Metal Framing Channels - Cooper Industries

1 ChannelMetal Framing channel is cold formed on our modern rolling mills from 12 Ga. ( ), 14 Ga. ( ), and 16 Ga. ( )lowcarbon steel strips. A continuous slot with inturned lips provides the ability to make attachments at any & TolerancesAll Channels excluding SH style 1/8 ( )on 10 ( )and 3/16 ( )on 20 ( )All SH Channels only 1/4 ( )on 10 ( )and 1/2 ( )on 20 ( )Custom lengths are available upon series of Channels offer full flexibility. A variety of pre-punched slot patterns eliminate the need for precise fieldmeasuring for hole locations. Slots offer wide adjustments in the alignment and bolt variety of pre-punched 9/16 ( mm)diameter hole patterns are available in our Channels . These hole patterns provide aneconomical alternative to costly field drilling required for many used with series B217-20 Closure Strips, knockout Channels can be used to provide an economical listed surfaceraceway.

2 Channels are furnished with 7/8 ( mm)knockouts on 6 (152 mm)centers, allowing for perfect fixture alignment onspans up to 20 ( m).Materials & Finishes (Unless otherwise noted)Steel: Plain & Pre-galvanized12 Ga. ( ), 14 Ga. ( )and 16 Ga. ( )Note: A minimum order may apply onspecial material and Load (Steel & Stainless Steel)The design loads given for strut beam loads are based on a simple beam condition using an allowable stress of 25,000 psi. This allowable stress results in a safety factor of This is based upon virgin steel minimum yield strength of 33,000 psi cold worked during rolling to an average yieldstress of 42,000 psi. For aluminum channel loading multiply steel loading by a factor of spacing is maintained between 21/2inches ( mm)and 4 inches ( mm)on center. Through high quality controltesting of welded Channels and continuous monitoring of welding equipment, we provide the most consistent combinationchannels available dimensions are shown in parentheses.
