Since 1954, New England builders have trusted Reliable Truss, a division of National Lumber, for all their structural elements. We are experts in wood and steel trusses, structural components, and materials.

Reliable Truss manufactures Wood & Steel trusses and components. We design and manufacture commercial and residential roof trusses, as well as timber trusses, wall panels, floor panels, and I-Joists.

Find out more about our Wood & Steel Design and Manufacturing abilities from our brochure [PDF file, 966KB]. Reliable Truss also provides Custom Prefabrication — if we can ship it, we can build it.

We can design, manufacture, and ship prefabricated cupolas, dormers, pergolas, gazebos, and porticos. Find out more about our Custom Pre-Fabrication abilities from our brochure [PDF file, 1.24MB].
