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 H" B# A) {, X/ y' U2 B!

M) b8 k, I" P5 hthe 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.

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.4 d7 F2 Z, z/ x7 @; U1 b
& m5 ^+ Z# D6 O1 ]0 g; G7 ]# h9 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!* k% G9 ?# {7 u4 \

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.
