Q235B carbon steel channel steel is commonly used in the construction of various building facilities such as garages, warehouses, workshops, sports venues, parking lots, and other metal building walls. Its usage is similar to that of traditional wooden structures such as support beams. Channel steel is a long strip of steel with a groove shaped cross-section, belonging to carbon structural steel for construction and machinery. It is a complex section steel with a groove shaped cross-section. Specifically, hot-rolled channel steel is commonly used in arched building structures and can be welded to support or suspend various facilities. They are often used in conjunction with beams. The hot-rolled channel steel supplied by Wanzhi Steel has good welding performance, riveting performance, and mechanical properties.

The production process of channel steel mainly includes steps such as steelmaking, rolling, and cooling. Smelting iron ore and other raw materials into a blast furnace to obtain molten steel. Then, the molten steel is cast into steel billets and processed into channel steel through hot rolling or cold rolling processes. After cooling and surface treatment, the channel steel can be put into use.

Q: The first letter of the pinyin of the character “qu” for yield strength.

235: indicates that its yield strength is ≥ 235 MPa. This is the fundamental indicator of its carrying capacity.

B: Indicates a quality level of B, ensuring impact toughness at room temperature (+20 ° C). This means that it has good fracture resistance at room temperature and is more suitable for structures with certain dynamic loads or environmental temperature changes than Class A (which does not guarantee impact toughness).

Q235B is one of the most commonly used and representative material grades in channel steel.
