Overview

H-164 Back to Back Welded Channel With Slots

H-164-OSA strut channels are manufactured by a series of forming dies, or rolls, which progressively cold work the strip steel into the desired channel configuration. This method produces a cross-section of uniform dimensions within a tolerance of ±0.015" on outside dimensions.

14 Gauge Back-to-Back Welded Channel
1⁵/₈" X 1⁵/₈"
Weight/100 ft. - 196 lbs.
H-164 is the most common channel used for supporting conduit and other electrical systems. Sometimes known as "shallow" strut, it is available "slotted" or with several other pre-punched hole and weld configurations.
H-164-A is the most common welded back-to-back channel used for electrical supports and other light-duty applications. This product allows for attachment to both the top and bottom of the strut.

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 finishes. Other finishes are available upon request.

Hot-Dip Galvanized - ASTM A123
Zinc Trivalent Chromium (ZTC) - ASTM B633
Powder-Coated

Loading Data

Load capacities include a safety factor of 1.68 for beam loads and 1.80 for column loads.
When calculating load at the center of the 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-164-OSA strut channels are produced in standard 10' and 20' lengths with a tolerance of ±¹⁄₈".

Other lengths are available upon request.

The beam capacities shown above include the weight of the strut beam. The beam weight must be subtracted from these capacities to arrive at the net beam capacity.
Allowable beam loads are based on a uniformly loaded, simply supported beam. For capacities of a beam loaded at midspan at a single point, multiply the beam capacity by 50% and deflection by 80%.
The above chart shows beam capacities for strut without holes. For strut with holes, multiply by the following:
- OS by 88%
