rafter and metal web joist manufacturers in the South East of England.
For more than 50 years, Lancing-based Triad Timber Components has specialised in the design, production, and supply of structural timber components.
Together, under the Calldene Structural Timber Solutions brand, these businesses combine industry expertise and one of the region’s longest-standing structural timber design and manufacturing capabilities.
Dover Trussed Roof Company’s dedicated team of estimators, designers, and professional timber engineers use modern computer design technology to establish timber roof and floor structures that meet customers’ requirements. Dover Truss will supply design drawings to aid site erection and provide calculations for the local authority streamlining their processes. In addition, Dover Truss offers a comprehensive after-sales service, ensuring an exceptional experience for clients through project completion and beyond.
Triad Timber Components specialises in the design, production, and supply of structural timber components, which include Trussed Rafters, Posi Joist Roof & Floor System, and Timber Frame Structures. Triad also supplies a full range of associated metal fixings, laminated timber beams, and roof stability bracing.
To complement the design service, the package includes working drawings and design calculations to meet local authority requirements. Specialised erectors can also be arranged in conjunction with the design service to offer a complete ‘supply and fix’ service.
