FRP Bangalore A division of RJ Interiors & Constructions

Industrial FRP products: tanks, linings and gutters

Steel rusts and concrete leaks where water, effluent and chemicals sit. We make FRP tanks and MS FRP tanks to size, line existing tanks and gutters with FRP, and mould custom parts to your drawing, with the resin chosen for the job.

Matching the resin to the duty

FRP's resistance comes from its resin. This is the general guide; we confirm the choice for your contents and temperature before we quote.

General guide to FRP resin choice by duty
What it holds or faces Usual choice
Water, rainwater and mild effluent Isophthalic polyester resin
Stronger acids and alkalis Vinyl ester resin, chosen for the chemical
Higher temperatures A resin rated for the working temperature
Exposed to sun outdoors UV-resistant gelcoat or paint on the outside

FRP lining for what you already have

Replacing a corroded tank or a leaking concrete gutter is slow and disruptive. Lining it often isn't.

An FRP lining is laminated in place over the cleaned and prepared surface: inside mild steel tanks, concrete sumps and effluent tanks, and along concrete gutters and drains. It cures into one continuous layer with no joints.

We inspect first, because a lining needs sound steel or concrete behind it. Then we tell you what preparation is needed and how long the tank or gutter will be out of use. See FRP tanks and MS FRP tanks, FRP waterproofing and FRP gutters.

Questions about industrial FRP

Can you line our existing tank, sump or drain?

Usually, if the steel or concrete is sound. The surface is cleaned and prepared, and an FRP lining is laminated in place. We'll inspect it first and tell you if repairs are needed.

What do you need to quote for a chemical tank?

The chemical and its concentration, the working temperature, the capacity, the space available, and where the inlets, outlets and vents go.

Do you supply industrial FRP outside Karnataka?

Yes. We make everything in Bangalore and supply across India. Tanks are delivered ready to set in place.

Can you make covers, hoods or other parts to our drawing?

Yes. Send the drawing with the material duty, and we'll make the mould and the part.
