New metal carport

I'm building a R-panel carport. 24x24x8 w/6 square tube posts and 8" cee purlins. The guy that will put it up for me is recommending 8" receiver channel instead of 8"cee purlin on 2 sides. North Central Texas doesn't get snow but we often get 60mph wind gusts so stability is required. It would go up faster and look cleaner but I've always thought cee purlin is stronger than receiver channel. Any real world experience using receiver on sides rather than purlin?

Did a google search to understand the term Receiver Channel. Several answers. This site, being a steel co. making numerous shapes with nothing to gain
or loose has this comment: https://eaglesteel.com/product/receiver-channel/

Then I just asked google about Cee channels and came up with several more comparisons with that and Zee panel. Might check out the experts. I have
always used Cee but I'm not a contractor.

Another thought, not knowing how the different panels are installed and thus the benefit of the different shapes for strength, if you look at the deflection equation of a center force sitting on a beam supported on both ends, (relating a side panel supported by the vertical roof supports and the potential deflection at the center of the space between the posts due to wind load) the "height" of the "beam", thinking about a vertically mounted 2x4 vs 2x8 or whatever, that element is of the 3rd power whereas other parameters are first or second.

So a 2x4 vertically mounted (4" height) widget would have a height factor of 64. Doubling the height to a 2x8" gives a factor of 512 and tripling the height to 2x12" gives 1728. So if a 64# weight caused an initial deflection of 1" on the 4" beam, it would take a 512# weight to get 1" deflection on the 8" and a 1728# weight to get 1" on the 12". So, wind load resistance could be drastically improved by the shape of the beam.

Therefore, if the Zee or Receiver panels, due only to their cross sectional "width" difference for the same size, when installed amounted to a thicker dimension, your wind resistance would follow the above numbers and get stronger really fast.
