Concrete Cylinder:
Revolutionizing the industry, our product utilizes top-tier, tailored quenched and tempered heat rail tubes to deliver unparalleled performance. Compared to common market products, ours shines with its material hardness surpassing 260HB, eclipsing the national standard of ≥ 230HB. The yield hardness is a remarkable 680 ± 10, well above the national standard of ≥ 450, while the tensile strength impressively reaches 920, far exceeding the national benchmark of ≥ 680. Moreover, the outstanding end face shrinkage rate of 60, over the national standard of ≥ 40, highlights the exceptional craftsmanship embedded in this superior product.
The artful process and advanced honing techniques play a critical role in the creation of our premium concrete cylinders. Prior to electroplating, honing quality is vital, as it significantly affects the ultimate quality of electroplating. Our precise honing ensures the inner hole roundness is meticulously maintained within 0.03mm, achieving a remarkable roughness of R0.01, resulting in a stunning mirror-like inner finish. By integrating the cutting-edge Hc3mS chrome plating technology from Anmet, we ensure a consistent and trustworthy coating with a precision thickness of 0.01.
Our advanced paint process begins with an anti-rust primer, followed by a durable topcoat, resulting in a resilient paint film thickness of 80um ± 10. Our paint's adhesion strength aligns with the rigorous GB/T1720 standard level II, providing enduring protection and robustness.
