H-132-KO
Overview
H-132-KOH-132-KO strut channels are manufactured to precise specifications as 1⁵/₈" x 1⁵/₈" 12 gauge channels with knockouts.
With a weight of 194 lbs. per 100 ft., H-132 strut is the most common and typically the standard 12 gauge channel specified for a wide range of applications. Sometimes referred to as "deep" strut, it is widely used for MEP supports, trapeze installations, seismic bracing, and various other structural and support systems. It is available "slotted" or with multiple pre-punched hole and weld configurations to suit specific installation needs.

Specifications
Material
H-Strut channels are produced from prime structural metals covered by the following specifications. (See the technical section for additional information.)
- Aluminum (Type 6063-T6) - ASTM B221
- Plain Steel - ASTM A1011 SS Grade 33
- Pre-Galvanized Steel - ASTM A653 SS Grade 33, G90
- Stainless Steel (Type 304 & 316L) - ASTM A240
- Other materials and specifications are available upon request.
Finishes
H-Strut is available in powder-coated and zinc trivalent. Other finishes are available upon request.
- Hot-Dip Galvanized - ASTM A123
- Zinc Trivalent Chromium (ZTC) - ASTM B633
- Powder-Coated
Loading Data
- Load capacities in this section include a safety factor (to the yield strength) of 1.68 for beam loads and 1.80 for column loads.
- When calculating load at center of span, multiply load from table by 0.5 and deflection by 0.8.
- When calculating beam and column loads for aluminum, multiply by 33%.
Technical Information
H-132-KO strut channels are produced in standard 10' and 20' lengths with a tolerance of ±¹⁄₈".
Other lengths are available upon request.
