Ningbo Qihong has been manufacturing stainless steel materials for many years, and this stainless steel strip coil has always been our flagship product. Its quality has been rigorously tested in the market. We never compromise on raw materials, using only genuine, high-quality stainless steel. Commonly used steel grades such as 201, 304, 316L, and 430 are all in stock. For special requirements, we can also meet multiple series such as 200, 300, and 400.
We also closely monitor the production process. Cold rolling, annealing, leveling, and slitting—every process is carried out to precise standards, with strict quality control throughout. The resulting strip coils are not only high in strength and corrosion-resistant, but also exceptionally easy to process, making them highly regarded in the industrial manufacturing sector.
The most outstanding feature of Qihong's stainless steel strip coil is its stable performance. Whether subjected to significant external forces or exposed to humid environments and acidic or alkaline substances, it is not easily deformed or rusted, and it remains reliable even under harsh working conditions.
Furthermore, it boasts exceptional processing adaptability, easily handling common processes such as cutting, stamping, and welding. Whether producing large components or precision parts, it meets all requirements. Moreover, our strip rolls come in a wide range of specifications; width and thickness can be adjusted as needed, and the surface can be treated to achieve various effects, essentially matching any production requirement.
Most importantly, thanks to our company's advanced equipment and professional testing processes, the dimensional accuracy and surface quality of each strip roll are guaranteed, ensuring your peace of mind upon receipt.
