I beam
Description: I beam, also called girder, is one kind of profiled bars which is strip profiled steel with the "I" shape sections. The specification is usually expressed by middle height (h) *bottom width (b) * middle width (d), for instance, "I 160*88*6", shows that I beam with 160mm bottom height, 88mm middle width, 6mm middle width. Use: can be widely used in various construction structures, bridges, autos, brackets, mechanisms and so on. Specification necessary for inquiries: product name, standard performed, materials, specification (geometry dimension), quantity, weight of bundle, handling time, length, measure ways.
