STEEL BENDING PROFILES: CHANNEL


Albina has the ability to bend both standard channels (designated as C channel) as well as miscellaneous channels (designated as MC channel), from the very small sizes to the very large sizes. In fact, Albina can bend all of the mill supplied sizes of all types of channel.


We have the ability to bend channel the easy way (against the weak axis) and the hard way (against the strong axis).


Standard channel and miscellaneous channel are specified in similar fashions. An example callout for standard channel would be C12x20.7#. The C indicates standard channel. The 12 (in inches) indicates the depth of the channel. The 20.7# indicates the pounds per foot for the channel.


Similar to wide flange and I-beam, channel can be bent with a number of different bending processes. The most common bending method is a roll bend or pyramid bends method. Straight material is inserted into the rolls; the rolls are then moved horizontally to put the desired radius into the material. The material can also be bent incrementally hot or incrementally cold. This is where small sections of material are bent at one time. When finished the section has a smooth curve to the bent section. Finally channel can also be bent in a plate roll which is typically done when bending stair stringers.


Just like wide flange and I-beam, to successfully bend channel the hard way one must use a web stretcher and/or mandrels. These tools are critical to use when bending the hard way as they keep the critical web from buckling or distorting.


We bend all mill supplied sizes which includes C3x4.1# - C15x50#.


Carbon channel (mill produced) is classified as ASTM A36 (just like angle) resulting in a yield point (psi) of 36,000 minimum.


We bend all stock lengths as well as non-stock lengths. Stock lengths come in 20 feet and then every 5 foot increment up to approximately 60 feet long. The most common lengths include 20 feet and 40 feet long.


One of the most common usages of bent channel is for stair cases. The bent channels act as the stair stringers (link to specialty bending: spiral, circular & helical bending) (supports) and are bent helically. Bent channels are also used in light structural applications like awnings and car ports typically found in residential buildings or light commercial structures.

I have worked with Albina over the years and have always appreciated the level of experience and professionalism each member of the staff has. The work produced by Albina Co., Inc. is always top notch. Brian and his staff provide excellent customer service, very fair pricing for the work being done, and they deliver when promised.

I was talking to a potential customer yesterday about fabrication of some complicated work, most of which included rolling. When asked about maintaining tolerances, I could say without hesitation that Albina would provide a product that exceeded expectations. It's good to know you have a partner that can carry their weight when bidding tough projects.
