1. Material Grade & Corrosion Resistance Performance
Material selection and surface finishing are essential for ensuring long-term operational durability across commercial and industrial environments:
High-Strength Die-Cast Zinc Alloy (ZDC): The housing, handle, and internal structural components are manufactured from premium die-cast zinc alloy, offering exceptional mechanical rigidity, impact resistance, and structural stability under heavy daily use.
Bright Chrome Plating Surface Finish: Finished with a high-luster electroplated chrome coating in a sleek silver tone, the lock forms a durable protective barrier against daily wear, fingerprints, and atmospheric oxidation.
Atmospheric Adaptability & Salt Spray Performance: Rigorously tested to withstand standard industrial and outdoor humidity levels, preventing premature rust formation on the zinc substrate.
IP Rating Enclosure Compatibility: Designed with precision tolerances and smooth operation to integrate seamlessly with enclosure gasketing systems, helping cabinets maintain high-performance dust-tight and water-resistant protection grades when properly installed.
