Material: Channels are accurately and carefully cold formed to size from low-carbon strip steel. ꞏ Steel: Plain ꞏ 19 Gauge (1.0 mm) ASTM A1008 ꞏ Steel: Pre-Galvanized ꞏ 19 Gauge (1.0 mm) ASTM A653 GR 33 All nuts are manufactured from mild steel bars conforming to ASTM A1011 SS Grade 33. Fittings are made from hot rolled, pickled and oiled steel plate or strip and conform to ASTM A1011 SS GR 33. Finishes: Channels are available in: Perma-Green III (GR), electro-galvanized (EG), Pre-galvanized (PG), conforming to ASTM A653 GR 33 and plain (PL). Nuts are available in plain or electro-galvanized (EG) finish. Fittings are available in Perma-Green III, electrogalvanized (EG) with zinc electrolytically to commercial standards ASTM B653-G90 Type III SC1; or plain (PL). Standard Lengths: ꞏ P-6000 – 16 Feet (4.88m) ꞏ P-7000 – 10 Feet (3.05m) Tolerances are + " (3.2 mm) to + " (12.7 mm) to allow for cutting. Special lengths are available for a small cutting charge with a tolerance of ± " (3.2mm). ¹3⁄16" Framing System
Application: A unique half-size reduction of the 15⁄8" channel width series, this smaller channel size can be used to carry light loads economically in applications such as instrumentation, retail displays and light-duty laboratory supports. It also provides the flexibility found in all Unistrut ® framing systems.
