Concrete Cylinder:
Our product is designed with cutting-edge, customized quenched and tempered heat rail tubes, offering unparalleled performance beyond typical market standards. The product material boasts a hardness that exceeds 260HB, surpassing the national benchmark of 230HB, with a yield hardness reaching an impressive 680 ± 10, far above the standard of 450. Additionally, it offers a remarkable tensile strength of 920, clearly exceeding the national standard of 680. Moreover, the end face shrinkage rate of 60, compared to the national standard minimum of 40, highlights its extraordinary construction and resilience.
The sophisticated craftsmanship and honing techniques are essential in delivering superior-quality concrete cylinders. Our pre-electroplating honing process is critical as it significantly impacts the overall electroplating quality. We meticulously ensure the inner hole roundness is precisely controlled within 0.03mm, achieving an extraordinary roughness of R0.01, resulting in a splendid mirror-like finish. By integrating the advanced Hc3mS chrome plating technology from Anmet, we ensure a uniform, dependable coating with a precision thickness of 0.01, enhancing durability and performance.
Our advanced painting process involves applying a high-quality anti-rust primer followed by a durable topcoat, culminating in a robust paint film thickness of 80um ± 10. The paint's adhesion strength rigorously adheres to the demanding GB/T1720 standard level II, ensuring enduring protection and exceptional longevity.
