SPX Advanced Steel Panel Wall Technology
The SPX system has been developed to satisfy building codes across North America referencing AISI S100-07 and CSA S136-07 as referenced in the building codes. This information is produced as a general reference to support building officials, architects, engineers, builders and installers with the specification of SPX in various residential and commercial applications.

Independent Validation
Underlying CFS engineering has been independently validated by Roger A. LaBoube, Ph.D., distinguished teaching professor, Department of Civil Engineering and director of the Wei-Wen Yu Center for Cold-Formed Steel Structures at the Missouri University of Science and Technology, as well as independent engineers in Ontario.  The base technology was validated by independent testing with ISO/IEC 17025:2005 A2LA accreditation.

Sold Certified
In Canada, the SPX system is supplied with a technical specification bearing a professional engineering seal for Ontario. In some U.S. jurisdictions, a local professional engineer may need to prepare design drawings for permit purposes. 

The SPX system is suitable for use as a structural load-bearing wall above or below grade for exterior or interior wall applications in residential and commercial buildings in compliance with Building Codes in Canada and the United States. Evolutiondeck Inc. can assist builders, engineers, architects, and designers with their specific design considerations.

SPX is made from galvanized sheet steel manufactured in compliance with ASTM A653/A653M-98 Z275 (G90), with a minimum substrate thickess of 1.4mm (16 ga., 0.055in) and minimum yield strength of 345MPa (50ksi).

Structural Loading
The SPX system satisfies structural performance requirements for uniform engineering axial load of up to 35,000 lbf per linear foot, determined using CUFSM semi-analytical finite strip method developed by John Hopkins University.) The SPX system satisfies structural performance requirements for lateral earth pressure from max. 7-ft backfill around foundation wall, based on 60 psf/ft depth acting at wall centroid.  

PJT exterior platforms may be field assembled onsite, or as pre-assembled panels. 

Thermal Performance (-15F to 70F; -26C to 21C)
THERM computer modelling and full scale field tests show no condensation risk.  A condition contributing to household condensation problems is excessively high humidity levels in the air within the home.  The normal indoor humidity range in winter is 15 to 50 percent.

Rule 12-516(2) permits the use of non-metallic-sheathed cable with metal stud construction using approved inserts (grommets) to protect the cable where it passes through the metal stud.
