Product information

Product name

Alpine HS18 Truss Plate

Product description

The product is manufactured from an 18-gauge steel sheet that meets the minimum specified ultimate tensile strength (480 MPa) and minimum yield strength (410 MPa) requirements of ASTM A 653/A 653M, “Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process,” HSLAS-F Grade 410 (formerly known as HSLA B/II 410) steel, and galvanized with Z275 (G90) zinc coating. The product has a coated nominal thickness of 1.184 mm and is stamped with 0.0108 teeth/mm2. The teeth are 8.3 mm in length.
