STEEL UNIVERSAL BEAM SIZES AND DIMENSIONS

Universal beam sizes, dimensions and section properties calculator per BS 4-1:2005 "Structural steel sections. Specification for hot-rolled sections". BS 4-1 standard specifies the dimensions and mass of the 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; and parallel flange channels. Dimensional, mass, length and straightness tolerances for universal beams are given in BS EN 10034.
