Surface Coating & Anti-Corrosion Services - Shot Blasting

Sand blasting, also known as shot blasting or abrasive blasting, is a critical surface preparation process for steel products. By using high-velocity abrasive particles, this treatment removes rust, mill scale, old coatings, and other surface contaminants, creating a clean and uniform substrate. It is an essential step to ensure long-lasting adhesion of subsequent protective coatings such as FBE, 3PE, 3PP, epoxy, and powder coatings.

Technical Features

Surface Cleanliness: Achieves surface cleanliness grades from Sa1 to Sa3 according to ISO 8501-1, suitable for industrial, marine, and pipeline applications.

Controlled Roughness: Produces a specified surface profile (roughness height) that enhances mechanical bonding of coatings, preventing delamination and extending service life.

Precision & Uniformity: Modern blasting equipment ensures even treatment across pipes, plates, and structural steel with no uneven spots or residual debris.

Versatile Abrasives: Can use sand, steel grit, glass beads, or other media depending on project requirements and environmental considerations.

Applications

Pipeline Industry: Prepares steel pipes for FBE, 3PE, or 3PP coatings, ensuring optimal anti-corrosion performance for onshore and offshore pipelines.

Structural Steel: Prepares beams, plates, and hollow sections for painting, powder coating, or galvanizing.

Mechanical & Industrial Parts: Cleans machinery components, fabricated steel parts, and storage tanks before coating or welding.

Restoration Projects: Removes rust, scale, and old paint from existing structures to extend their operational life.

Benefits for Clients

Enhanced Coating Adhesion: Creates an ideal anchor profile for coatings, significantly improving coating durability and reducing maintenance.

Corrosion Protection: By thoroughly cleaning the surface, subsequent coatings perform better, protecting steel against corrosion for decades.

Consistent Quality: ISO-standardized blasting ensures every batch meets precise surface cleanliness and roughness requirements.

Time & Cost Efficiency: Proper pre-treatment reduces coating failures, repairs, and downtime, saving time and costs in the long term.

Conclusion

Sand blasting / shot blasting is a foundational step in steel surface treatment. It ensures superior coating adhesion, long-term corrosion resistance, and consistent quality across pipelines, structural steel, and industrial components. At Royal Steel Group, we utilize state-of-the-art blasting facilities to deliver surfaces that meet international standards and client specifications.
