Channel & Combinations
Metal Framing Channels
Channel
Metal framing channel is cold formed on our modern rolling mills from 12 Ga. (2.6mm), 14 Ga. (1.9mm), and 16 Ga. (1.5mm) low
carbon steel strips. A continuous slot with inturned lips provides the ability to make attachments at any point.
Lengths & Tolerances
All channels excluding ‘SH’ style ± 1/8” (3.2mm) on 10’ (3.05m) and ± 3/16” (4.76mm) on 20’ (6.09m)
All ‘SH’ channels only ± 1/4” (6.35mm) on 10’ (3.05m) and ± 1/2” (12.70mm) on 20’ (6.09m)
Custom lengths are available upon request.
Slots
Slotted series of channels offer full flexibility. A variety of pre-punched slot patterns eliminate the need for precise field
measuring for hole locations. Slots offer wide adjustments in the alignment and bolt sizing.
Holes
A variety of pre-punched 9/16” (14.3 mm) diameter hole patterns are available in our channels. These hole patterns provide an
economical alternative to costly field drilling required for many applications.
Knockouts
When used with series B217-20 Closure Strips, knockout channels can be used to provide an economical U.L. listed surface
raceway. Channels are furnished with 7/8” (22.2 mm) knockouts on 6” (152 mm) centers, allowing for perfect fixture alignment on
spans up to 20’ (6.09 m).

Design Load (Steel & Stainless Steel)
YZN
The design loads given for strut beam loads
SS4
are based on a simple beam condition using
SS6
an allowable stress of 25,000 psi. This
AL
allowable stress results in a safety factor
of 1.68. This is based upon virgin steel minimum yield strength of 33,000 psi cold worked during rolling to an average yield
stress of 42,000 psi. For aluminum channel loading multiply steel loading by a factor of 0.38.
Welding
Weld spacing is maintained between 21/2 inches (63.5 mm) and 4 inches (101.6 mm) on center. Through high quality control
testing of welded channels and continuous monitoring of welding equipment, we provide the most consistent combination
channels available today.
Metric
Metric dimensions are shown in parentheses. Unless noted, all metric dimensions are in millimeters.

Based on simple beam condition using an allowable design stress of 25,000 psi (172 MPa) in accordance with MFMA, with adequate lateral
bracing (see page 12 for further explanation). Actual yield point of cold rolled steel is 42,000 psi (289 MPa). To determine concentrated load
capacity at mid span, multiply uniform load by 0.5 and corresponding deflection by 0.8. *Failure determined by weld shear.

Based on simple beam condition using an allowable design stress of 25,000 psi (172 MPa) in accordance with MFMA, with adequate lateral
bracing (see page 12 for further explanation). Actual yield point of cold rolled steel is 42,000 psi. To determine concentrated load capacity at
mid span, multiply uniform load by 0.5 and corresponding deflection by 0.8. *Failure determined by weld shear.

Based on simple beam condition using an allowable design stress of 25,000 psi (172 MPa) in accordance with MFMA, with adequate lateral
bracing (see page 12 for further explanation). Actual yield point of cold rolled steel is 42,000 psi. To determine concentrated load capacity at
mid span, multiply uniform load by 0.5 and corresponding deflection by 0.8. *Failure determined by weld shear.

Based on simple beam condition using an allowable design stress of 25,000 psi (172 MPa) in accordance with MFMA, with adequate lateral
bracing (see page 12 for further explanation). Actual yield point of cold rolled steel is 42,000 psi. To determine concentrated load capacity at
mid span, multiply uniform load by 0.5 and corresponding deflection by 0.8. *Failure determined by weld shear.

Based on simple beam condition using an allowable design stress of 25,000 psi (172 MPa) in accordance with MFMA, with adequate lateral
bracing (see page 12 for further explanation). Actual yield point of cold rolled steel is 42,000 psi. To determine concentrated load capacity at
mid span, multiply uniform load by 0.5 and corresponding deflection by 0.8. *Failure determined by weld shear.

*Based on simple beam condition using an allowable design stress of 25,000 psi (172 MPa) with adequate lateral bracing (see page 12 for
further explanation). To determine concentrated load capacity at mid span, multiply uniform load by 0.5 and corresponding deflection by 0.8.
