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.

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.3 f6 L1 g+ ~7 F7 Z8 ]

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.0 c! M. m/ G. E& J1 P( ]3 W
" a1 M# a0 G, ?' r& gThe 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!) P7 s7 w6 L! U) C [- U. b) f! |) i% p

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 joiners9 |- Q. J2 {) l

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.
