Steel – Hot Dip Galvanized after Fabrication In hot dip galvanization after fabrication (HDGAF), the finished part is immersed in a bath of molten zinc (ASTM 123). This method results in complete zinc coverage and a thicker coating than pre-galvanized or electro-plated steel. The zinc coating is typically 2.6 mils or 1.5 oz./sq. ft. of surface area. This is the coating of choice for applications where protection from severe corrosion is a design factor. Stainless Steel Type 304 and Type 316 stainless steel material in accordance with ASTM-A-240. Fiberglass For extremely corrosive areas, Atkore offers the most complete line of fiberglass cable trays available. In addition, a full line of Aickinstrut and channel fiberglass products is available to support your full raceway installation.
Materials and Finish The material selection is based on the environmental conditions and economic considerations for the project.
Aluminum Aluminum material in accordance with AA- 6063-T6. Aluminum trays are suitable for most outdoor applications and offer reductions in total installed costs. Steel – Pre-Galvanized Hot Dip Mill-Galvanized steel (ASTM-A- 653-G90 CS) is zinc coated by a hot dip process. Steel strip from a coil is fed through a continuous zinc coater which cleans, fluxes and coats the steel with molten zinc. After cooling, the steel is recoiled. The pre- galvanized coating provides a total weight of 0.90 oz. of zinc for both sides of one square foot of material. Mill-galvanized ladder is made of pre-galvanized steel and generally used indoors or in locations not exposed to the elements or corrosives.
