Surface Coating & Anti-Corrosion Services - Black Coating

Black coating is a high-quality protective finish applied to steel pipes, structural steel, and metal components. This coating is typically a black varnish, black oxide, or black epoxy layer, providing both corrosion protection and a visually uniform finish. It is widely used in industries where moderate protection against rust and environmental factors is required, particularly during storage, transportation, and fabrication processes.

Technical Features

Uniform Surface Finish: The black coating ensures smooth, even coverage with no peeling or blistering, enhancing both aesthetics and protective performance.

Corrosion Prevention: Forms a protective barrier that slows down oxidation and rust formation, especially in indoor or controlled environments.

Adhesion Friendly: Compatible with welding, bending, and other fabrication processes without cracking or flaking.

Durable & Stable: Resistant to light abrasion, handling damage, and standard storage conditions.

Before & After Comparison

Before Coating: Bare metal surface, prone to rust and corrosion

During Coating: Even coverage, smooth and uniform surface.

After Coating: Black finish with enhanced corrosion and wear resistance.

Applications & Performance

Typical Applications: Steel pipes, steel plates, structural components, machinery parts, and more.

Service Life: Generally 10-15 years for outdoor environments (depending on coating thickness, environment, and maintenance).

Performance: Rust-proof, corrosion-resistant, wear-resistant, aesthetically sleek.

Certifications Required: Can provide relevant quality certificates conforming to ISO, ASTM, or customer-specific standards.

Applications

Mechanical Pipes: Used in low-pressure piping systems for mechanical and industrial applications.

Structural Tubes & Beams: Suitable for H-beams, I-beams, and square or rectangular hollow sections in building frames and industrial structures.

Round & Square Hollow Sections: Ideal for tubular steel products used in scaffolding, fencing, automotive frames, and machinery parts.

Temporary Protection: Provides effective protection during shipment and storage before final surface treatments such as galvanization or painting.

Color Customization

Standard Color: Black (RAL 9005)

Custom Colors: Available according to RAL color charts, customer samples, or specific project requirements.

Note: Custom colors may depend on order quantity and application conditions.

Available Certificates

Coating Material Certificates: MSDS, environmental compliance, anti-corrosion testing reports.

Coating Quality Certificates: Thickness inspection reports, adhesion test certificates.

Packaging & Transportation

Packaging Method: Wrapped in waterproof cloth and secured on pallets.

Transportation Options:

Container Shipping: Suitable for long-distance sea transport, protects against rain and moisture.

Bulk Transport: Suitable for short-distance or large-volume shipments, with protective wrapping.

Conclusion

:Black coating (Black Vanish / Black Paint) is an economical and reliable solution for protecting steel surfaces against corrosion and handling damage. It is a practical choice for industrial, mechanical, and structural applications, ensuring steel products remain durable, clean, and ready for further fabrication or installation.
