Concrete Cylinder:
Our product leverages cutting-edge, tailor-made quenched and tempered heat rail tubes to deliver unmatched performance, surpassing standard market options. Featuring material hardness levels exceeding 260HB (compared to the national standard of ≥ 230HB), a yield hardness of 680 ± 10 (well above the national standard of ≥ 450), and a tensile strength reaching an impressive 920 (far surpassing the national standard of ≥ 680), this product is truly exceptional. Moreover, the end face shrinkage rate of 60 (national standard of ≥ 40) further highlights its outstanding craftsmanship and superior build quality.
The sophisticated process and honing techniques are central to crafting top-tier concrete cylinders. The honing quality before electroplating is of paramount importance, as it directly impacts the final electroplating results. Our meticulous honing processes ensure the inner hole roundness is strictly maintained within 0.03mm, achieving an astonishing roughness of R0.01, resulting in a mirror-like finish. By integrating the pioneering Hc3mS chrome plating technology from Anmet, we guarantee a consistently uniform and dependable coating, precisely within a 0.01 thickness.
We employ an advanced paint process featuring an anti-rust primer, followed by a resilient topcoat, resulting in a robust paint film thickness of 80um ± 10. Our paint's adhesion strength adheres to the rigorous GB/T1720 standard level II, ensuring enduring protection and remarkable durability.
