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: 

Can one use pressure-treated lumber in metal plate connected truss construction? If so, are special plates or coatings required?

Question: 

As an engineer, I have noticed truss designers in some high wind states routinely using “Main Wind-Force Resisting Systems” wind pressure coefficients as opposed to “Components and Cladding” coefficients to design for wind uplift. A roof truss is not a main wind-force resisting system and would have to have a tributary area of more than 1000 sq. ft. before qualifying for the lower Primary Frame coefficients. In my experience this practice is routine.

Question: 

We have a local builder wishing to use floor trusses with a 2-hour assembly. I have shown him the 2-hour design on pages 17-27 of the second edition of SBCA’s Metal Plate Connected Wood Truss Handbook. Is this assembly UL approved? If so, what is the design number?

Question: 

I am a building designer on a salt storage building project. I would like to use metal plate connected wood trusses in the design. What should I specify for the metal connector plates?

Question: 

Is there a chart available on the allowable amount of deflection on floor trusses?
