12 Gauge 1-5/8" X 1-5/8" 20'' Channel, ST304

Additional technical specifications, including 'Allowable Beam Loads', 'Allowable Column Loads', and 'Section Properties' can be found on the W200 Series Channel 12 Gauge 1-5/8" x 1-5/8" category page.

• Channels are manufactured by the cold roll forming process which produces cross sections of uniform dimensions within tolerances established by the Metal Framing Manufacturer's Association, Metal Framing Standards Publication No. MFMA-4.

• Steel used in the manufacture of channels conforms to the ASTM specifications under the Specifications tab below.
• Design is based on AISI S100-2016 "Specification for the Design of Cold-Formed Steel Structural Members." Maximum bending stress used in design is 25,000 pounds per square inch (PSI). This is based upon a virgin steel minimum yield stress of 33,000 psi cold worked to an average yield stress of 42,000 psi.
• Welds meet the performance requirements of section 4 of AISI S100-2016 "Specification for the design of Cold-Formed Steel Structural Members." All multiple sections of two or more single channels are resistance spot-welded approximately 2" to 3" (51mm to 76mm) on center.
