Steel beams are long strips of steel with an I-shaped cross-section. They come in standard and lightweight versions and are widely used in steel structures such as buildings, bridges, and factories. They offer high strength, corrosion resistance, and ease of fabrication.

TYPES AND APPLICATIONS

Standard I-beams: Primarily used in load-bearing structures, such as factory beams and crane beams.

Lightweight I-beams: Suitable for applications requiring high weight, such as lightweight factories and storage platforms.

APPLICATIONS

Bridge Construction: For example, the Yanji Yangtze River Bridge utilizes a four-cable suspension bridge design. The main span steel beam weighs 830 tons per section, requiring innovative construction techniques to address the load balancing challenges caused by the difference in sag between the inner and outer main cables.

Factory Construction: Commonly used in the construction of steel structures such as factories and warehouses, such as I-beam lofts and second-story platforms.

CONSTRUCTION AND SAFETY

Lifting Requirements: Steel beam lifting must strictly adhere to safety regulations. If using a cable-mounted crane, real-time monitoring of force changes is required to ensure balance between the internal and external cables.

Safety Protection: During construction, a hanging, hanging, or sliding safety net must be installed to prevent falls from heights.
