Industrial Coatings
Heavy-duty industrial protective coatings for structural steel, plant, tanks, and pipework in Accra and Tema — engineered to ISO 12944 corrosion categories C1 to CX, with ISO 8501-1 surface preparation and verified film build. Coralex Painters, since 1984.
An industrial coating is an engineered protective system for structural steel, plant, tanks, and pipework — specified to the corrosivity of its environment, applied over prepared steel, and verified coat by coat. Coralex Painters has carried specification-grade protective coating discipline across Accra, Tema, and Lomé since 1984, treating the coating as an asset-protection barrier rather than a finish.
Why Industrial Coatings Matter in Ghana’s Conditions
In an industrial facility the coating is rarely cosmetic — it is the barrier between a steel asset and the corrosion, chemical attack, and abrasion that would otherwise consume it. Structural steel, process tanks, pipework, and plant frames represent capital that depreciates the moment protection fails, and on the Ghanaian coast the rate of attack is unforgiving: saline air, high humidity, and the aggressive corrosivity of the Tema and Takoradi port environments drive steel toward rust far faster than an inland estate would.
Applied to the wrong category, over inadequately prepared steel, or to an unverified film thickness, a protective system fails as asset loss, unplanned shutdown, and a re-blast that costs more than the original specification. We specify the system to the measured corrosivity of the environment, prepare the substrate to standard, and verify every coat — so the asset is protected for its service life, not merely passed at handover.
Industrial Coating Systems We Offer in Accra
ISO 12944 Anti-Corrosion Systems
We classify the environment to ISO 12944 — from C1 inland-dry through C5 to CX — and build the multi-coat system to match: typically a zinc-rich epoxy primer for sacrificial protection, an epoxy MIO midcoat for barrier and chemical resistance, and a polyurethane topcoat for UV stability and finish where exposure demands it.
Marine & Coastal (C5-M) Systems
The coastal salt and humidity of Tema and Takoradi put port-adjacent steel at ISO 12944 C5-M — the marine category. We specify high-build zinc-rich and epoxy systems engineered for that corrosivity, where an inland-grade specification would fail early.
Tank, Pipework & Plant Coatings
Process and storage tanks, pipe racks, ducting, and plant frames are coated to their service exposure — lining-grade resistance for chemical and water vessels, and thermal-cycling and condensation tolerance for pipework.
Floor & High-Traffic Systems
Factory floors and high-traffic surfaces receive abrasion-resistant systems where the working environment demands a tougher film than a structural coat.
Applications Across Ghana & Togo
- Structural steel frames, portal frames, and roof steelwork in factory and warehouse environments across Spintex and the Tema industrial area
- Process and storage tanks, including chemical and water-service vessels requiring lining-grade resistance
- Pipework, ducting, and process pipe racks exposed to thermal cycling and condensation
- Coastal and port-adjacent assets at Tema and Takoradi under elevated saline (C5-M) corrosivity
- Industrial and warehousing steelwork in Lomé (Adidogomé, Agoè) served via our Togo line
How We Deliver an Industrial Coating System
- Corrosivity assessment — the ISO 12944 category (to C5-M marine at the coast) and durability range are set first.
- Surface preparation — steel abrasive-blast cleaned and graded to ISO 8501-1, commonly Sa 2.5, profile confirmed before priming.
- Multi-coat system build — zinc-rich epoxy primer, epoxy MIO midcoat, polyurethane topcoat as the exposure requires.
- Verification & handover — dry-film thickness verified to ISO 2808, adhesion to ASTM D3359, written specification handed over.
Comparing Industrial Coating Systems
| System | Corrosivity (ISO 12944) | Best for | Where in Ghana |
|---|---|---|---|
| 3-coat zinc-rich epoxy → epoxy-MIO → PU | C5 to C5-M | Coastal and port-adjacent steel | Tema, Takoradi |
| Epoxy / epoxy-MIO build | C3 to C4 | Inland factory and warehouse steel | Spintex, inland estates |
| Lining-grade epoxy | Immersion / chemical | Tanks and water-service vessels | Plant sites |
| Abrasion-resistant floor system | High-traffic | Factory floors and access ways | Warehouses, plant |
What Affects the Cost in Accra
- The ISO 12944 corrosivity category and required durability range (C5-M marine work carries a heavier system)
- The condition of the existing steel and whether failed coatings must be removed first
- The surface-preparation grade specified (Sa 2.5 near-white blast versus a lower grade)
- The number of coats and the system selected for the exposure
- Access, plant-shutdown windows, and whether work is on a live or down site
Every quote follows a survey of the asset and its environment — no fixed price is given before the steel is assessed.

Frequently Asked Questions
What is ISO 12944 and why does it matter for steel in Tema? ISO 12944 classifies atmospheric corrosivity from C1 (inland, dry) through C5 to CX (extreme). Coastal and port environments like Tema and Takoradi carry high airborne salt and humidity, which puts them at C5-M (marine) — the most aggressive practical category. Specifying a system to that measured category, rather than a generic inland one, is what keeps a steel asset protected for its intended service life.
How do you prepare steel before coating? Surface preparation is the single biggest determinant of coating life. We abrasive-blast clean steel and grade it to ISO 8501-1, commonly to Sa 2.5 (near-white metal) where the specification requires it, and confirm the surface profile before any primer is applied. A coating laid over poorly prepared steel fails early regardless of the product.
What coating system do you use for marine corrosion at the coast? For C5-M marine exposure at Tema and Takoradi we typically specify a three-coat system: a zinc-rich epoxy primer for sacrificial cathodic protection, an epoxy micaceous-iron-oxide midcoat for barrier strength, and a polyurethane topcoat for UV stability and finish. Each coat is verified to ISO 2808 for dry-film thickness and adhesion to ASTM D3359.
How much does an industrial coating system cost in Accra? It is quoted only after a survey, because cost depends on the corrosivity category, the steel condition, the preparation grade, and the system specified — there is no fixed per-square-metre price. We measure and assess the asset before any figure is given.
