What is H-Beam?
H-beams are shaped like an H. H-beam is a structural beam made of rolled steel. It is incredibly strong. It gets its name because
it looks like a capital H over its cross section.
What is I-Beam?
An l -beam is shaped like an I. The I beam consists of two horizontal planes, known as flanges, connected by one vertical component, or the web. I-beam has tapered edges and it gets its name from the fact that it looks like a capital I when you see it from its cross section. With an I-beam, the height of the cross section is higher than the width of its flange.

Due to the above advantages, H-beams are widely used, mainly used for: various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activity and high temperature working conditions; requirements Large-scale bridges with large bearing capacity, good section stability and large spans; heavy equipment; highways; ship skeletons; mine support; foundation treatment and embankment engineering; various machine components.

internationally, the product standards of h-beams are divided into two major categories: the imperial system and the metric system. the united states, britain and other countries adopt the imperial system, while china, japan, germany and russia adopt the metric system. although the units of measurement used in the imperial system and the metric system are different, most h-beams use four sizes to indicate their specifications, namely: web height h. flange width b, web thickness d and flange thickness t. although countries around the world have different ways of expressing h-beam size specifications. however, the product size specification range and dimensional tolerances of the products produced are not much different.
