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.

Most cantruss are made by steel, however, we do see aluminum cantruss some time as well, for an instance, the rung or a ladder tray.( ?' r7 U3 B, g& Q8 a

The best way to cut a contruss is by using chop saw, however chop saws are banded on some jobsite in Alberta, which is very wired. other means of cutting a contruss might be band saw, sawsall(reciprocating saw), or hydraulic cantruss cutter. Hacksaw does work as well, by you might need a little bit musle!, y! w2 E6 K( B/ o- Z# r) W
