Installation channels/strut


Material:
  • C-profile with serrated edges
  • Scale to assist installation/assembly/measurement
  • Slots for greater flexibility
  • Longitudinal swaging for greater strength
  • Riveted connections for double channels

Material/Finishes

Plain (PL)

Plain strut retains the original oiled surface applied to raw steel during the rolling process. The pickled and oiled hot rolled channel is composed of carbon steel conforming to ASTM A570 GR 33. The strut is ideal for field finishing (painting) after adequate surface preparation.

Pre-Galvanized (PG)

Pre-galvanized strut is manufactured using material produced by passing carbon steel sheets through a molten zinc bath in a process known as "hot-dip mill galvanization". The material conforms to ASTM A653 GR 33 with a zinc thickness of G90 or 0.9 ounces of zinc
per square foot. The channel is formed and slots are punched after the hot-dip process hence the name "pre-galvanized strut". Surfaces of the punched and cut portions are somewhat protected by the adjacent zinc plating which acts as a sacrificial anode minimizing corrosion of the raw edges. Though generally not recommended for outdoor environments, pre-galvanized strut can be used in dry, mildly corrosive atmospheres.

Green (GR)

Green polyester powder is applied electrostatically to the steel channel after fabrication and the strut is then baked for 10 minutes at
400° F. Salt Spray (Fog) testing has been conducted to verify the performance of the finish. The polyester powder coating, when tested in accordance with ASTM B117-73, resulted in a scribed 5% failure time exceeding 600 hours. Polyester coatings provide excellent UV resistance. Since the finish is applied after fabrication all surfaces are protected.

Yellow Chromate (YC)

Formed, hot rolled steel is electro-galvanize zinc plated to 12 µm. The strut is then dipped in a yellow zinc dichromate bath to provide a non-porous moisture and air barrier. The zinc dichromate conversion coat extends the life of the zinc plating. The coating conforms to ASTM B633-85 SC3, Type II. Since the finish is applied after the strut is cut, formed and punched there are no unprotected edges.

Notes:
  1. Based on simple beam condition using an allowablle design stress of 25,000 psi (172 MPa) with adequate lateral bracing.
  2. See page 195 for different load and support conditions.
  3. Above loads include the weight of the member. This weight must be subtracted to determine the net allowable load the beam will support.
  4. For beam loading capacity of slotted strut, use 85% of appropriate load from chart.
