Why Choose FRP Tanks?
FRP tanks offer superior performance and reliability compared to traditional materials
Horizontal Tank
Designed for horizontal installation; ideal where height is limited. Offers low center of gravity, easy transport and skid mounting.
Leg‑Supported Tank
Elevated on FRP legs for clear access below, easy bottom‑nozzle maintenance and reliable gravity discharge.
Vertical Tank
Installed vertically to minimize footprint. Economical for large volumes and simplifies level measurement and maintenance.
Sloped Bottom Tank
Internal sloped floor to the lowest point for gravity drainage, reduced tank heel and improved solids removal.
Insulated Tank
Thermal insulation layer to maintain process temperature. This helps to keep the temperature of the liquid inside the tank constant regardless of the ambient temperature within a range.
Square Tank
Square/rectangular geometry for scrubbers or tight spaces; integrates against walls or frames and maximizes floor area usage.
Skirted Tank
FRP skirt elevates and protects the shell and outlets; enables gravity drain and provides clean, safe access below the tank.
Steel Ring Tank
Steel lifting/anchoring ring with engineered pick points for hoisting, suspension or custom support systems.
