Anti-Corrosion Coating for Structural Steel

Multi-coat anti-corrosion systems that protect structural steel from rust in the UAE’s humid, salt-laden climate, applied by our certified crews to ISO 12944 specifications.

Mechanism

What it is and how it works

Steel left unprotected in the Gulf starts to rust within weeks. An anti-corrosion system seals the surface behind a sacrificial zinc-rich primer and layers of barrier coating, so moisture and salts cannot reach the metal, keeping the structure sound for decades

  • C4–CXUAE corrosivity (ISO 12944-2)
  • Sa 2½Blast-cleaning standard
  • 15–25+ yrsDesign durability targets

What it is

  • A multi-coat barrier systemPrimer, intermediate and topcoat work together to keep moisture, oxygen and salts away from the steel surface.
  • Built for the Gulf climateHigh humidity, airborne chlorides and strong UV make UAE coastal and industrial sites some of the most corrosive environments for steel.
  • The base for fireproofingIntumescent and cementitious fireproofing must sit on a compatible anti-corrosive primer, so the two systems are specified together.

How it works

  1. Clean surfaceAbrasive blasting removes rust and mill scale and creates an anchor profile for adhesion.
  2. Active primerA zinc-rich epoxy primer gives sacrificial (galvanic) protection to the steel.
  3. Barrier buildAn epoxy intermediate, often with micaceous iron oxide, adds thickness and blocks moisture paths.
  4. Weather shieldA polyurethane topcoat resists UV, keeps the colour and protects the layers beneath.
  5. Verified thicknessDry film thickness is measured coat by coat against the system specification.

Categories follow ISO 12944-2. The exact system, number of coats and dry film thickness depend on the corrosivity category, the required durability and the manufacturer's data sheet. Send us your specification and we will confirm the system for each area.

How we apply it

  1. Step 01

    Surface preparation

    • Degreasing, then abrasive blasting to Sa 2½ (ISO 8501-1)
    • Surface profile, dust and soluble salt checks before coating
  2. Step 02

    Priming

    • Zinc-rich epoxy primer applied soon after blasting, before flash rust forms
    • Steel temperature kept at least 3 °C above dew point
  3. Step 03

    Intermediate and topcoat

    • Epoxy intermediate for barrier build, stripe coats on edges and welds
    • Polyurethane topcoat where UV and weather exposure apply
    • Overcoat intervals kept within the data sheet limits
  4. Step 04

    Inspection

    • Dry film thickness recorded per coat and per member
    • Adhesion and holiday checks where the specification requires them
    • Primer compatibility confirmed if fireproofing follows

Each stage carries a hold point. Work does not move on until the previous coat is inspected and signed off, and the full record is issued to the consultant at handover.

Applications

Where anti-corrosion coating is used

Intumescent coatings are used as passive fire protection on structural elements — steel, timber and concrete — to delay structural collapse and hold escape routes open during a fire.

Structures and surfaces

  • Structural steelBeams, columns, trusses and connections, before or alongside fireproofing.
  • Pipe racks and pipeworkExposed process steel in plants where heat, chemicals and moisture combine.
  • Tanks and equipmentExternal surfaces of storage tanks, skids and steel housings.
  • Canopies and external steelShade structures, walkways and facades exposed to sun and salt air.

Industries and buildings

  • Industrial and energyPower and desalination plants, factories and oil and gas facilities.
  • Ports and coastal sitesWarehouses, terminals and seafront buildings in high-chloride environments.
  • Commercial and logisticsWarehouses, hangars, malls and towers with exposed or semi-exposed steel.

FAQs

Answers on curing time, retrofits, documentation, and Civil Defense approval scope.

Durability depends on the system and the environment. ISO 12944 sets durability ranges from low to very high, and a correctly specified multi-coat system on well-prepared steel is designed to protect for many years before major maintenance.

For most high-performance systems the steel is abrasive blasted to Sa 2½ to ISO 8501-1, checked for profile, dust and soluble salts, and primed before flash rust can form.

Yes. Intumescent and cementitious fireproofing need a compatible primer underneath. We confirm primer compatibility with the fireproofing manufacturer before work starts.

Seafront and port sites usually fall in ISO 12944 category C5, which typically calls for a zinc-rich epoxy primer, an epoxy intermediate and a polyurethane topcoat. The final system follows your project specification.

Yes. Dry film thickness and environmental conditions are recorded for every coat, and the inspection report is issued to the consultant and main contractor at handover.
