Metal Coating and Finishing Companies in the United States

Surface finishing and protective coatings are critical steps in the production process for parts used in industries like defense, aerospace, transportation, and heavy machinery. Whether you’re seeking corrosion resistance, cosmetic appeal, or enhanced wear protection, RFQ USA connects buyers with verified U.S.-based companies that specialize in all forms of metal coating and finishing. From precision anodizing and black oxide to hot dip galvanizing and electroless nickel, our platform makes it easy to locate the right service provider.

All companies listed on RFQ USA have been reviewed for quality, industry certifications, and capabilities. Many of them hold ISO 9001, AS9100, ITAR registration, and Nadcap accreditations, helping you meet both internal standards and customer or contract requirements.

ISO, ASME, and Nadcap Certified Finishing Providers

You don’t have to compromise on quality to meet project deadlines. Our directory includes companies with internationally recognized certifications, including:

• ISO 9001:2015 for consistent quality management
• ASME certification for pressure-related finishing applications
• Nadcap accreditation for aerospace-specific coating and heat treatment standards
• ITAR registration for secure handling of defense-related components

These designations mean you’re working with professionals who understand documentation, traceability, and regulatory compliance, not just surface treatment.

Black Oxide, Anodizing, and Electroplating Services

RFQ USA members provide a wide range of metal treatment options to solve technical and performance challenges across industries. Coating and finishing services include:

• Black Oxide Coating, which enhances corrosion resistance and reduces reflectivity without chipping or peeling
• Anodizing for increased surface hardness and aesthetic appeal, particularly for aluminum parts
• Electroplating, including zinc, nickel, copper, and precious metal options for appearance or conductivity
• Passivation and phosphate coatings for enhanced rust resistance and paint adhesion

If you’re unsure which finish best suits your application, our members can assist with material selection, spec review, and production planning.

Hot Dip Galvanizing and Post-Processing Services

Several companies on our platform offer hot-dip galvanizing services that meet ASTM A123 and A153 standards. Galvanizing provides long-lasting protection for steel in outdoor, marine, and corrosive environments and is often used in construction, agriculture, and infrastructure applications. Some providers also offer post-processing services such as re-machining or assembly after coating, helping maintain tolerances and part functionality even after metal treatment.

These turnkey options simplify your supply chain and reduce the risk of delays or rework during downstream operations.

ITAR Registered and Aerospace-Grade Finishing Services

Defense and aerospace projects often come with tight tolerances and strict compliance requirements. RFQ USA features metal finishing shops that are ITAR compliant and equipped to meet the demands of U.S. military and defense contractors. For aerospace parts, Nadcap-accredited processes like aluminum anodizing, cadmium plating, and heat treatment are available. These services help ensure product integrity while maintaining eligibility for high-stakes projects.
