Foreword
This part of BS 4 has been prepared under the direction of the Iron and Steel
Standards Policy Committee and is a revision of BS 4-1:1980 which is withdrawn.
The major reason for this revision is to delete the requirements for tolerances on
beams, columns and bearing piles which are now contained in BS EN 10034,
published simultaneously with this standard. The opportunity has also been
taken to delete derived properties from the tables in the previous edition of this
standard.

The dimensions and masses of beams, columns and bearing piles have also been
amended slightly to correct anomalies in Table 5 to Table 7 of BS 4-1:1980.
Amendment No. 1 has been added to take into account UK requirements for
parallel flange channels.
A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.
Compliance with a British Standard does not of itself confer immunity
from legal obligations.

1 Scope
This part of BS 4 specifies the dimensions and mass
of the following hot-rolled structural steel sections:
universal beams
universal columns
universal bearing piles
joists
structural tees cut from universal beams
structural tees cut from universal columns
taper flange channels
parallel flange channels
Mass, length and depth tolerances for taper flange
joists and channels are also given.

NOTE Dimensional, mass, length and straightness tolerances
for universal beams, columns and bearing piles are given in
BS EN 10034.
2 Normative reference
This part of BS 4 incorporates, by reference,
provisions from another publication. The normative
reference is cited at the appropriate point in the text
and the publication is given on the inside back cover.
Subsequent amendments to, or revisions of, this
publication apply to this part of BS 4 only when
incorporated in it by updating or revision.
3 Designation
A section shall be designated by the serial size in
millimetres (mm) and the mass per unit length in
kilograms per metre (kg/m).
This form of designation shall be used in any
enquiry and order.
Example
a beam of 920.5 mm × 420.5 mm at 388 kg/m is
designated 914 × 419 × 388 beam.
4 Tolerances on universal beams,
columns and bearing piles
Dimensional, mass, length and straightness
tolerances on universal beams, columns and bearing
piles shall be as given in BS EN 10034.
5 Mass and length tolerances for joists
and channels
5.1 Mass
Tolerances shall be applied to the actual mass per
unit length of the joist or channel.

The rolling tolerances shall be either:
a) ± 2.5 % of the actual mass per unit length; or
b) + 5 % of the actual mass per unit length where
a minimum mass per unit length is ordered.
5.2 Length
Joists or channels ordered as “specified” or as
“exact” lengths shall be supplied as follows.
a) Specified lengths. When a joist or channel is to
be cut to a specified length, it shall be cut to
within ± 25 mm of that length. When a
minimum length is specified, it shall be cut to
within mm of that minimum length.
b) Exact lengths. When a section is to be cut to an
exact length, it shall be cold sawn to
within ± 3.2 mm of that length.
6 Tolerance on depth of section for
joists and channels
The tolerance on the nominal depth of section shall
be as given in Table 1.
Table 1 — Tolerances on nominal depth of
joists and channels
7 Dimensions of hot-rolled structural
steel sections
The nominal dimensions of hot-rolled structural
steel sections shall be as given in Table 2 to Table 9.
