Sandblasting and Painting

DesignCraft LTD provides comprehensive surface preparation, sandblasting, and industrial painting services for storage tanks, pressure vessels, pipelines, structural steel, and mechanical equipment. Our goal is to deliver long-lasting protection against corrosion, weathering, chemical exposure, and operational wear—ensuring maximum service life and reduced maintenance costs for all industrial assets.

We follow international coating standards and use world-class paint systems to guarantee performance and durability in the harshest environments, including refineries, chemical plants, fuel terminals, power stations, and offshore/onshore facilities.

We perform professional abrasive blasting to achieve the required cleanliness level according to ISO 8501-1 and SSPC standards:

Surface Cleanliness Grades

SA 2 – Thorough blast cleaning, SA 2.5 – Near-white metal blast cleaning (most common for industrial tanks)

SA 3 – White metal blast cleaning (critical service)

Why Sandblasting Is Essential

Proper surface preparation is the most important step in any coating system. Sandblasting removes:

Rust and corrosion

Old paint and coatings

Weld slag and heat tint

Scale, oil, and contaminants

This creates a clean, roughened surface profile, allowing coatings to bond and ensuring long-term performance.

Abrasives We Use

Depending on project requirements:

Garnet

Copper slag

Steel grit

Aluminum oxide, Glass beads (for stainless steel)

Equipment & Capabilities, High-capacity compressors

Pressurized blasting pots, Closed and open blasting systems, On-site and workshop blasting, Dust collection and safety systems
