GEOMETRY TOLERANCES #

Angle defect at cut end: Cutting angel is max. 5 mm.

Flatness at cut end: Deviation from flatness is max. 2 mm.

Angel defect of cross-section: N/A

Deflection on the whole bar (laterally and vertically): Total straightness deviation doesn’t exceed 3 mm.

Local deflection (laterally and vertically): Straightness (on flat and edge) is no more 3 mm per meter length.

Side face straightness: max. 2,5 mm – for 122×122, 140×165, 140×100 mm

max. 3,5 mm – for 122×115, 122×130, 140×147 mm.

Twist on the whole bar: Not exceed 3 mm/m, max. 3mm on the total bar length.

Radius of corners (R): R = 9, 13, 15, 18, 21 mm, it is allowed to round off the corner by abrasive cleaning.

SURFACE CONDITION #

Lateral surfaces: Rough breaks with visual non-metallic inclusions in overall dimensions more than 50 mm in any directions are not allowed on the surface.

Surface roughness: Cut by saw in cold condition, it is not allowed  burrs are more than 4 mm.

Cut by saw: Angle defect is max. 5 mm.

Scale: Scale is not removed.

Painting/Coating: No painting/ no coating of surface and ends.
