Concrete Cylinder:
Our product utilizes cutting-edge, customized quenched and tempered heat rail tubes, providing performance that is a step above standard market options. Boasting a material hardness surpassing 260HB compared to the national standard of ≥ 230HB, it also features a yield hardness of 680 ± 10, exceeding the national standard of ≥ 450. With a tensile strength reaching 920, well above the national standard of ≥ 680, this product is truly exceptional. Additionally, an end face shrinkage rate of 60, surpassing the national standard of ≥ 40, further highlights its remarkable construction quality.
The advanced process and honing techniques play a crucial role in creating premium concrete cylinders. The honing quality before electroplating is vital, as it significantly impacts the final electroplating outcome. Our careful honing ensures the inner hole roundness is stringently maintained within 0.03mm, achieving an outstanding roughness of R0.01. This results in the inner hole having a mirror-like sheen. By adopting the cutting-edge Hc3mS chrome plating technology from Anmet, we assure a consistent and dependable coating thickness of 0.01.
Our superior paint process involves an anti-rust primer, followed by a topcoat, resulting in a robust paint film thickness of 80um ± 10. The paint's adhesion strength aligns with the rigorous GB/T1720 standard level II, ensuring enduring protection and resilience.
