Channel Dimensions :
Thickness and Length of Channels
Johnson Bros U-Channel & J-Channel thicknesses can range from .003" thick up to .150" thick. On 1/4 & 1/2 hard Aluminum, thicknesses may be as much as .250" thick. Many different decorative pre-coated metals are not generally 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. Standard Tooling is available for most sizes. Our Capacities on U Channels and J Channels are: Using up to .075" maximum thickness, Legs can be up to 5.5" O.D. High and Web widths can be up to 19" O.D. wide. Using up to .156" maximum thickness, Legs can be up to 4" O.D. high and Web widths can be up to 14" O.D. wide. Aluminum U Channels & Aluminum J Channels will have higher maximum thicknesses. |

Some additional tooling costs may be required for: Special Corner Radii, Amco Bronze needed for highly polished stainless steel that is not allowed to be coated with a protective strippable PVC Covering, Legs bent more or less than 90 degrees, and other more sophisticated forming requirements.
Lengths may be from 3" thru 40 feet long with close tolerances. Many different lengths can be put on one purchase order.
