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.

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

Question: 

We are planning to add 1/2 in. cement board and 3/8 in. quarry tile to a kitchen floor. We need to know if the floor trusses will handle the additional weight. The floor trusses are 19.2 in. O.C. and the loading numbers are 40-10-0-5. What do these numbers mean?

Question: 

Are there any published studies or guidelines on the fire rating of floor trusses built with 2x3 lumber?

Question: 

I would like to know if there is an age restriction on wood trusses. How long after production are they safe to use? The trusses in question are at least three to four months old. Are they still safe to use? They have not been covered the entire time and are showing signs of age.

Question: 

I am installing a 40-foot scissor truss that is designed to deflect about ½ inch. I am concerned that the deflection will cause an interior partition wall to pick up some load from the truss and transfer it to the floor system. Should I double up the I-joists under this partition to pick up the extra load?

Question: 

What are the health hazards of black fungus on Douglas-Fir lumber?

Question: 

How do I, as a truss manufacturer, adequately advise my customer against the dangers of 60 ft. and over truss span installations?
