Embark on a seamless journey with our meticulously crafted production process. Begin with the finest raw material (steel coil), which is expertly uncoiled, then precision sheared and seamlessly butt-welded for optimal integrity. The material accumulates before undergoing non-power leveling, ensuring a flawless form. Next, it undergoes mill-forming where high-frequency welding takes place, ensuring a robust bond. Burrs are meticulously removed from the outside of the weld seam, followed by a cooling phase that ensures structure stability. The process continues with precise sizing and rough straightening to maintain the perfect form. Finally, it is cut to a fixed length and delivered to the run-out table, ready for the next stage of excellence.
