FOREWORD
This Indian Standard (Third Revision )was adopted by the Bureau of Indian Standards on 6 April
1989, after the d af finalized by the Structural Sections Sectional Committee had been approved by
the Structural and Metals Division Council

Under the steel economy programme, a rational, efficient and economical series of Indian Standards z
on beam sections, channel sections and angle sections was evolved in 1957 and IS 808: 1957 was
?
published covering junior, light weight, medium weight, wide flange and heavy weight beam sections;
junior, light weight and medium weight channel sections and equal and unequal leg angle sections.
>
This standard was revised in 1964
n the second revision of this standard. parts relating to medium weight beam sections-mb series,
column sections -SC series, channel sections-mc and MCP series and equal and unequal leg angles
were revised and published as Parts 1, 2, 3, 5 and 6 of IS 808, respectively Sections not covered in E
∽巴
these parts, however. continued in IS 808: 1964.
In the present revision, the Sectional Committee felt it convenient to merge all the five parts into one
standard. The sections which were retained in IS 808: 1964 subsequent to its second revision in five
parts are included in this standard with a view that these sections although not being rolled in the
country at present may in future be rolled owing to their efficiency and resultant economy in the use

of steel. However, the designers are advised to check from JPC/producers regarding availability of

such sections
Following additional modifications have been affected in this revision
a)Medium weight beam sections MB 100 having the filange width and web thickness of 70 mm and
45 mm, respectively, has been modified to 50 mm filange width and 47 mm web thickness
∽C已Two sections, namely, BFB 150 and RSJ 200 which are mainly used in railway electrification
have been included as SC 150 and WB 200, respectively
c) Additional equal leg angles6060×4,100100×7( in place of100100×65),and130130×9
have been included in the supplimentary list;
d)Amendments issued so far to the various parts of the standard and to IS 808: 1964 have been 9
incorporated: and
e) Mass, area and other sectional properties have been expressed in three significant places
