You can not cut the steel sheet Bulgarian: tell why

FROMotni just saw in the construction workers cut steel sheet ordinary grinder with a disc of metal, but a recent conversation with a competent builder I was literally stunned. He convinced me that the use grinders for cutting trapezoidal sheet impossible. I will share its expertise with you.

At first, When sawing steel sheet grinder, it damages the anticorrosion metal layer, and the resulting sheet rust much faster than expected.

SecondlyOn many profiled sheets applied polymer layer today and sparks from the grinder it can burn. Result - lost appearance.

FROM cons like everything is clear, but it is not clear what to cut steel sheet instead of grinders?

Hailuchshim tool cutting trapezoidal sheet, according to my informant, is a hacksaw - because it can make perfectly smooth the segment, without a "burr". By cons hacksaw include the fact that it is not suitable for curvilinear cutting the profiled sheet.

FROM this task can handle fretsaw - manual or electric. Jigsaw sawing sheet slower, but more gently, and

It does not break the protective layer of profiled sheet, So your roof or fence will last several times longer!
