Concrete Cylinder:
Our product harnesses cutting-edge, customized quenched and tempered heat rail tubes, delivering superior performance that markedly surpasses standard market alternatives. The material boasts an impressive hardness exceeding 260HB (national standard ≥ 230HB), a yield hardness of 680 ± 10 (national standard ≥ 450), and a remarkable tensile strength of 920 (national standard ≥ 680). Moreover, the end face shrinkage rate of 60 (national standard ≥ 40) further exemplifies its extraordinary build quality.
The refined manufacturing process and precision honing techniques are essential in producing premium-quality concrete cylinders. The honing quality before electroplating is vital, as it directly impacts the final electroplating excellence. Our meticulous honing ensures the inner hole roundness is precisely controlled within 0.03mm, achieving an extraordinary roughness of R0.01. This results in the inner hole attaining a mirror-like finish. By integrating the advanced Hc3mS chrome plating technology from Anmet, we ensure a consistent and reliable coating with a precise thickness of 0.01.
We employ an exceptional paint process that involves an anti-rust primer followed by a topcoat, resulting in a robust paint film thickness of 80um ± 10. The adhesion strength of our paint adheres to the stringent GB/T1720 standard level II, guaranteeing enduring protection and remarkable durability.
