Vicwest's G90 galvanized and AZ50 Galvalume steel siding is listed in a gauge range that depends on the selected profile.

The captured OSFM description for 8175-2436:0001 covers steel siding from 24 through 28 gauge. It identifies G90 galvanized or AZ50 Galvalume material and expressly makes the thickness range dependent on the profile. That qualification matters when comparing an order with the listing: the range does not establish that every profile is offered at every gauge.

OSFM groups these products under noncombustible materials. The useful specification check is therefore the combination of siding profile, steel coating and gauge, rather than the Vicwest name alone. Ask the supplier to identify that combination for the proposed siding and match it to the current GOVmotus description before ordering. A listed range helps identify the products to check; it does not select the particular profile or thickness for the project.
