Johnson Bros offers many types of C Channels and Box Channels, including:
C Channel & Box Channel - Thickness & Length
C Channel & Box Channel thicknesses vary from .003" thick up to .150" thick. On 1/4 & 1/2 hard aluminum, Aluminum C Channel & Aluminum Box Channel thicknesses can reach up to .250" thick. Many different decorative pre-coated metals are generally not recommended when more than .030" thickness is required unless larger than normal corner radii can be used. Some coatings can be used, however, up to .125" thick such as a pre-finished Hot Dip Galvanized coating. Box Channel & C-Channel Lengths may be from 3" thru 40 feet long with close tolerances. Many different lengths can be put on one purchase order.
C Channels & Box Channels - Differences
C Channels are different than Box-Channels in the manner in which they appear in print, on Drawings, Sketches, and other images. C-Channels are shown with the opening or gap on the side of the image whereas on a Box Channel and Open Seam-Square or Rectangular Tubing, the opening or gap is on the top or bottom side as seen in the image. All of these 3 products are different names for the same part. Our Standard Sizes Chart on this page gives a summary of sizes with existing tooling that is available. The size chart gives dimensions, as they would be on a print with the opening or gap on the top or bottom, not on the side. With the part's image in this configuration, the sides are considered the legs and the width is considered the web. The flanges on both sides of the opening are considered the returns. Johnson bros has the capacity to manufacture the sides or legs up to 5" tall and the width can be as wide as 18" depending on the size of the legs and returns. There is a maximum raw material flat coil width of 19" that can be used. Inward flanges can also be added to the returns to turn the Box Channel into a Strut Channel or what is also called Framing.
