Concrete Cylinder:
Our product harnesses cutting-edge, tailor-made quenched and tempered heat rail tubes, delivering outstanding performance that surpasses typical market standards. Featuring a remarkable material hardness of over 260HB (compared to the national standard of ≥ 230HB), a yield hardness of 680 ± 10 (national standard ≥ 450), and a tensile strength of 920 (national standard ≥ 680), this accessory is engineered for excellence. Furthermore, the end face shrinkage rate of 60 (national standard ≥ 40) highlights its superior construction and performance.
The advanced processes and precise honing techniques are integral to the development of premium concrete cylinders. The honing quality before electroplating is paramount, as it directly affects the quality of the final electroplating. Our meticulous honing process ensures the inner hole roundness is strictly controlled within 0.03mm, achieving an extraordinary roughness of R0.01, resulting in a mirror-like finish. By integrating the innovative Hc3mS chrome plating technology from Anmet, we ensure a consistent and dependable coating with a precision thickness of 0.01.
Our painting process is unrivaled, comprising an anti-rust primer followed by a topcoat, achieving a durable 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 resilience.
