Our sand blasting service is a vital step in preparing steel surfaces for protective coatings, especially for heavy structural steel used in industrial, marine, and harsh environmental conditions. Proper surface preparation through sand blasting ensures superior paint adhesion, extends the lifespan of coatings, and significantly improves corrosion resistance.

What is Sand Blasting?

Sand blasting (also known as abrasive blasting) is the process of propelling fine abrasive particles at high velocity to clean, roughen, or profile steel surfaces. It removes contaminants such as:

• Rust and mill scale
• Old paint layers
• Dirt, grease, and welding slag
• Other surface impurities

This process results in a clean, textured surface ideal for coating applications.

Surface Preparation Standards

We achieve surface cleanliness and profile depth as per internationally recognized standards including:

• SA 2 to SA 2.5 (Near White to White Metal Blast Cleaning) as per ISO 8501-1 and SSPC-SP10 standards
• Surface profile depth maintained between 50 to 75 microns for optimal coating adhesion
• Visual and tactile inspection to ensure no visible rust, oil, or dust remains
• Control of dust and environmental factors to maintain surface integrity

Abrasive Media Used

Depending on the project requirements and environmental considerations, we use a variety of abrasive materials:

• Silica sand (where allowed)
• Garnet abrasive – eco-friendly and recyclable, preferred for most industrial work
• Steel grit and shot – for heavier surface profiling and recycling within closed systems
• Aluminum oxide and glass beads – for specialized finishes

We ensure selection of the right abrasive for the substrate and coating system.
