I will post my question here as it relates to "aluminium warehouse"

how accurate they doing cuts ?
let's say that I need 200x200mm aluminum plate., they declared that "Cutting Tolerance: + 2.0mm / - Nil", it will be very complicated to get rid of extra 1 or 2mm on table saw or chop saw I thing?.
Maybe it will be better to make orders on over sized plates?, and after cut to size what I need?

Thanks
