Length tolerace:
The length tolerace for sheet length up to 2500 mm is max. +5/-0 mm.
The length tolerance of sheet cuts can vary with a total tolerance range not exceeding the above given value. The maximum sheet dimensions depend on the sheet thickness.other dimensions upon request.
Sheet with premium surface condition are available from 0.15 to 1 mm.Sheet with thickness from 0.127 to 0.381 mm can be delivered as coils upon request.(production length max.10500mm)
Flatness:
Max.1% for sheet thickness≥0.3mm
Max.4% for sheet thickness<0.3mm
(measuring proedure on the basis of ASTM B386)

Surface condition
Appearance: The material will be of uniform quality, free from foreign matter, splits and fractures. bed sheet(not trimmed) may have small edge cracks.
Surface defects are assessed in the frame of visual inspection.
Local surface defects can be removed by frinding within the specified thickness tolerace.
Surface condition: Cold rolled, bright(≤1mm) Ra≤0.20μm
Cold rolled, pickled: Ra≤1.00μm
Cold rolled ground: Ra≤0.60μm
