Concrete Cylinder:
Our product leverages advanced, customized quenched and tempered heat rail tubes, delivering unparalleled performance that far surpasses typical market offerings. Boasting a material hardness exceeding 260HB (national standard ≥ 230HB), a yield hardness of 680 ± 10 (national standard ≥ 450), and an impressive tensile strength of 920 (national standard ≥ 680), this product truly stands out in terms of durability and reliability. Furthermore, an end face shrinkage rate of 60 (national standard ≥ 40) underscores its exceptional build quality, making it a top-tier choice for demanding applications.
Our sophisticated process and honing techniques are paramount in crafting these high-quality concrete cylinders. The honing quality before electroplating is critical, as it directly impacts the final electroplating outcome. Through our meticulous honing, we ensure the inner hole roundness is precisely controlled within 0.03mm, achieving an extraordinary roughness of R0.01. This results in the inner hole attaining a mirror-like finish. By incorporating the cutting-edge Hc3mS chrome plating technology from Anmet, we provide a uniform and reliable coating with a precise thickness of 0.01, ensuring consistent performance and longevity.
We employ a premium paint process that starts with an anti-rust primer, followed by a topcoat, resulting in a robust paint film thickness of 80um ± 10. The adhesion strength of our paint meets the stringent GB/T1720 standard level II, ensuring long-lasting protection and unmatched durability. This superior paint process guarantees that our products maintain their integrity and appearance even in the harshest environments.
