Concrete Cylinder:
Our cutting-edge product boasts advanced and bespoke quenched and tempered heat rail tubes, offering unparalleled performance that surpasses standard market options. With an impressive material hardness of over 260HB (far exceeding the national standard of ≥ 230HB), a yield hardness of 680 ± 10 (well above the national standard of ≥ 450), and a remarkable tensile strength of 920 (significantly higher than the national standard of ≥ 680), this product truly distinguishes itself. Moreover, the outstanding end face shrinkage rate of 60 (surpassing the national standard of ≥ 40) further highlights its exceptional build quality.
The advanced process and precision honing techniques are essential in crafting our high-quality concrete cylinders. The honing quality before electroplating is pivotal, as it directly impacts the final quality of electroplating. Our meticulous honing ensures the inner hole roundness is strictly maintained within 0.03mm, achieving a stunning roughness of R0.01, resulting in an inner hole with a mirror-like sheen. By incorporating the cutting-edge Hc3mS chrome plating technology from Anmet, we ensure a uniform and dependable coating with an exact thickness of 0.01.
Our product features a superior paint process that includes both an anti-rust primer and a topcoat, achieving a robust paint film thickness of 80um ± 10. The adhesion strength of our paint adheres to the rigorous GB/T1720 standard level II, guaranteeing enduring protection and durability.
