Specialists in industrial coating solutions

Storage Tank Coating Solutions

Storage tanks are critical assets across industries including oil and gas, mining, petrochemical, water treatment, manufacturing, agriculture, food processing, and chemical processing. Whether used to store fuel, water, chemicals, oils, process liquids, or industrial waste, storage tanks must withstand constant exposure to moisture, chemicals, corrosion, temperature fluctuations, and harsh environmental conditions. Without effective protection, corrosion and surface deterioration can compromise structural integrity, contaminate stored products, and result in costly repairs or operational downtime. High-performance protective coating systems are essential for extending the lifespan of storage tanks while ensuring safe and reliable operation.

At Alka Coatings, we provide specialised coating solutions for above-ground and below-ground storage tanks, delivering advanced protective systems that safeguard steel and concrete assets against corrosion, chemical attack, abrasion, and weathering. Our premium epoxy, polyurethane, zinc-rich, and chemical-resistant coatings are engineered to perform in Australia’s toughest industrial environments.

Corrosion Protection for Steel Tanks

Steel storage tanks are continually exposed to moisture, humidity, rainfall, industrial pollutants, coastal salt spray, and changing temperatures that accelerate corrosion. External corrosion can weaken tank walls and supporting structures, while internal corrosion may occur due to the stored product or condensation.

Alka Coatings applies multi-layer protective coating systems that include zinc-rich primers, high-build epoxy intermediate coats, and UV-resistant polyurethane topcoats. These systems provide long-lasting corrosion protection by creating a durable barrier between the steel surface and aggressive environmental conditions, significantly extending the service life of storage tanks.

Internal Tank Linings

The internal surfaces of storage tanks often come into direct contact with fuels, oils, chemicals, potable water, wastewater, solvents, acids, alkalis, and other process liquids. Standard coatings may deteriorate quickly when exposed to these substances, increasing the risk of contamination and corrosion.

Our specialised epoxy lining systems are designed to provide exceptional chemical resistance and long-term durability. Tailored to suit the specific contents of each tank, these high-performance linings help preserve product quality, protect the tank substrate, and reduce ongoing maintenance requirements.

Protection Against Chemicals and Environmental Exposure

Storage tanks located in industrial facilities, refineries, chemical plants, mining operations, and coastal environments require coatings that can withstand aggressive chemicals, UV radiation, heavy rainfall, humidity, and temperature extremes.

Our advanced coating systems resist weathering, fading, chalking, and chemical attack while maintaining excellent adhesion and protective performance. This ensures reliable asset protection even in Australia’s harshest operating conditions.

Secondary Containment and Supporting Infrastructure

Storage tank installations often include bund walls, pipework, loading areas, pump stations, structural steel, valves, platforms, and access walkways. These supporting assets are equally vulnerable to corrosion, chemical exposure, and mechanical wear.

Alka Coatings provides chemical-resistant coatings for secondary containment systems, protecting concrete and steel structures from spills, leaks, and environmental contamination. We also apply corrosion-resistant coatings to structural steel, pipelines, and associated infrastructure to provide complete asset protection throughout the storage facility.

Surface Preparation and Professional Application

The long-term performance of any storage tank coating system depends on thorough surface preparation. Steel surfaces are abrasive blasted to remove rust, mill scale, old coatings, and contaminants before protective primers and topcoats are applied. Concrete tanks and containment structures are mechanically prepared through grinding or abrasive blasting to achieve optimal coating adhesion.

At Alka Coatings, our experienced applicators follow strict quality control procedures and industry best practices to ensure every coating system delivers maximum durability and long-term performance.
