Concrete Cylinder:
Our product leverages cutting-edge, tailored quenched and tempered heat rail tubes, elevating its performance far above the typical market offerings. With its remarkable material hardness exceeding 260HB, surpassing the national standard of 230HB, and a yield hardness of 680 ± 10, well above the national standard of 450, it clearly sets a new benchmark. The tensile strength of 920, compared to the national standard of 680, is another testament to its superior quality. Notably, the end face shrinkage rate stands at an impressive 60, far outstripping the national standard of 40, highlighting its unmatched construction excellence.
The advanced processes and honing techniques are essential in crafting concrete cylinders of unparalleled quality. The meticulous honing process before electroplating is vital as it has a direct impact on the final electroplating quality. Our precision honing rigorously maintains the inner hole roundness to within 0.03mm, achieving an extraordinary roughness of R0.01, resulting in a stunning mirror-like inner finish. By employing the innovative Hc3mS chrome plating technology from Anmet, we ensure a consistent and reliable coating with a precise thickness of 0.01, reinforcing our commitment to excellence.
Our exceptional paint process begins with a superior anti-rust primer and concludes with a topcoat, forming a durable paint film thickness of 80um ± 10. The paint's adhesion strength meets the rigorous GB/T1720 standard level II, promising enduring protection and resilience for the product's lifecycle.
