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prepared under the direction of the Iron and Steel Standards Policy Committee and is a revision of BS 4-1:1980 which is withdrawn.The major reason for this revision is to delete the requirements for tolerances on beams, columns and bearing piles which are now contained in BS EN 10034,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 beamsuniversal columnsuniversal bearing pilesjoists

structural tees cut from universal beamsstructural tees cut from universal columnstaper flange channels

parallel flange channelsMass, 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; orb) + 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

Nominal depth Maximum permissible

variation from specified

depth Over Up to and
