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. / \3 h0 ?. _/ h K$ J% Y

the 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.9 n$ {4 f A1 S0 h3 c0 W!

: s7 M5 Q7 e. {. H: |# SThe 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!& e! [2 P$ l8 r+ j/ P8 G

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 joiners! h8 l0 R% l$ C

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.
