Hot Rolled Unequal Angle Steel

Ruicheng Steel is a premier manufacturer of Hot Rolled Unequal Angle Steel, a specialized L-shaped structural steel section where the two legs are of different lengths. Unlike equal angles, the unequal design offers unique structural advantages, making it ideal for engineering projects requiring specific load-bearing ratios and asymmetrical connections.

Manufactured from high-grade carbon steel billets through a precise hot-rolling process, our unequal angle bars exhibit excellent strength, durability, and weldability. We strictly adhere to international standards such as GB/T 9787, JIS G3192, and EN 10025 to ensure every piece meets your project’s rigorous demands.

Whether you need Black (Bare) finish for further fabrication or Hot-Dip Galvanized coating for superior corrosion resistance, Ruicheng Steel provides a one-stop solution for your structural steel needs.
