Concrete Cylinder:
Our product harnesses the power of cutting-edge, bespoke quenched and tempered heat rail tubes, elevating performance far beyond typical market standards. Boasting a material hardness that surpasses 260HB (with the national standard set at ≥ 230HB), a remarkable yield hardness of 680 ± 10 (national standard of ≥ 450), and an impressive tensile strength of 920 (national standard of ≥ 680), this product truly excels. The outstanding end face shrinkage rate of 60 (national standard of ≥ 40) further highlights its superior craftsmanship and durability.
The artful process and meticulous honing techniques are essential in producing top-tier concrete cylinders. The honing quality before electroplating is of utmost importance, as it significantly impacts the final electroplating result. Our precise honing technique ensures the inner hole roundness is maintained within a tight tolerance of 0.03mm, achieving an outstanding roughness of R0.01. This ensures the inner hole has a stunning mirror-like finish. By adopting the cutting-edge Hc3mS chrome plating technology from Anmet, we provide a consistent and trustworthy coating with a precise thickness of 0.01.
We employ an advanced painting process that begins with a high-quality anti-rust primer, followed by a durable topcoat, resulting in an impressive paint film thickness of 80um ± 10. Our paint's adhesion strength meets the rigorous GB/T1720 standard level II, offering unparalleled protection and enduring performance.
