FRP Columns / Towers
FRP (Fiberglass Reinforced Plastic) columns and towers are high-performance structures designed for use in corrosive, high-demand industrial environments. These vertical process vessels are commonly used in pulp & paper, chlor-alkali, mining, chemical processing, and waste treatment operations, where they provide robust resistance to sulfuric acid, chlorine, and other aggressive substances.
Compared to metallic towers made from exotic alloys, FRP columns offer a cost-effective, lightweight, and corrosion-resistant alternative — making them the preferred choice for both greenfield and retrofit installations.
In addition to the tower shell, we provide custom-designed FRP internals, including support grids, distributors, packing supports, and demisters. These components play a critical role in optimizing process efficiency and ensuring reliable operation under varying flow and chemical conditions.
We specialize in manufacturing of high-quality FRP (Fiberglass Reinforced Plastic) storage columns designed for various industries, including chemical processing, chlor-alkali, mining, petrochemicals, pulp and paper, steel, hydrogen and wastewater treatment. Our columns are engineered to provide exceptional strength, corrosion resistance, and longevity, ensuring your storage solutions are both safe and reliable.

Features & Benefits
Corrosion
Resistance
Designed to handle harsh chemicals like sulfuric acid, FRP towers and internals offer exceptional resistance to corrosion and chemical attack. Corrosion resistance can be enhanced by using a fluoropolymer inner liner.
Lightweight & Easy to Install
FRP is significantly lighter than steel (75% lighter) and aluminum (30% lighter), enabling easier transport and installation, reducing costs in handling, fuel consumption, and installation
Low
Maintenance
Smooth internal surfaces, corrosion resistance, and durable construction reduce cleaning and maintenance frequency, minimizing maintenance and reducing costs.
Thermal
Insulation
Composite materials offer excellent insulation, maintaining durability without becoming brittle in cold conditions.
Compliance with Standards
All towers and internals are designed and tested to meet or exceed industry safety and performance standards, ensuring reliable operation.
Custom-Engineered Internals
Each tower can be equipped with tailored internals to ensure effective fluid distribution, phase contact, and mass transfer efficiency.
Frequently Asked Questions (FAQs)
FRP columns or towers are vertical process vessels made from fiberglass-reinforced plastic, ideal for handling corrosive liquids and gases in industrial applications. The resin provides corrosion resistance and the fiber glass provides mechanical strength. FRP or GRP columns are high-quality, durable towers offering exceptional strength and corrosion resistance. They are widely used in industries such as chemical processing, water treatment, mining, and petrochemicals.
Custom-designed internals enhance fluid distribution, increase mass transfer efficiency, and ensure consistent process performance under variable conditions.
FRP tanks are significantly lighter (up to 75% lighter than steel and 30% lighter than aluminum), highly corrosion-resistant, require less maintenance, and offer superior thermal insulation. These features make them a safer and more cost-effective alternative to traditional materials.
We provide a range of tower internals including packing supports, distributors, trays, mist eliminators, and support grids — all built from corrosion-resistant FRP.
FRP columns are used in pulp & paper, chlor-alkali, chemical processing, fertilizers, and effluent treatment plants, among others.
Yes, we manufacture columns in various sizes and shapes. Customization includes pure FRP or dual laminate tanks with thermoplastic liners like PP, HDPE, PVC, CPVC, or fluoropolymer liners like PVDF, PTFE, TFM, ETFE, ECTFE, FEP, and PFA.
