How many tons can the No. 30 I-beam load?
I-beam is also called steel girder (English name Universal Beam). It is a strip of steel with an I-shaped section. I-beam is divided into ordinary I-beam and light I-beam, H steel three. It is a section steel whose shape is trough.
Tension and compression are not the same, and with slenderness ratio is related, material is also related, Q235B tensile strength design value is 190~215N/mm2
I-beam is mainly divided into ordinary I-beam, light I-beam and H steel three. Ordinary I-beam, light I-beam flange is variable cross-section, depending on the thickness of the web, the external thin; H steel: HW, HM, HN, HEA, HEB, HEM and so on, the flange of I-beam is a uniform section.
30# I-beam is divided into 32A and 32C two, bearing respectively 9.7T and 10.6T, that is, each two supporting iron pipe can load 9.7 tons.
