At the steel coil yard in Shanghai Port, HXH STEEL’s inspectors are applying millimeter-level rigor. This careful attention to every detail—thickness, surface quality, and weight—reflects the company's unwavering commitment to delivering highly qualified products that meet international standards.
Our quality control process is rigorous and systematic. Inspectors utilize calibrated professional calipers for sample thickness measurement, ensuring dimensional tolerance adheres strictly to industry and customer specifications. Surface quality is assessed through visual inspection under controlled lighting and tactile checks to identify defects such as scratches, edge burrs, or signs of premature oxidation. Finally, coil weight is meticulously verified by cross-referencing coil ID marks and weighing records against the official Bill of Lading data, ensuring absolute transparency.
This "millimeter-level rigor" is a direct reflection of HXH STEEL’s advanced manufacturing confidence. Our coils are produced via multi-pass precision cold rolling, featuring real-time gauge control (AGC) to minimize deviation. We specifically optimize our annealing and skin-pass finishing processes to achieve the required surface smoothness, making the material ideally suited for demanding applications like deep drawing and precision stamping.
HXH STEEL’s coils are preferred in critical sectors due to their consistency and superior finish. The dimensional uniformity directly contributes to the load-bearing integrity and stability of heavy-duty warehouse racking systems. Furthermore, the flawless surface finish allows for direct, cost-saving application of protective coatings and paints on structural components, such as essential agricultural machinery parts. We ensure every carbon steel coil acts as a reliable cornerstone for our customers’ production chains.
