Unistrut channels are accurately and carefully cold formed to size from low-carbon strip steel.
All spot-welded combination members, except P1001T, are welded 3" (76 mm) maximum on center.
Steel: Plain 12 Ga. (2.7 mm), 14 Ga.(1.9 mm) and 16 Ga. (1.5 mm); ASTM A1011 SS GR 33.
Steel: Pre-Galvanized 12 Ga. (2.7 mm), 14 Ga. (1.9 mm) and 16 Ga. (1.5mm); ASTM A653 GR 33.
Many Unistrut 1-5/8" (41mm) channel sections are available as curved pieces in both single and combination styles.
Standard lengths are 10 feet (3.05m) and 20 feet (6.10m). Tolerances are ±1/8" (3 mm) to ±1/2" (13 mm) to allow for cutting.
Special lengths are available for a small cutting charge with a tolerance of ±1/8" (3 mm).
All beam and column load data pertains to carbon steel and stainless steel channels. Load tables and charts are constructed to be in accordance with the SPECIFICATION FOR THE DESIGN OF COLD-FORMED STEEL STRUCTURAL MEMBERS 2001 EDITION published by the AMERICAN IRON AND STEEL INSTITUTE USING ASD METHOD
