Desert truss uses a minimum of 2x4 kiln dried lumber.

Machine Stress Rated lumber is sometimes used for top or bottom chords depending on the span and the type of load the truss is carrying.

Grades of 2x4 lumber:

1) Stud (91) Hem/Fur (HF)

2) Number 2 (91) Spruce Pine Fur (SPF)

3) 1650 f1.5E MRL SPF

4) 2100 f1.8E MRL SPF

Grade of 2x6 Lumber

1) 1650 f1.5E MRL SPF

Grade of 2x8 Lumber:

About us

Below you will find some of the many truss types available.

The most popular trusses used in and around the southwestern United States are Common trusses with a 4/12 or 5/12 pitch.

Scissor trusses with a 5/12 pitch on top chord and 2.5/12 on bottom chord. Hip trusses along with corner jacks and open jacks to make up a Hip roof system.

Sloping Flat trusses with parapets for that Southwest style look.


Our Design Estimators, with the aid of Mitek engineering software, design each individual truss in your truss system.

The Engineered Drawings specify, design loads for top chord live and dead loads, bottom chord live and dead loads, maximum stress factors, deflection, minimum lumber grade, (see lumber grades above) spacing requirements, interior member bracing if required, connector plate sizes and locations, overall dimensions for length and height, heel heights and bearing points.
