7 (800) 521-9790 alpineitw.com CORROSION RESISTANCE Alpine offers three coatings for products that require extra corrosion resistance. Deterioration will occur more quickly when hangers and straps are exposed to corrosive environments. Products are available in the standard galvanized material or painted with SUPERSPEED ® gray paint. If you require additional protection, all parts are also available with G-Max (G185) triple zinc coating, hot dip galvanized coating or manufactured from stainless material. Fasteners used must also be considered when exposed to a corrosive environment. Please contact us for pricing and availability on these processes. Hot Dip Galvanizing: All products are available with a hot dip galvanized coating. This coating is applied after manufacture. The zinc content of the galvanization process is generally between 1.1 and 2.3 ounces per square foot of surface area. The actual thickness will vary with the material thickness of the part. This process provides extra protection for corrosive conditions. Stainless Steel: The best protection from adverse conditions is found in the use of stainless steel for manufacture. Type 316 stainless steel is used. It is recommended that stainless steel fasteners be used in conjunction with these specially manufactured hardware items. G-MAX Triple Zinc Coating: The standard coating requirement for ICC-approved connectors is (G60) .60 oz of zinc per square foot of surface area. The standard coating provided on all Alpine connectors is (G90) .90 oz. of zinc per square foot of surface area. This is a 50% increase over ICC galvanized requirements. G-Max (G185)—or 3 times the ICC coating requirement—is a triple zinc coating that is available on many items in the KCMP product line.

Both round and triangle holes must be filled in order to achieve these "max" values. Diamond-shaped holes are provided in some hangers for temporarily holding the fasteners to the joist or header during the installation process. They also can be used for optional nailing to increase uplift. Slotted holes allow easier nailing when placement conditions are tight. In some cases, slotted holes can be placed horizontally ("slant nailing") or vertically ("positive angle nailing"), depending on your requirements. Embossed holes are used on certain straps, enabling installation with a power-activated gun, allowing faster and less expensive installation. Specify "SS" SUPERSPEED ® after the callout to indicate the embossed hole pattern. Placement teeth are found in many fasteners to provide faster and easier installation. These teeth act to hold the connector in place during the installation process.
