Surface Preparation & Industrial Coating

Protective Coating & Surface Treatment Solutions

Our Surface Preparation & Coating Department enhances the durability, corrosion resistance, and finish of all fabricated steel, piping, tanks, and equipment. Each treatment is engineered to meet specific environmental challenges, project conditions, and client standards across Qatar and the GCC.

We apply industry-standard surface treatment tailored to:

Steel structures, piping systems, tanks, and industrial equipment

Project specifications and environmental exposure

Client standards and regional climate conditions

Compliant with Qatar-specific requirements:

QatarEnergy (QE)

QatarEnergy LNG (QE LNG)

Ashghal (Public Works Authority)

Kahramaa (Qatar General Electricity & Water Corporation)

Coating designs based on:

ISO 12944 exposure categories: C1–C5, CX, Im2

Harsh conditions: Coastal, desert, offshore, industrial, chemical, high UV & sandstorms

Surface Preparation & Coating Capabilities

We combine mechanical surface treatments with advanced coating systems to ensure long-term protection and aesthetic value. All processes are aligned with international standards and approved project specifications.

Surface Preparation:

Sand Blasting: SA 2.5 / SA 3 finish to remove rust, scale, and contaminants (QatarEnergy, QE LNG, Ashghal, Kahramaa compliant)

Degreasing & Cleaning: Eliminates oils and residues before coating

Surface Profiling: Prepares surface roughness for optimal coating adhesion

Industrial Coating Applications:

Epoxy Coating: High-performance corrosion resistance

Enamel Painting: Durable, clean finish for exposed components

Hot-Dip Galvanizing: Zinc-coating for superior corrosion protection; coordinated with certified vendors

Specialized Coatings: Fire-retardant, chemical-resistant, or client-specified solutions

Environment-Specific Coatings: C3–C5M, C5I, CX, Im2 categories for harsh exposure zones

Inspection, Testing & Compliance Assurance

Every coating application is validated through a rigorous inspection process to guarantee adherence to international, local, and client-specific standards. Documentation and QA/QC certifications are provided for all completed works.

Quality Control & Testing:

DFT (Dry Film Thickness) Checks: Ensures required coating thickness

Adhesion Testing: Verifies strong bonding between coating and substrate

Holiday Testing: Detects pinholes or gaps in the coating

Surface Profile Verification: Confirms abrasive blasting meets required roughness (per QE, LNG, Ashghal)

Final QA/QC Certification: Documentation ready for project handover

Standards & Compliance:

ISO 12944 – Corrosion protection of steel structures

SSPC-SP standards for surface prep

Exposure categories: C1–C5, CX, Im2 (coastal, desert, offshore, chemical, industrial)

Full compliance with QatarEnergy, QE LNG, Ashghal, Kahramaa, and client-specific coating schemes
