Product Performance

Trusses provide a cost-effective, responsive solution to concrete formwork.

An unusual design project gives this CM international exposure.

CM increases profit with pre-designed shear blocking panels.

One analytical tool that can help you consistently determine code compliance and reliable performance is the freely available wall calculator developed by the Applied Building Technology Group (ABTG). 

Innovative thinking and careful construction allowed Truss Craft to give a condemned structure new life.

Question: 

Are there any typical wood truss span tables for roofs and floors available? Standard framing details for use in preliminary design?

Question: 

How important is continuous lateral bracing in roof trusses? Is it detrimental to the roof integrity if it is missing?

Question: 

We are finding it difficult to design permanent diagonal bracing for scissors trusses. The truss is often only a few feet in depth, which does not provide adequate room for diagonal bracing. Has SBCA come up with recommendations for permanent bracing of scissors trusses?

Question: 

How do trussed roofs perform in long-term service? Are there any reports of rusting in the nail plates, rot/insect attack, do-it-yourself modifications, or condensation and ventilation problems in the attic?

Question: 

How do you evaluate whether a metal plate connected truss is still usable after exposure to fire? Are there any recommended tests?
