Steel Profiles and Shapes - Standard to Complex Steel Profiles and Steel Shapes

THE BEST SOLUTIONS -
FOR THE MOST COMPLEX STEEL PROFILES AND SHAPES

Siderval delivers steel profiles at competitive prices, low quantities, with the quality that you deserve.
Hot extrusion in the manufacture of steel profiles offers considerable advantages over machining and welding.
Tooling costs are low and make it possible for small quantities of your custom profiles.

In addition to custom and special steel profiles and shapes,
Siderval can also produce standard structurals such as:

T-Profiles, L-Profiles, Z-Profiles, U-Profiles, H-Profiles,
Seamless Fin Tubes, Hexagonal Profiles, Omega Tubes and Double Omega Tubes.

All standard qualities of steel are available
including stainless steel, alloy steel and carbon steel.
Special hot extruded solid and hollow profiles are avaiable in cross sectional area
from 300 to 10,000 mm².

STANDARD STEEL PROFILE TOLERANCES

STANDARD PROFILE TOLERANCES
HOT EXTRUDED AND STRAIGHTENED - HOLLOW STEEL PROFILES

PRINTABLE
VERSION

Up to 50 mm:	± 0.5 mm
Over 50 mm:	± 1%
Thickness 5:	± 10% of the nominal thickness

Up to 50 mm:	± 0.5 mm
Over 50 mm:	± 1%
Thickness 5:	± 15%
Thickness of fine e:	± 0.5 mm
Width of fin b:	± 2 mm (or less on agreement)

The tolerances of other hollow profile shames must be agreed after study. For all other tolerances see table for solid section profiles.

HOT EXTRUDED AND STRAIGHTENED - SOLID STEEL PROFILES

DIMENSIONAL TOLERANCES
OF THE TRANSVERSE SECTION:

Less than 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	± 12 mm
over 125 mm	±1.4mm

WARP:

Max deviation of 1 mm per meter or less (on agreement) according to requirements.

MINIMUM RADII:

Ri = Internal radius:
minimum

mm
Re - external radius:
minimum 1.5 ± 0.5 mm

DIMENSIONAL DIFFERENCES
BETWEEN SYMMETRICAL PARTS

Max difference between S and S" half tolerance of point A

e.g.: S = S" = 80 ± 0.8 mm
max difference 0.8 mm
9hypothesis S = 27.6 S" = 28.4)

ANGULAR TOLERANCES:
steel profile angular tolerances

Type 1 case ± 1°30' Type 2 case ± 0°30'

DIMENSIONAL DIFFERENCES
BETWEEN SYMMETRICALL PARTS:

Max variation:
half tolerance as point A

e.g.: nominal values
M = M' = 80 ± 1 mm
A = A' = 40 ± 0.8 mm
S = S' = 15 ± 0.5 mm

Example:
M = 79.5 M' = 80.5
A = 39.4 A' = 40.2
S = 14.75 S' = 15.75

TRANSVERSE CURVATURE::
steel profile angular tolerances

X MAX = 1% OF M
(OR LESS ON AGREEMENT)

LONGITUDINAL CURVATURE:
steel profile angular tolerances

X max. = 0.15% of L

LONGITUDINAL BAR TOLERANCES:

a) from production ± 1 meter
b) fixes: ± 2 mm; from 0±10mm (or on request)
c) multiple: + 5 mm each multiple (or on request)
d) commercial: from 3 meters to 7 meters

Profiles are available in Carbon Steel Grades, Alloy Steel Grades,
Stainless Steel Grades, Nickel Alloy Grades and Titanium Grades.

We can present you with the best quality steel profies and shapes
coupled with superior customer service.
