Concrete Cylinder:
Our product is engineered with advanced, bespoke quenched and tempered heat rail tubes, elevating performance beyond conventional market standards. With an impressive hardness exceeding 260HB, far surpassing the national benchmark of 230HB, a formidable yield hardness of 680 ± 10, outstripping the national requisite of 450, and an exceptional tensile strength of 920, compared to the standard 680, this product is truly a class apart. Furthermore, the end face shrinkage rate of 60, greatly surpassing the national standard of 40, highlights its outstanding structural integrity and craftsmanship.
Our sophisticated manufacturing process and precision honing techniques are crucial in crafting high-quality concrete cylinders. The honing quality prior to electroplating is of paramount importance, as it directly impacts the final electroplating excellence. Our meticulous honing process ensures the inner hole roundness is precisely maintained within 0.03mm, achieving an extraordinary roughness of R0.01. This meticulous attention results in the inner hole boasting a mirror-like sheen. By integrating the cutting-edge Hc3mS chrome plating technology from Anmet, we ensure a uniform, robust, and reliable coating with a precision thickness of 0.01.
Our superior painting process encompasses an anti-rust primer followed by a premium topcoat, culminating in a resilient paint film thickness of 80um ± 10. The adhesion strength of our protective paint conforms to the rigorous GB/T1720 standard level II, promising enduring protection and unrivaled durability.
