Product Description
Product Description
Product Display
H-shaped steel is a new type of economical construction steel. H-shaped steel has an economical and reasonable cross-section shape and good mechanical properties. During rolling, the extension of each point on the cross-section is relatively uniform and the internal stress is small. Compared with ordinary I-beam steel, it has the advantages of large section modulus, light weight and metal saving, which can make buildings The structure is reduced by 30-40%; and because the inner and outer sides of the legs are parallel and the leg ends are at right angles, they can be assembled into components, which can save 25% of the welding and riveting workload. It is often used in large buildings that require large interception capacity and good cross-sectional stability (such as factories, high-rise buildings, etc.), as well as bridges, ships, lifting and transportation machinery, equipment foundations, brackets, foundation piles, etc.
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.

Product CharacteristicH-shaped steel is an economical cross-section steel optimized and developed from I-shaped steel with better cross-section mechanical properties. In particular, the cross-section is the same as the English letter "H", so it is named after it. Its characteristics are as follows:| Number | characteristic |
| 1 | Wide flange and high lateral stiffness. |
| 2 | Strong bending resistance, about 5%-10% better than I-beam. |
| 3 | The two surfaces of the flange are parallel to each other, making connection, processing and installation easy. |
| 4 | Compared with welded I-beam, it has low cost, high precision and small residual stress. It does not require expensive welding materials and weld detection, saving about 30% of the cost of steel structure production. |
| 5 | Under the same cross-sectional load, the hot-rolled H steel structure is 15%-20% lighter than the traditional steel structure.
|
| 6 | Compared with concrete structures, hot-rolled H steel structures can increase the use area by 6%, while the structure's dead weight is reduced by 20% to 30%, reducing the internal forces of structural design.
|
| 7 | 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.

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.
