H beam ASTM A36 A992 Hot rolled welding Universal beam Q235B Q345B Galvanized China H beam manufacturer Companies

Short Description:

Galvanized H-beam is a corrosion-resistant profile that forms a dense zinc layer on the surface of ordinary H-beam through a hot-dip galvanizing process. It offers over 50 years of corrosion resistance (salt spray test >4,800 hours), making it particularly suitable for harsh environments such as coastal areas, chemical industries, and high humidity. While retaining the H-beam’s inherent advantages of high strength, bending resistance, lightweight construction, and ease of construction, it significantly reduces maintenance costs and extends the life of structures (e.g., in port crane rails and offshore platform supports).

PRODUCT PRODUCTION PROCESS

The production process for standard H-beams typically includes the following key steps:

Raw Material Preparation: The raw material for H-beams is typically steel billets. These billets are cleaned and heated to prepare for subsequent processing and forming.

Hot Rolling: The preheated billets are fed into a hot rolling mill. In the hot rolling mill, the billets are rolled through multiple rollers, gradually forming the cross-sectional shape of the H-beam.

Cold Working (Optional): In some cases, to improve the precision and surface quality of the H-beam, hot-rolled H-beams may also undergo cold working, such as cold rolling and drawing.

Cutting and Finishing: After rolling and cold working, the H-beams are cut and finished to meet specific dimensions and lengths as required by the customer.

Surface Treatment: The H-beams are cleaned and treated with rust prevention to ensure surface quality and corrosion resistance.

Inspection and Packaging: The finished H-beams undergo quality inspection, including inspections for appearance, dimensional accuracy, and mechanical properties. Once qualified, they are packaged and shipped to the customer.
