Tailor made solutions

Siderval works in close collaboration with its customers to define tailor-made profile solutions. In some cases, this approach reduces the need for machining and increases material yield, while in others it obviates the need to assemble standard products to obtain complex shapes, resulting in a product without joints or welds.

Do you need a special profile? Not standard, but with a specific section?
We can provide technical and commercial support for the realization of your solution.

Just send us a sketch or a technical drawing.

INDICATIVE PROFILE TOLERANCES

HOT EXTRUDED AND STRAIGHTENED – HOLLOW SECTION

Up to 50 mm: ± 0,5 mm
> 50 mm: ± 1%
Thickness S: ± 10% of nominal thickness

Up to 50 mm: ± 0,5 mm
> 50 mm: ± 1% (or less if possible)
Thickness S: ± 15%
Thickness of the fin e: ± 0,5 mm
Width of the fin  b: ± 2 mm (or less if possible)

Tolerances on other hollow profiles need to be defined based on the specific shape. For all other tolerances see full section profiles table.

HOT EXTRUDED AND STRAIGHTENED – FULL SECTION

<25 mm: ± 0,5 mm
From 25 to 75 mm: ± 0,8 mm
From 75 to 100 mm: ± 1,0 mm
From 100 to 125 mm: ± 1,2 mm
>125 mm: ± 1,4 mm

Ri = Internal radius: minimum 4+2 mm
Re = External radius: minimum 1,5 ± 0,5 mm

Type  1 ± 1°30’
Type 2  ± 0°30’

X max.= 1% of M
(Less if allowed by the specific shape)

X max. = 0,15% of L

Maximum deviation 1mm every 1000 mm or less if allowed by the specific shape.

Max. difference between S and S’
half the tolerance of A

e.g.: S = S’ = 28 ± 0,8mm
max. difference 0,8 mm
(S = 27,6 S’ = 28,4)

Max. variation: half the overall
tolerance of A

E.g.: nominal measure
M = M’ = 80 ± 1 mm
A = A’ = 40 ± 0,8 mm
S = S’ = 15 ± 0,5 mm

E.g.:
M = 79,5 M’ = 80,5
A = 39,4 A’ = 40,2
S = 14,75 S’ = 15,75

a) Standard production: ± 1000 mm
b) fixed length: ± 2 mm; up to 10 m  (tighter upon request)
c) multiple: + 5 mm each multiple (tighter upon request)
d) Commercial length: 3000mm-7000mm
