Our FRP Acid and Chemical Storage Tanks are engineered to safely store aggressive chemicals, acids, alkalis, and corrosive process liquids used across various industrial operations. Manufactured using high-performance fiberglass reinforced plastic (FRP) with corrosion-resistant resin systems such as vinyl ester, polyester, or epoxy, these tanks provide exceptional resistance to chemical attack, environmental degradation, and structural stress.

Designed for long service life and safe chemical handling, FRP tanks are widely used in chemical processing plants, pharmaceutical facilities, fertilizer manufacturing units, water and wastewater treatment plants, petrochemical industries, and metal processing facilities, where chemical compatibility, reliability, and operational safety are critical.

Available in vertical or horizontal configurations, the tanks can be manufactured in a wide range of capacities, diameters, and nozzle arrangements to suit specific plant layouts and process requirements. Custom features such as level indicators, manholes, ladders, platforms, agitator mounts, and specialized linings can also be incorporated.

Compared to traditional steel or concrete tanks, FRP tanks offer lightweight construction, easier installation, minimal maintenance, and superior corrosion resistance, making them a highly cost-effective and durable storage solution for demanding industrial environments.

Key Benefits:

  • Excellent corrosion resistance against acids, alkalis, salts, and aggressive chemicals
  • Long service life in highly corrosive industrial environments
  • Lightweight structure allowing easy transportation and installation
  • High strength-to-weight ratio with strong structural integrity
  • Low maintenance requirements compared to steel tanks
  • Leak-proof and seamless construction reducing risk of contamination or chemical leakage
  • Chemical compatibility customization using suitable resin systems and liners
  • UV and weather resistant for outdoor installations
  • Cost-effective lifecycle performance due to lower maintenance and replacement costs
