Cantruss, 俺来说两句。。。。哎哟，谁在扔砖头？！
"Cantruss", as well called as "Uni-strud", or "C channel", is a very commonly used industrial/commercial standard framing/supporting material, usually used to make a sort of brackets as a support to Cable Tray by using spring nuts and bolts, or use "P Clamp" to hold pipes/conduits/cables, even sometime are used to bolt onto another material directly.

F: N- Wthe most commonly used size of cantruss also called standard cantruss has its dimension of 2 5/8" by 1 7/16", with holes bored on either side or just a whole piece. other than that, we also use "shallow cantruss", which is half the depth of standard size or "double cantruss", which is pre-manufactured two standard cantruss simply back to back welded together.

Hacksaw does work as well, by you might need a little bit musle!9 D0 i" B; Q% H; f. s

Most common ways to put cantruss together is by welding, drill hole and bolt it together, or using some pre-fabricated "T" or "L" shape joiners7 W6 w6 d, `. n3 {1 f& P/ G

Steel cantruss is usually galvanized for corrosion resistance, but the galvanize also causes some problem and generate poison gas when welding . So, remember to grind the galvanize off about half inch back at either end of the welding points before you deliver it to a welder will be highly appreciated by welders.. N- D* a! F1 J( e
