European foreword
This document (EN 10210-2:2019) has been prepared by Technical Committee CEN/TC 459 “ECISS -
European Committee for Iron and Steel Standardization” , the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2019, and conflicting national standards
shall be withdrawn at the latest by November 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 10210-2:2006.
The main changes with respect to the previous edtion are listed below:
a) paragraph 5.2 two options were added;
b) in Table 2 the mass tolerances were changed;
c) Figure 2 was updated;
d) for Tables B.1, B.2 and B.3 larger sizes and wall thicknesses were added;
e) standard was editorially revised.
This standard consists of the following parts:
— EN 10368, Steel structural hollow sections — General (Characteristics, evaluation of conformity and
marking) (in preparation)
— EN 10210-1, Hot finished steel structural hollow sections — Part 1: Technical delivery conditions
— EN 10210-2, Hot finished steel structural hollow sections — Part 2: Tolerances, dimensions and
sectional properties
— EN 10210-3, Hot finished steel structural hollow sections — Part 3: Technical delivery conditions for
mechanical engineering purposes (in preparation)
It forms part of a series of standards on hollow sections together with EN 10219-1 to EN 10219-3.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.

Through its subcommittee SC 3 “Structural steels other than reinforcements” (secretariat: DIN)
1 Scope
This document specifies tolerances for hot finished circular, square, rectangular and elliptical structural
hollow sections, manufactured in wall thicknesses up to 120 mm, in the following size ranges:
— Circular: Outside diameters up to 2 500 mm;
— Square: Outside dimensions up to 800 mm × 800 mm;
— Rectangular: Outside dimensions up to 750 mm × 500 mm;
— Elliptical: Outside dimensions up to 500 mm × 250 mm.
The formulae for calculating sectional properties of sections manufactured to the dimensional
tolerances of this standard, to be used for the purposes of structural design, are given in Annex A.
Dimensions and sectional properties for a limited range covering the more common sizes are given in
Annex B.
NOTE The designation of the sections' major axis (yy) and minor axis (zz) aligns with the axis designation
used for structural design in the structural Eurocodes.

5 Information to be obtained by the manufacturer
5.1 Mandatory information
The following mandatory information from this part of EN 10210 shall be obtained by the manufacturer
at the time of enquiry and order:
a) the dimensions (see Clause 8);
b) the type of length, length range or length (see Table 3).
NOTE This Information is included in the list of information to be obtained by the manufacturer contained in
EN 10210-1.
5.2 Options
Options are specified in this part of EN 10210. In the event that the purchaser does not indicate a wish
to implement one of these options at the time of enquiry and order, the manufacturer shall supply in
accordance with the basic specification.
+150
Option 2.1
The tolerance on approximate length shall be mm (see Table 3).
Option 2.2 Tolerance of external corner radius of 2T maximum at each corner.
Option 2.3 Out-of-roundness tolerances for diameter to thickness ratio exceeding 100 (see
Table 2, footnote d).
6 Tolerances
6.1 Tolerances shall not exceed the values given in Table 2 for shape, straightness and mass, Table 3
for manufacturer's delivered length and Table 4 for the height of the internal and external weld bead of
submerged arc welded hollow sections.
6.2 The internal corners of square and rectangular hollow sections shall be rounded, except in the
case of EW sections for a corner containing the weld, should the weld be located in the corner region.
NOTE The internal corner profile is not specified.

For elliptical hollow sections of sizes H < 250 mm, the permitted tolerance is twice the value given in this
table.

The positive deviation is limited by the tolerance on mass.
c
For seamless sections thicknesses of less than 10 % but not less than 12,5 % of the nominal thickness may
occur in smooth transition areas over not more than 25 % of the circumference.
d
When the diameter to thickness ratio exceeds 100, application of tolerance on out-of-roundness is not
required, unless specifically agreed (see 5.2).
e
The tolerance on convexity and concavity is independent of the tolerance on outside dimensions.
f
The sides need not be tangential to the corner arcs.
