Building strapping

Im not sure what it's called, CTC can you enlighten me? But it's cheap and easy to work with. I've used it on Retro bot for the extra battery holder http://letsmakerobots.com/node/8004 You should be able to get it from you local building supplies store. Easy to bend, and cut it with tin snips.

Yeah but what is it called? :P
I've used this stuff a few times before, and it's probably the strongest material for building small to medium bots that you don't need machine tools for. The little diamonds make bending and cutting easy as Ant has said, and you can easily bolt the pieces together since there are regularly spaced holes. The only downside I've found is weight; it can be quite easy to go overboard if you don't use this stuff sparingly. Galvanised steel won't rust in a hurry, but it still weighs pretty much the same as normal steel.
