Instruction of H Beam
H-beams are a very strong structural steel element. They are called H-beams because their cross-section resembles the capital letter “H”.
The two parallel flanges of H-beams are of equal thickness and do not have any taper on the inner surface. Depending on the height and flange width; H-beams are divided into three categories. They are:
1.Wide flange series H-beams
2.Medium flange series H-beams and
3.Narrow flange series H-beams.

Applications of H Beam
H beams are ideal for use in mezzanines, decks, bridges and other general residential and commercial construction due to their thick walls and flanges.
Wide flanges are commonly used in residential projects. the internal dimensions of the H-beam are constant in order to make it the material of choice for trailer and truck structures.
In addition to commercial and residential construction projects, they are used in the manufacture of tracks, lifts, trailer and truck bases, winch and lift structures and support columns.
Advantages And Disadvantage of H Beam
- Due to its slightly different section shape, the central web is thicker and the flange is wider. H-beam can bear greater load than I-beam. Although both are advantageous load-bearing structures, they are more reliable in large projects because of the large span of H-beams.
- Steel beams are strong and widely used, but they do have some disadvantages compared with wood beams. Steel beams make skyscrapers possible. The cost of steel beam is very high and heavy. It will rust and pollute the environment over time.
Packing and Shipping of H Beam
The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.
The Difference Between H-beams and I-beams
H beams and I beams: dimensions and weight
- The webs of H-beams are much thicker than those of I-beams.
- I-beams usually have a flange slope of 1:6 to 1:10, whereas I-beams have a uniform flange slope.
- H-beams are heavier than I-beams.
- The flange distances can be widened according to the requirements of the H-beam section, but the flange distances of I-beams are fixed.
- The two beams have different moments of inertia.
- In I-beams the web dimensions are greater than the flange dimensions, whereas in H-beams the web dimensions may not be greater than the flange dimensions.
H-beams and I-beams: mechanical properties
- Compared to H-beams, I-beams are less resistant to torsion in cross-section.
- In general, H-beams are more rigid and can carry more loads than I-beams.
- H-beams are used as columns, whereas I-beams are used as beams.
H-beams and I-beams: Manufacturing
- I-beams are always manufactured as a single unit, but H-beams are usually manufactured by welding 3 pieces of metal together.
- H-beams can be manufactured to any desired size and height, whereas I-beams are limited by the capacity of milling machines

The nominal flange width and depth of the beam or column specified in the standard are the same, but the nominal depth of the beam is 300mm. When the depth of the beam is greater than 300mm, the nominal flange width is 300 to 400mm. The sections of beams and columns are made of heavy, medium and light flange and web thickness.
To calculate the necessary depth of a beam, divide the span in inches by 20. for example, a span of 25 would be 25 x 12/20 = 15. the width of this beam should be between 1/3 and 1/2 of the depth. The main beam is the same size but with thicker flanges.
