Channel Dim's

[kthree]

Three of the structural products we use in the manufacture of our product are small channels, 3 x 4.1#, 2 x 2.32#, and 1-1/2 x 1.12#. All the reference books we have do not contain enough data to properly draw these items when we are drafting fabrication drawings. Altogether it is no big deal because we simply measured the items and made our own reference drawings. It is a curiosity though. From all my searching I have not found a source providing the Usual Gage, Grip, and Fillet Radius for these items. Any ideas or suggestions any may wish to offer about this will be greatly appreciated. Thanks, K.

i've never seen "#" symbol used for a dim ... wonder if ".32#" means 32 wire gauge (0.01" thk) ?

The # dimension is lbs./ft of the section. Since the rolled sections have taper, it's tough to give a thickness dimension, so the convention is the weight per foot instead. Also, the depth of the channel is per the standard or convention. I've got a nice little red book from Ryerson steel that gives all the pertinent dimensions for channels and other shapes. I think Machinery's Handbook also has the data.

Ryerson's stock list is here:

btrueblood is correct that the # is weight in pounds per linear foot.

Dimensions for AISC standard channels can be found in the AISC Steel Construction Manual (14th Edition is current). An online spreadsheet of sizes is also available. Be aware that the C2 and C1 1/2 sizes are smaller than the AISC standard.

Those are ‘bar sized’ channels and may very a little from mill to mill. The height and flange width should be pretty much the same though. Usually, when designing and detailing around those bar sized sections you try to avoid needing to be very specific about the other dimensions. When all else fails you do need to measure your existing stock, or ask your supplier for the dimensions on the stock he is going to deliver.

Hi

Here is another link with lots of info:-

The only data I have is for the 3 x 4.1# since as fegenbush stated, the '2' and '1 1/2' are not part of the standard.

Thanks All. These sizes being below the AISC list is the answer I was expecting, but was hoping for different. And Yes dhengr, like you offer we have noticed a bit of differences from mill to mill. Even tho the differences are slight, we keep our jig locations on the edges and back. Appreciate everyone's considering and responding to my post. K.
