FRP tanks combine a corrosion-resistant resin matrix with glass-fiber reinforcement. They are commonly used for acids, alkalis, brine, wastewater, water-treatment chemicals and other compatible industrial media. Steel tanks provide high stiffness, mature fabrication systems and better suitability for certain high-temperature, high-pressure or fire-sensitive applications.
Both materials can be used for water, chemicals and industrial process liquids. Selection should consider chemical compatibility, concentration, temperature, pressure, vacuum, impact, fire requirements, inspection access and lifecycle maintenance. Where corrosion is the main concern, a properly designed FRP tank can reduce reliance on coatings, corrosion allowances and repeated repainting, often making it the more practical long-term solution.
