Where on the site would I find suitable rail material? What do I look under? I have been using uni-strut but looking at other materials. Thanx all.

The 1" x 1" extrusions use 1/4" buttons and are suitable for mid power and high power rockets to ~ 50 pounds.
The 1 1/2" x 1 1/2" extrusions mentioned by Joel use 5/16" rail buttons are best for L3 projects over 50 pounds.
