Description

H Beam Steel is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter “H”. Since all parts of H-shaped steel are arranged at right angles, H Beam Steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.

We are a Chinese steel manufacturer with a wide range of products and sufficient stock.We can produce and supply various specifications of section steel, H-section steel, I-beam, angle steel, channel steel, etc. Welcome friends from all over the world to consult and buy.

Classification of H Beam Steel:

H Beam Steel includes carbon steel H-shaped steel, galvanized H-shaped steel, stainless steel H-shaped steel, etc.

According to the production method, it is divided into welded H-shaped steel and rolled H Beam Steel.

Product execution standards: GB, BSEN, ASTMA6/A6M-12, DIN EN, JIS, ISO, KS.

British standard H steel: UB, UC

European standard H-shaped steel: HEA, HEB, HEM, such as IPE240 EN Standard I Beam Steel.

American standard H steel beam: W4*13-W40*3923, such as ASTM A992 Wide Flange H Beam Steel.

Material grades include:
S235, S275, S355 level JR/J0/J2/NL/ML/K2
ASTM A36, A572 Gr.50, A992
JIS SS400, SM490A, SM490B, SM490YA, SN490B
Q345D, Q345E, Q420D, Q460D, Q460E, Q550D, Q690D, Q690E, Q960D, Q960E

H-beam steel, due to its high strength-to-weight ratio, excellent load-bearing capacity, and ease of construction, is widely used in structural load-bearing and frame systems for buildings, bridges, machinery, transportation, and marine engineering.

1. Building Structures: H-beam steel is used for beam-column frames in industrial plants, high-rise and super high-rise buildings, and residential buildings, especially suitable for large spans, heavy loads, or seismic fortification areas.

2. Bridge Engineering: Main beams, pier supports, and bridge deck components for highway and railway bridges; large-size H-beam steel can replace traditional concrete structures.

3. Machinery and Equipment: Heavy-duty machine tool bases, crane booms, frames for construction machinery (such as excavators and loaders), and support frames for automated production lines.

4. Transportation and Energy: Railway catenary supports, highway guardrail posts, power transmission towers, and wind turbine tower foundations.

5. Marine and Shipbuilding: Ship frames, offshore platform structures, and port and dock piers.

6. Underground and Special Engineering: Foundation pit support piles, mine supports, dam reinforcement, and foundation treatment (such as H-beam piles).

7. Others: Petrochemical storage tank frames, power equipment supports, railway vehicle beams, and temporary prefab structures, etc. H Beam Steel is classified into wide flange (commonly used for columns) and medium/narrow flange (commonly used for beams) according to flange width. It can be rolled or welded to meet diverse needs from civil construction to heavy industry.
