Concrete Cylinder:
Our product boasts cutting-edge, fully customized quenched and tempered heat rail tubes, providing performance that far surpasses standard market alternatives. With a remarkable material hardness exceeding 260HB, well above the national standard of 230HB, coupled with an impressive yield hardness of 680 ± 10 (national standard ≥ 450), and a tensile strength soaring at 920 (national standard ≥ 680), this product truly excels. Furthermore, with an end face shrinkage rate of 60 (national standard ≥ 40), it highlights its extraordinary build quality.
The sophisticated process and honing techniques are pivotal in crafting exceptionally high-quality concrete cylinders. The honing quality before electroplating is vital, as it directly impacts the ultimate electroplating quality. Our meticulous honing ensures the inner hole roundness is precisely controlled within a mere 0.03mm, achieving an extraordinary roughness of R0.01, resulting in the inner hole attaining a mirror-like finish. By incorporating the advanced Hc3mS chrome plating technology from Anmet, we ensure a uniformly reliable coating with a precise 0.01 thickness.
We implement a superior paint process featuring an anti-rust primer followed by a topcoat, culminating 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 lasting protection and outstanding durability.
