Concrete Cylinder:
Our premium offering harnesses cutting-edge, tailored quenched and tempered heat rail tubes, ensuring remarkable performance surpassing standard market alternatives. Boasting a material hardness surpassing 260HB (national standard ≥ 230HB), a yield hardness of 680 ± 10 (national standard ≥ 450), and a tensile strength of 920 (national standard ≥ 680), this product truly excels. Furthermore, the end face shrinkage rate of 60 (national standard ≥ 40) highlights its outstanding construction quality.
The advanced process and honing techniques are central to fabricating top-tier concrete cylinders. The honing quality before electroplating is vital, as it has a direct impact on the ultimate electroplating quality. Our precise honing ensures the inner hole roundness is meticulously managed within 0.03mm, achieving a remarkable smoothness of R0.01. This results in the inner hole obtaining a mirror-finish. By integrating the cutting-edge Hc3mS chrome plating technology from Anmet, we promise a consistent and dependable coating with a precision thickness of 0.01.
We employ an advanced painting process that includes an anti-rust primer followed by a high-performance topcoat, achieving a durable paint film thickness of 80um ± 10. The adhesion strength of our paint complies with the rigorous GB/T1720 standard level II, ensuring enduring protection and resilience.
