Hot-rolled and welded H-beam
H-beam is an important structural material widely used in construction and engineering. According to different production processes, H-beam can be divided into hot-rolled H-beam and welded H-beam.
1. Hot-rolled H-beam
Features
Hot-rolled H-beam is formed by heating raw materials and rolling, and has high strength and toughness.
2. Welded H-beam
Features
Welded H-beam is assembled by welding after cutting steel plates, and has high flexibility and customization.
Features | Hot-rolled H-beam | Welded H-beam |
Production process | Hot-rolled | Steel plate welding assembly |
Strength | High strength, high toughness | Adjustable strength, depending on |
Dimensional accuracy | High precision, standardized production | Can be customized according to needs |
Applicable scenarios | High-rise buildings, bridges, | Lightweight construction, special design |
Cost | Strong economic efficiency, suitable | Higher cost, suitable for small batches |
Construction speed | Requires on-site processing, slow | Can be made in advance, faster construction |
Hot-rolled H-beam and welded H-beam have their own advantages and disadvantages. Hot-rolled H-beam is suitable for structures with heavy loads, while welded H-beam is more flexible and suitable for customized design. Choosing the appropriate type of H-beam according to specific project needs and budget can ensure the safety and economy of the project.
