1 / 5
Made from high-grade ZAMAK 5 (ZA-8) alloy, ensuring excellent tensile strength, durability, and long-term performance under stress.
Manufactured using advanced die-cast molding technology for complex, consistent geometries with tight tolerances and a smooth, clean surface finish, ready for further processing.
Tailor the stem to your exact needs. Customize the clamp diameter, length, angle, and hole patterns. We can adapt the design to your specific mechanical and aesthetic requirements.
Available in Polished, Chrome Plating, Powder Coating, PVD coatings like Gold, Black, Gunmetal, and more. All finishes pass rigorous salt spray tests (e.g., 96+ hours).
The zinc alloy base combined with high-quality plating/coating provides outstanding resistance to rust, tarnish, and wear, suitable for indoor and outdoor use.
Designed for straightforward assembly, featuring precisely machined clamping surfaces and clean bolt hole threads for a secure and reliable fit.

With the whole process of moulding, die-casting, machining, polishing, plating/powder coating/painting, inspection, assembly and shipment, we can strictly control every step of handle production to ensure quality and improve product qualification rate.
We provide OEM/ODM services for many famous international brands in Europe and America — for example, TOTO, Dornbracht, Roca, KLUDI.
Plating Standard We strictly control the thickness of plating layer of copper, nickel and chrome: Cu ≥ 15μm, Ni ≥ 10μm, Cr ≥ 0.15μm. Products can pass neutral 240 hours or acidic 48 hours salt spray test. We also customize handles for salt spray testing in excess of neutral 480 hours. We promise never to use return material directly for die-casting production.
