Wuxi Jin Ming Jian De Industry & Trade Co., Ltd. is one of the leading manufacturers and suppliers of q275 carbon steel sheet/plate in China. If you're going to wholesale the newest q275 carbon steel sheet/plate made in China, welcome to get pricelist from our factory. All customized products are with high quality and competitive price.
Q275 Steel is a medium-strength carbon structural steel grade under the Chinese GB/T 700 standard. Compared with Q235 steel, Q275 offers higher strength and hardness, making it suitable for applications requiring better load-bearing performance and wear resistance.
Q275 steel sheet and plate provide good machinability, weldability, and mechanical performance, and are widely used in mechanical manufacturing, industrial structures, agricultural equipment, and engineering components.
The "275" in Q275 refers to the minimum yield strength of 275 MPa.
