Product name
Alpine HS20 Truss Plate
Product description
The product is manufactured from a 20-gauge steel sheet that meets the minimum specified ultimate tensile strength (380 MPa) and minimum yield strength (275 MPa) requirements of ASTM A 653/A 653M, “Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process” SS Grade 275 steel, and galvanized with Z275 (G90) zinc coating. The product has an uncoated nominal thickness of 0.879 mm and is stamped with 0.0124 teeth per square mm. The teeth are 9.5 mm in length.

CCMC recognition
The Canadian Construction Materials Centre (CCMC) assesses compliance with Canadian building, energy and safety codes. We are the only construction code compliance service supported and operated by the Government of Canada. Trusted by over 6,000 regulators across Canada.
CCMC assessments are recognized by construction authorities across Canada:
| Alliance of Canadian Building Official Associations (ACBOA) |  |
| First Nations National Building Officers Association (FNNBOA) |  |
| Canadian Home Builders’ Association (CHBA) |  |
| Alberta Building Officials Association (ABOA) |  |
| Saskatchewan Building Officials Association (SBOA) |  |
| Manitoba Building Officials Association (MBOA) |  |
| Ontario Building Officials Association (OBOA) |  |
| New Brunswick Building Officials Association (NBBOA) |  |
| Nova Scotia Building Officials Association (NSBOA) |  |
The CCMC provides code compliance assessments to Canadian code requirements, consulting nationwide with construction regulators to elicit regional variations in code requirements as well as provincial and local interpretations. Users are advised to review the technical information presented in CCMC assessments when making approval decisions. Learn more about how the CCMC provides a unique service for Canada.
