H-122-A

Name: H-122-A
Brand: Haydon

Overview

H-122 Back to Back Welded Channel - 2 Pieces

H-122-A strut channels are manufactured by a series of forming dies or rolls, which progressively cold work the steel strip into the desired channel configuration. This method produces a cross-section of uniform dimensions within a tolerance of ±0.015" on outside dimensions.

12 Gauge Back-to-Back Welded Channel
4-7/8" x 1-5/8"
Weight/100 ft. - 508 lbs.

H-122-A is a heavy-duty welded channel capable of carrying heavy loads. This product is commonly used for heavy applications and supporting over long spans. It is available "slotted" or with several other pre-punched hole and weld configurations.

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%.
See Table 1 for additional technical data.

NOTES

Other materials, finishes, lengths, and configurations are available upon request. Please contact us for other product availability.
