Concrete Cylinder:
Our product takes full advantage of cutting-edge, customized quenched and tempered heat rail tubes, ensuring performance excellence that eclipses standard market options. With a material hardness surpassing 260HB (compared to the national standard of ≥ 230HB), a yield hardness of 680 ± 10 (national standard of ≥ 450), and a tensile strength of 920 (national standard of ≥ 680), our product clearly distinguishes itself with outstanding durability and resilience. Furthermore, an end face shrinkage rate of 60 (national standard ≥ 40) further highlights its remarkable construction quality and robustness in demanding environments.
The advanced process and precision honing techniques are integral to the creation of top-tier concrete cylinders. The honing quality before electroplating is vital, as it significantly impacts the final plating quality. Our painstaking honing processes ensure the inner hole roundness is precisely kept within 0.03mm, achieving a remarkable roughness of R0.01, resulting in a mirror-like finish inside the cylinder. By integrating the cutting-edge Hc3mS chrome plating technology from Anmet, we guarantee a consistent and dependable coating with a perfect thickness of 0.01, enhancing both performance and longevity.
We implement an exceptional paint process, beginning with a fortified anti-rust primer followed by a resilient topcoat, resulting in a durable paint film thickness of 80um ± 10. The paint's adhesion strength complies with the rigorous GB/T1720 standard level II, ensuring enduring protection and longevity against environmental factors.
