4.0 Channel Framing & System Components

4.1 Channel Framing Series 100 & 200

4.1.1  All fiberglass channels shall be manufactured using either vinylester
or polyester resin.  Resin selection must meet requirements of the StrutTech
chemical resistance chart.  Fiberglass channel sizes shall have polyester surface
veil over 100% of the surface to provide protection against degradation from
ultraviolet light.

4.1.2  All series 200 channel shall be supplied with integral notches 1” on center. Notches shall be located on the interior flange to prevent slippage of pipe clamps and fittings after installation.  In lieu of notched channel, unnotched channel maybe used if the vertical channel sections supporting the horizontal piping are provided with stop lock hardware at each pipe clamp to prevent slippage.  Stop lock hardware combines a channel nut, bolt and mounting plate attached under the pipe clamp. 

4.2 Pipe Clamps

4.2.1  Adjustable Pipe Clamps shall be non-metallic and non conductive,
manufactured by the injection molded process using thermoplastic polyurethane. Maximum pipe diameter supported by adjustable clamps shall be 3 inches.

4.2.2  Glass Filled Fixed Pipe Clamps for pipe and conduit under 8 inches shall be non-metallic and non-conductive; manufactured by the injection molded process using thermoplastic polyurethane or polyester.  Resin selection must meet requirements of the StrutTech chemical resistance chart.  Fixed pipe clamps for pipe and conduit over 8 inches shall be thermoset vinylester fiberglass, and shal be manufactured by either hand laminations or resin transfer molded.  Injection molded parts for pipe and conduit sizes over 8 inches are not acceptable.

4.3 Channel Fittings & Post Bases

4.3.1 All channel fittings and post bases shall be made from glass filled polyurethane or polyester. Resin selection must meet requirements of the StrutTech chemical resistance chart.

4.4 Fasteners

4.4.1 All fasteners shall be made from one of the following materials: Glass filled polyurethane, vinylester fiberglass, stainless steel. Resin selection must meet requirements of the StrutTech chemical resistance chart.
