Zinc Plated

Zinc plating is an electroplated surface finish that applies a thin layer of zinc to steel screws, providing a basic yet effective barrier against rust and corrosion. It offers a bright, silvery appearance and serves as a sacrificial layer, where the zinc corrodes first to protect the underlying steel. This process is valued for its excellent cost-performance ratio in controlled environments.

Product details

Typical Applications:

Indoor & General Assembly: Widely used in interior furniture, electronics, light fixtures, and machinery assembled for indoor use where exposure to moisture is minimal.
Fast Consumer Goods: Common in appliances, toys, and DIY kits where a combination of corrosion resistance, aesthetics, and low cost is prioritized.
Temporary or Protected Structures: Suitable for internal components of outdoor equipment that are shielded from direct weather exposure.

Our Finishing & Custom Capabilities:
Our zinc plating process is controlled to deliver consistent coverage and performance. Key options and specifications include:

Coating Thickness: Standard plating (typically 5-8μm) to meet common specifications such as ASTM B633.
Chromate Conversion Coatings: Optional colored finishes including clear (blue-bright), yellow (iridescent), or black chromate for enhanced corrosion resistance and specific aesthetic requirements.
Material Compatibility: Applied to a range of base materials including carbon steel screws, with options for subsequent wax or sealant treatments for improved performance.

This finish provides a reliable and economical first line of defense against oxidation, making it a versatile choice for a broad spectrum of general-purpose fastening needs.
