Premium Zinc Alloy Construction

Made from high-grade ZAMAK 5 (ZA-8) alloy, ensuring excellent tensile strength, durability, and long-term performance under stress.

High-Precision Die-Casting

Manufactured using advanced die-cast molding technology for complex, consistent geometries with tight tolerances and a smooth, clean surface finish, ready for further processing.

Extensive Customization (OEM/ODM)

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.

Superior Surface Finish Options

Available in a variety of finishes including Polished, Chrome Plating, Powder Coating, PVD (Physical Vapor Deposition) coatings like Gold, Black, Gunmetal, and more. All finishes are designed to pass rigorous salt spray tests (e.g., 96+ hours).

Robust Corrosion Resistance

The zinc alloy base combined with high-quality plating/coating provides outstanding resistance to rust, tarnish, and wear, making it suitable for indoor and outdoor use.

Easy Installation & Compatibility

Designed for straightforward assembly, often featuring precisely machined clamping surfaces and clean bolt hole threads for a secure and reliable fit.

Full-Service OEM Partner: From mold design and prototyping to final assembly and packaging.

Stringent QC: Every piece undergoes rigorous inspection to ensure dimensional accuracy and finish quality.

Competitive Pricing: Cost-effective solutions without compromising on quality, ideal for bulk orders.

Ready to customize your handlebar stems? Send us your technical drawings, 3D files, or samples. Our engineering team will review your needs and provide a competitive solution.

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.

Actually we provide OEM/ODM services for many famous international brands in Europe and America. For example, TOTO, Dornbracht, Roca, KLUDI.

We strictly control the thickness of plating layer of copper, nickel and chrome, usually our plating thickness is: Cu ≥ 15um, Ni ≥ 10um, Cr ≥ 0.15um, and can pass neutral 240 hours or acidic 48 hours salt spray test. We also customize your handles for salt spray testing in excess of neutral 480 hours. And we promise never to use the return material directly for die-casting production.

Sincerely welcome you to call us and visit our factory!
