Certifications and Standards

DELTA®-TONE/DELTA®-SEAL Coating System Certified

Meets CQI-12 Coating System Standards

Overview

Fasteners are exposed to various environmental stresses like heat, cold, rain, and wind, making corrosion resistance critical. RFI employs advanced zinc flake-based coating systems like DELTA®-TONE and DELTA®-SEAL, which provide superior corrosion protection without harmful chromium(VI) content.

Heat Treatment

Step-by-Step Process

Base Coating

Fasteners receive a zinc flake base coat to provide the primary corrosion protection.

Top Coating

A top coat is applied to enhance the fastener’s resistance to environmental factors and chemicals.

Final Inspection

Fasteners are inspected for coating thickness and uniformity.

Why This Process?

Our coating systems provide long-term corrosion protection, ensuring that fasteners can withstand harsh environmental conditions over extended periods. This enhanced protection reduces the likelihood of damage, ensuring the integrity and reliability of the fasteners in demanding applications. Whether in industrial, marine, or construction environments, these coatings ensure that fasteners remain durable and effective. In addition to their protective benefits, our coating systems are environmentally friendly, being chromium(VI)-free. This not only aligns with global environmental standards but also makes our fasteners a sustainable option. By reducing the need for frequent maintenance and replacements, the coatings contribute to cost-efficiency over the long term, making them an ideal choice for projects that require both durability and sustainability.
