CHINA UNITED IRON AND STEEL LIMITED is the manufacturer of hot-rolled flat bars. They stock a wide range of flat bars in different specification, standards, dimensions, thickness, shapes, and sizes. Their bar range has good tensile, yield and ultimate strength. They are manufacturing S355J2 flat bar which is prominent for engineering application. In addition, one can inquire for specific size bars for their application. These bars are manufactured from high-grade raw materials. Adding high tech machines and tools product become finest for engineering works. They have a skilled staff with years of experience which involves a manufacturing process. All the production process is done under the guidelines and supervision of experienced engineers.
The offered bars are available in different shapes such as square, rectangle, hex and cut dimensions. Few national and global standards are considered to meet the set up industrial norms. Moreover, special rolling mills make these bars precise. In addition of the heat treatment process, it gains more strength and durability. Matte finish, BA finish, hairline, sand brushing, NO1 finish, SATIN met coat makes it shinier and bright coat protects it from the rusting and oxidation. These are both magnetic and non-magnetic in nature. The grade is fully austenitic which is best for harsh environments.
Corrosion resistivity makes bars worthier for corrosive water even in salt water. In terms of heavy loads, these resist buckling and crushing that is the great option for architectural works. Mostly flat bars are used in automobile sectors due to its excellent formability with low machining cost. Also, it poses great workability towards pitting and crevice cracking at elevated temperatures.
The ordered product delivery to the clients within a week of order or may take more time for bulk orders. CHINA UNITED IRON AND STEEL LIMITED offers these bars at most reasonable rates and delivers them in form of bundles with the plastic coat or wooden boxes, crates to prevent them from damages. Additionally, S355J2 flat bar goes under various quality assurance test to provide assured product to clients. The test includes destructive, non-destructive test, mechanical test, IGC test, positive material test, chemical test, and third-party inspection.
