Types of Channel
Channels are made with all types of metal, but the most popular Metal Channels are stainless channels, steel channels, and aluminum channels.
Most Common Industries where Channels are used
A Channel is used for almost all industries for any possible application such as in this brief summary of other Channel terms: Protective Edges, Holders, Covers, Framing & Frames, Inserts, Decoration, Trim, Cladding, Brackets, Tracks, Slides, Posts, Standards, Supports, Reinforcements, Stiffeners, Railings, Rims, Rings & Clamps, Purlins, Subgirts, Girts. (Many other styles of Roll Formed Profiles have these same descriptions, however.)
Additional Channel Information
Tooling for U & J Channels with Legs at 90 Degrees is most
common and rarely are there any tooling costs associated with these
providing it meets our minimum order requirements of 2,000ft except
on pre-production samples. Lower quantities with Lot charges can be
negotiated. Our Roll Die & Straightener Tooling is Adjustable
and can easily be changed or added to without cost . Our In-line
Cutoff Tooling has smaller, inexpensive inserts making any tooling
that we may have to make, (which is rare), very inexpensive and
it`s most often Donated. Johnson Bros. even has Existing Adjustable
Roll Dies that can Produce Hems on the inside or outside of the
legs on these U-channels & J-channels. U & J Channels with
other than 90 Degree bends with legs Tilted In or Tilted Out, may
require very little or no extra tooling as most of the tooling used
comes from a regular set of 90 Degree bend channel tooling and
standard hemming rolls. Hems are generally .250"-.125" and
sometimes smaller.
High Speed Roll Forming is available. Greater Length Tolerances
allow Faster Production however, our modernized length control
system allows normal production speeds at close tolerances as well.
Tolerances on legs and web of +/- .032 are common with +/- .005 and
sometimes less are possible. Highly Accurate Roll Straighteners and
Die Boosts allow for very straight parts without kinks from the cut
off operation.
