U Channels are produced with All Types of Finishes, from Standard Commercial Quality Mill Finish to Bright Annealed and Mirror Finishes. We can also createย Steel U channelsย as well as many other metals with ourย Roll Forming Process.ย Contact usย and weโd be happy to adapt your specific needs.
Roll Formed U Channels & Hat Channels
U-Channels are a roll formed shape similar toย J-Channels, with the main difference being that their open sides are of equal length. U Channels (including Hat Channels) and J-Channels often require extra inline fabrication during theย roll forming process, all of which Roller Die can handle with our well maintained roll form lines.
Hat Channels, which are a type of U Channel, look exactly as their name suggests, like a top hat. The Hat Channel is composed of two outward flanges (theย brim), plus two vertical dimensions (the sides of the hat). Another description would be that Hat Channels are roll formed U Channels, with the bottom (or horizontal web) perpendicular to two vertical legs containing outward flanges. These flanges are also referred to as โwingsโ or โfins.โ
Our roll form machines provide a smooth, attractive finish, can hold extremely tight tolerances, and provide sharp contours. As always, our standard tooling library is available to help offset tooling costs and our expert engineers can manage any steel U Channels (including Hat Channels) dimensions not listed in our standard tooling lists.

U Channel: Tolerance Capabilities
- Cross-Sectional Standard Tolerances: +/-.031โณ
- Angularity: +/- 1 degree
- Straightness: Maximum Deviation of .015โณ/ft
- Twist: Maximum Deviation of 1/4 degree per ft
U Channel: Length Tolerances
