3.3 Actual mass. The actual mass per metre run of the
1. Scope
designated serial sizes of universal beams, columns and bearing piles can be calculated from the sectional areas given in tables 5 to 7. to 7.
This British Standard specifier the dimensions, tolerances and certain properties of the following hot-rolled structural steel sections.
3.4 Derived properties. The derived properties in
Universal beams
tables 5 to 12 are conversions from the imperial values and are provided for information. Direct calculation of derived properties from the nominal dimensions may give slightly different results.
Universal columns Universal bearing piles Joists with Joists with taper flanges
3.5 Density of steel. The mass of steel is calculated on the basis that steel has a density of 7850 kg/m³.

4.1 Mass. Tolerances shall be applied to the actual mass 2. Designation
per unit length of the section.
A section is designated by the serial size (nominal (nominal size) in millimetres and the mass per unit length in kilograms per metre.
The rolling tolerances shall be either:
(a) ± 2% % 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 required.
This form of designation shall be used in any enquiry any enquiry and order.
4.2 Length. Sections ordered as ‘specified’ or as ‘exact’ lengths shall be supplied as follows.
Examples (a) (a) A beam of 920.5 mm × 420.5 mm at 388 kg/m shall be designated 914 × 419 × 388 beam.
(a) 'Specified' lengths. When a section 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 +50, -0 mm of that minimum length.
(b) (b) A rolled tee of 50.8 mm × 50.8 mm at 6.92 kg/m shall be shall be designated 51 × 51 × 6.92 rolled tee.
3. Basis of calculation
lb) 'Exact' length When a section is to be to be cut to an ‘exact’ length, it shall be cold sawn to within ± 3.2 mm of that length.
3.1 Designated dimensions. The designated dimensions given in tables 5 to 12 to 12 have been convened from the imperial values using 25.4 mm = 1 in.
3.2 Designated mass. The designated masses per metre run for universal beams, columns and bearing piles given in tables 5 to 7 have been converted from the imperial masses per metre run and rounded to whole numbers.

Foreword
In recent years international agreements have resulted in certain types of structural steel sections being produced in metric ranges instead of the former imperial ranges. Such metric sections have been standardized in BS 4848. the following Parts of Parts of which have so far been published: Part 2. Structural hollow sections Part 4. Equal and unequal angles Part 5. Bulb flats. Pending international agreement and subsequent consideration by the British Standards Institution. all other types of section are still being produced on an imperial dimensional basis although designated in equivalent metric terms.

This fifth revision of this British Standard has been prepared under the direction of the Iron and Steel Standards Committee, and is based mainly on BS 4 : Part 1 : 1972.

This new edition of BS 4 : Part 1 updates the standardization of such sections secti ons taking into account the Progress in publishing the above Parts of BS 4848, certain deletions in production ranges and minor modifications to flange shape in universal beams. In the latter respect it should be noted that all universal beams have been produced with parallel flanges since January 1978, with properties as shown in this standard Properties of universal beams with tapered flanges produced prior to January 1978 were included in BS 4 : Part 1 : 1972. The opportunity has also been taken to correct minor errors in the data published in the 1972 edition.

5. Dimensional rolling tolerances for universal beams, columns and bearing piles 5.1 Cross section. The section. The variations from the specified dimensions and the correct cross section shall not exceed those shown in figure 1 and tables 1 and 2. 5.2 Straightness. The variations from straightness shall not exceed those given in table 3. 5.3 Thickness. The Thickness. The variations from the nominal thickness of web and flanges shall nor exceed the tolerances given in table 1 (c). For sections 457 × 152.406 × 140. 305 × 102 and 254 × 102. the tolerances on flange thickness in table 1 (c) shall apply apply only when the flange width B is greater than or equal to the designated width. Where the flange width is less than the designated width, the flange thickness T shall not be reduced by more than 10 % of the nominal flange thickness.
