Concrete Cylinder:
Our product leverages advanced, customized quenched and tempered heat rail tubes, delivering unmatched performance compared to typical market offerings. With a material hardness that surpasses an impressive 260HB (far exceeding the national standard of ≥ 230HB), a robust yield hardness of 680 ± 10 (national standard ≥ 450), and a formidable tensile strength of 920 (national standard ≥ 680), this product is truly exceptional. Furthermore, an end face shrinkage rate of 60 (national standard ≥ 40) further emphasizes its outstanding build quality.
The sophisticated process and honing techniques are absolutely crucial in crafting high-quality concrete cylinders. The honing quality prior to electroplating is incredibly important, as it directly influences the superior final electroplating quality. Our meticulous honing process ensures the inner hole roundness is tightly controlled within an astounding 0.03mm, achieving an exceptional roughness of R0.01. This results in the inner hole attaining a stunning mirror-like finish. By incorporating the groundbreaking Hc3mS chrome plating technology from Anmet, we guarantee a uniform and reliable coating within a precise 0.01 thickness.
We utilize a superior paint process that includes an anti-rust primer followed by a topcoat, achieving a robust paint film thickness of 80um ± 10. The adhesion strength of our paint meets the stringent GB/T1720 standard level II, ensuring unparalleled long-lasting protection and durability.
