The steel beams (sections) classification mostly used in Europe I-beams (I-shaped cross-section). IPE - European steel i-beams have parallel flange surfaces and height 80-600(mm): according to Euro norm 19-57; Tolerances: EN10034:1993. Also, manufacturers supply additional range of IPE from 80 mm to 750 mm height. IPN - European standard beams (I-shaped cross-section) have a slope 14% on the inner flange surfaces and range of height 80-600(mm). Dimensions: DIN 1025-1:1995, NF A 45-209 (1983). Tolerances: EN10024:1995 HE - European wide flange beams have parallel flange surfaces and approximate equal width and depth 100-1000(mm). HL - European extra wide flange beams have parallel flange surfaces and depth 920-1100(mm). HD - European wide flange columns have parallel flange surfaces and depth 260-400(mm). HP - European wide flange bearing piles have parallel flange surfaces and depth 200-400(mm).   U-Profiles (channels) UPE- European channel with parallel flanges have depth 80-400(mm). UPN- European channels with taper flange have depth 80-400(mm). U - European channels with taper flange have depth 40-65(mm). Angles (L-shaped cross-section) L- shapes are equal leg and unequal leg angles

The steel beams (sections) classification used in UK.                       I-beams (I-shaped cross-section) UB - Universal Beams (I-shaped beams) have parallel flange surfaces. J - Joists (I-shaped beams) have a slope on the inner flange surfaces. UC - Universal Columns are ‘H’ shaped sections have equal or near-equal width and depth. UBP- Universal Bearing Piles are ‘H’ shaped sections have parallel flange surfaces and equal (or near-equal) web and flange thicknesses, stocky webs and flanges.   C-Profiles (channels) CH - Taper flange channels. PFC- Parallel flange channels. Angles (L-shaped cross-section). They are often used to carry tension loads and can be bolted or welded to other members. UE - Angles are unequal angles have legs of different lengths. E - Angles are equal angles have both legs of the same length.   A Hollow Structural Section (HSS) is a type of metal profile with a hollow tubular cross section. In some countries they are referred to instead as a structural hollow section (SHS). RHS - Hot finished rectangular hollow section. CHS - Hot finished circular hollow section. SHS - Hot finished square hollow section.

The steel sections classification mostly used in North America Values are presented in either Imperial (inch-pound) units or SI (metric) units. The data presented in each system isn't exactly equal; therefore, each system should be used essentially separately. Combinations values from these systems aren't allowed. (ASTM A6/A6M). I-beams (I-shaped cross-section) W - Wide flange steel beam (I-shaped cross-section) have parallel flange surfaces. S - American Standard Beam (I-shaped cross-section) have a slope on the inner flange surfaces. HP - Bearing Pile (H-shaped cross-section) have parallel flange surfaces and equal web and flange thicknesses. M - Miscellaneous shapes cannot be classified as standard i-beams (W,S,HP), available from a limited number of manufacturers.   Channels (C-shaped cross-section) C - American Standard Channels have a slope on the inner flange surfaces. MC -American Miscellaneous Channels cannot be classified as standard channels, available from a limited number of manufacturers.   Angles (L-shaped cross-section) L - shapes are equal leg and unequal leg angles.
