Product Information

H-shaped steel is a kind of economically efficient profile with more optimized section area distribution and more reasonable strength-to-weight ratio, which is named because its section is the same as the English letter "H". Because all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used.

H-shaped steel is a new type of economic construction steel. The section shape of H-beam is economical and reasonable, and the mechanical properties are good. When rolling, every point on the section extends more evenly and the internal stress is small. Compared with ordinary I-beam, H-beam has the advantages of large section modulus, light weight and metal saving, which can reduce the building structure by 30-40%. And because its legs are parallel inside and outside, the leg end is right Angle, assembly and combination into components, can save welding, riveting workload up to 25%. It is often used in large buildings requiring large bearing capacity and good cross-section stability (such as factories, high-rise buildings, etc.), as well as Bridges, ships, lifting and transportation machinery, equipment foundations, supports, foundation piles, etc.

H-shaped steel is an efficient and economical cutting profile (there are other cold-formed thin-wall steel, pressed steel, etc.), because of the reasonable cross-section shape, they can make the steel more efficient and improve the bearing capacity. Unlike the ordinary I-shaped steel, the flange of the H-shaped steel is widened, and the inner and outer surfaces are usually parallel, which can be easily connected with high-strength bolts and other members. Its size composition series is reasonable, the model is complete, easy to design and choose.

Product Details

H-beams are divided into hot-rolled H-beams and welded H-beams (H), and hot-rolled H-beams are divided into wide flange H-beams (HW), middle flange H-beams (HM) and narrow flange H-beams (HN).

HW is H-shaped steel height and flange width are basically equal; It is mainly used for steel core column in reinforced concrete frame structure column, also known as stiff steel column; It is mainly used for columns in steel structures
 

HM is H-shaped steel height and flange width ratio of roughly 1.33~~1.75 mainly in steel structure: used as steel frame column used as frame beam in the frame structure under dynamic load.
 

 

H-shaped steel has the following characteristics:

1. High structural strength.

Compared with I-steel, the section modulus is large, and the metal can be saved by 10-15% under the same bearing conditions.

 

2. Flexible and rich design style.

In the case of the same beam height, the opening of the steel structure is 50% larger than that of the concrete structure, which makes the building layout more flexible.

 

3. Light structural weight.

Compared with the concrete structure, the reduction of the structure's self-weight reduces the internal force of the structure design, which can make the building structure foundation treatment requirements low, the construction is simple and the cost is reduced.

 

4. High structural stability.

The steel structure based on hot-rolled H-shaped steel has scientific and reasonable structure, good plasticity and flexibility, and high structural stability, which is suitable for building structures with large vibration and impact loads and strong resistance to natural disasters, especially for some building structures with multiple earthquake zones. According to statistics, in the world's devastating earthquake disaster of magnitude 7 or more, the H-shaped steel mainly steel structure buildings have the least degree of damage.

 

5. Increase the effective use area of structure.

Compared with the concrete structure, the section area of the steel structure column is small, which can increase the effective use area of the building, depending on the different forms of the building, can increase the effective use area of 4-6%.

 

6. Save labor and materials.

Compared with welding H-shaped steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy and labor, low residual stress, and good appearance and surface quality.

 

7. Easy for machining.

Easy structural connection and installation, but also easy to remove and reuse.

 

8. Go green.

The use of H-shaped steel can effectively protect the environment, which is reflected in three aspects: first, compared with concrete, dry construction can be used, resulting in less noise and less dust; Second, due to the reduction of self-weight, less soil extraction for foundation construction, less damage to land resources, in addition to a large reduction in the amount of concrete, reduce the amount of rock excavation, conducive to the protection of ecological environment; Third, after the service life of the building structure expires, the amount of solid waste generated after the structure is dismantled is small, and the recycling value of scrap steel resources is high.

 

9. High degree of industrial production.

The steel structure based on hot rolled H-shaped steel has a high degree of industrial production, which is convenient for mechanical manufacturing, intensive production, high precision, easy installation, easy quality assurance, and can be built into a real house production factory, bridge production factory, industrial plant production factory, etc. The development of steel structure has created and driven the development of hundreds of new industries.

 

10. The construction speed is fast.

It covers a small area and is suitable for all-weather construction and is less affected by climatic conditions. The construction speed of the steel structure made of hot-rolled H-shaped steel is about 2-3 times that of the concrete structure, the capital turnover rate is doubled, and the financial cost is reduced, thus saving investment.

Product manufacturing process

Welded H-shaped steel is a very important component in the production and processing of steel structures, and it is also a frequently used component. In the construction of steel structure as a steel structure beam and steel structure role, its application is very wide, today we will reveal the production process of steel structure H-shaped steel.

1. Loft

When lofting, it is necessary to clearly mark the assembly mark, the mark of the screw hole, the position direction of the reinforcement plate, and the tilt mark and the center line reference line and the inspection line, and make a sample if necessary.

2. Cut the material

When the steel plate is blanking, the impurities such as rust on the cutting surface should be removed before the cutting down, the cutting parts should be kept smooth, the slag and splash should be removed after cutting, the cutting should master the use of mechanical equipment and operating procedures, and the equipment parameters should be adjusted to the best value.

3. Organize

Before the steel plate is assembled, the deformed part should be corrected and reached within the range of control deviation. The contact surface is not free of burrs and other stains, and the measuring tools used must be accurate when assembling.

4. Weld

The welding process should adopt the portal type automatic submerged arc welding machine, and the column and beam connecting plate and ribbed plate should be welded manually.

5. Punch holes

The drilling equipment should adopt rocker arm drilling bolt hole spacing should meet the relevant standards of "Steel Structure Construction and Acceptance Code", and should use a ruler or visual inspection.

6. Correct

The equipment used for correction is the flange straightener, and the operator should be familiar with the process content, and master the operating procedures of the flange straightener, and self-check should be carried out after correction.

7. End cut

After the correction of the welded steel column and beam is completed, the end milling machine is used for flat cutting.

8. Remove rust

The rust removal process of H-shaped steel is carried out by shot blasting machine, which can improve the fatigue strength and corrosion resistance of steel.

9. Spray paint

After rust removal and inspection, it is necessary to spray the first primer and then spray the intermediate paint and top paint. After completion, quality inspection should be carried out to ensure that each coating meets the process requirements.

 

Fields of application

As the main form of modern architecture, steel structure has many unique advantages. There are many types of H-shaped steel in the market, hot-rolled H-shaped steel because of different processing methods, the scope of application in the market is also significantly different, its own use characteristics are obvious, can meet the needs of many industrial and civil buildings, effectively provide H shaped steel for the construction industry, but also naturally can be used very well.
