Zinc Electroplating

Lone Star’s zinc electroplating line provides quick turnaround and cost effectiveness for your plated bolt requirements. Our electroplating line is compliant to ASTM B 633 SC-2 Type-3 Conversion standards, and utilizes a revolutionary clear trivalent chromate conversion coating, allowing Lone Star to increase performance and production, while maintaining employee safety and remaining compliant to environmental requirements. (This includes the European Directives RoHS (Restriction of Hazardous Substances) and ELV (End of Life Vehicle), which became binding in Europe in July of 2006, and adopted in the state of California in January 2007).

Our zinc plating process, with clear trivalent conversion, offers:

• Hexavalent Chrome Free processing eliminates the toxic chemicals found in yellow chromate.
• Excellent Corrosion Resistance—Exceeding that of yellow chromate, and achieving 200-400 hours to white corrosion in ASTM B-117 Salt Spray.
• Increased Temperature Tolerance to 300º-400º F for many hours with no effect on corrosion resistance or color.
• Cost Effective - This new clear chromate costs no more than yellow chromate.
• Torque and Tension Fluid - Lone Star adds an additional topcoat solution to add lubricity at no cost to our customers.

Our Standard zinc plating specification is ASTM B 633 SC-2 Type-3 Conversion
