Unistrut post bases are designed to securely fasten strut channel to multiple surfaces, including concrete. Post bases provide stability to strut installation and are available in a variety of finishes and configurations.
FEATURES
- Material is 1-5/8" [41mm] wide x 1/4" [6mm] thick unless specified.
- Holes are 9/16" [14mm] diameter, 13/16" [21mm] center to edge on 1-7/8" [48mm] centers unless specified.
PRODUCT SPECIFICATIONS
Material
- Carbon steel – ASTM A1011-00 SS GR 33 or ASTM A1011-00CS Type B
Finish
- Z – Electro-Galvanized (standard finish): Electroplating deposits zinc on the surface of the steel by electrolysis from a bath of zinc salts. Recommended for relatively dry indoor use.
- G – GN – Green Powder Coat: A polyester powder coating is electrostatically applied after fabrication. The powder is then baked on creating a 1.38 to 1.77 mil [35–45 µm] thick coating. The hardness of this coating meets ASTM D-3363-74, the impact rating meets ASTM D-2794-93 and the gloss meets ASTM D-523-85. This creates a coating that is resistant to chipping, peeling and corrosion. Available in many colors by special order.
- HD – Hot Dip Galvanized After Fabrication: Fabricated product is dipped in molten zinc and is completely covered on all surfaces. Recommended for outdoor use. Coatings on FNW HD products meet ASTM A123/153. The zinc coating is typically 2.6 mils [66.0 µm ] or 1.5 oz. per square foot [0.46 kg per square meter] per side.
- S4 – 304 Stainless steel: ASTM A240 (Type 304)
- S6 – 316 Stainless steel: ASTM A240 (Type 316)
- 316 Stainless steel nuts – ASTM A276-03
- Y – Yellow zinc dichromate: A 0.5 mil [12.7 µm] electro-galvanized zinc plating meeting ASTM B633 SC1 Type III is applied to the surface of the metal. Yellow dichromate is applied over the zinc. This results in a yellowish gold appearance and acts as a nonporous barrier sealant that is corrosion resistant and can be painted.
