Take you to understand the characteristics of several common steel

H Beam

h型钢

H-shaped steel is an economical cross-section steel optimized and developed from I-shaped steel with better cross-section mechanical properties. It is named because its cross-section is the same as the English letter "H". H-shaped steel is divided into wide flange steel (HW), mid-flange H-shaped steel (HM), narrow-flange H-shaped steel (HN), thin-walled H steel (HT), and H-shaped steel (HU), which are often used for large bearing capacity. , Brackets, foundation piles, etc. in large buildings with good cross-sectional stability.

▍The advantages of H-beam

✦Wide flange and large lateral rigidity. Strong bending resistance.

✦The two surfaces of the flange are parallel to each other, which makes the connection, processing and installation easy.

✦Compared with welding I-beams, it has low cost, high precision, low residual stress, no need for expensive welding materials and weld inspection, and saves about 30% of the steel structure production cost.

✦Under the same section load. The weight of hot rolled H steel structure is 15%-20% lighter than traditional steel structure.

✦Compared with the concrete structure, the hot-rolled H steel structure can increase the use area by 6%, while the structure's own weight is reduced by 20%-30%, reducing the internal force of the structure design.

✦H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-sectional forms, which greatly meets the needs of engineering design and production.


Square tube

The square tube is a hollow square cross-section light thin-walled steel tube, also known as steel refrigerated bending section. The square tube has good comprehensive mechanical properties, good cold and hot workability and corrosion resistance, and also has good low temperature toughness.

▍Performance of square tube

✦Plasticity Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without being damaged under load.

✦Hardness Hardness is a measure of the hardness of metal materials.

✦Fatigue The plasticity and hardness discussed above are the mechanical performance indicators of metal under static load. In fact, many machine parts work under cyclic load, and under this condition, parts will experience fatigue.

✦Impact toughness The load that acts on the machine at a great speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness.

✦Strength refers to the resistance of metal materials to damage (excessive plastic deformation or fracture) under static load.


Round tube

A round tube is a steel with open ends and a hollow and concentric cross section. The size of the round tube is expressed by the external dimensions (such as the outer diameter or side length), the inner diameter and the wall thickness, and its size range is very wide, from a small diameter capillary tube to a large round steel tube with a diameter of several meters.

▍The use of round pipe

Round pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special purposes. The other main use of round steel is process pipeline, but it generally has special material and anti-corrosion requirements.


Whether it is the processing of H-shaped steel or square tube/round tube steel, to make all the indicators can meet the requirements well, it is the key to choose the right intelligent production equipment. The steel structure production line and laser cutting machine independently developed by Zhouxiang Enterprise, The CNC plasma flame cutting machine has the characteristics of advanced technology, stable performance, easy operation, ultra-high precision, energy saving and high efficiency. It is the best choice for the processing and production of H-shaped steel, square tube/round tube steel.
