H-112-A

H-112 Back to Back Welded Channel - 2 Pieces

H-112-A 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 plus or minus 0.015", on outside dimensions.

  • 12 Gauge Back to Back Welded Channel 2-Pieces
  • 6-1/2" x 1-5/8"
  • wt./100 ft. - 626#

Materials

H-112-A strut channels are produced from prime structural steel covered by the following specifications.

  • Pre-Galvanized Steel - ASTM A-653
  • Plain Steel - ASTM A-1011-04-SS
  • Aluminum (Type 6063T6) - ASTM B-221
  • Stainless Steel (Type 304 & 316) - ASTM A-240
  • Other materials and specifications available on request.

Finishes

All H-112-A strut channels are stocked in pre-galvanized and powder coated Supr-Green. Some sizes are stocked in zinc trivalent chromium, PVC or hot dipped galvanized.

  • Hot Dipped Galvanized - ASTM A-123
  • Zinc Trivalent Chromium - ASTM B-633-85
  • Powder Coated Supr-Green - ASTM B-117
  • PVC Coating 40 ML Thickness - Available Upon Request

Loading Data

  1. When calculating load at center of span, multiply load from table by 0.5 and deflection by 0.8.
  2. When calculating beam and column loads for aluminum, multiply by 33%.
  3. 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.

# Bearing Load may limit load | ** Not recommended - KL/r exceeds 200

Notes:

  • 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%, OS3 by 90%, RS (9⁄16 holes) by 88%, RS-MOD (3⁄4 holes) by 85%, KO by 82%, OS2.5 by 86%
