Can fiberglass repairs be made to steel?
Chemical Companies can choose to use composite material for the repairs because it offers many advantages over traditional steel repair methods, but please be aware, a pull test will ultimately determine if an FRP repair is the best choice. Nevertheless, FRP repairs (i.e. composite repairs) are more beneficial for a few reasons.

First, the composite material will not rust like steel, which would allow the tanks to remain operational for longer periods of time. Second, the composite material would offer superior resistance to chemicals and UV rays than steel. Third, the composite material could be easily cut and shaped to fit the contours of the tank. Finally, the composite material could withstand high temperatures without warping or melting.

When it comes to FRP Tanks, there are a few things you'll want to consider. 

  1. NEVER roll or slide a tank. Lift the tank using a crane or another approved method.

  2. Operators of hoist equipment should follow proper rigging procedures at all times. NEVER allow the tank to swing out of control.

  3. Do not drop or allow hard impact from tools, spreader bars, etc.

  4. Avoid the use of equipment inside the tank that could scratch or damage the inner corrosion barrier

  5. NEVER use cables or chains around the tank.

  6. NEVER lift the tank by using fittings. Use designated lifting lugs.

  7. If tanks are being stored prior to installation, be sure to lay them on a padded surface and tie them down securely.


The most common cause of failure of a fiberglass tank is due to internal corrosion. Corrosion occurs when water comes into contact with the metal surface of the tank. This causes the metal to oxidize and form rust which eventually dissolves away leaving bare metal exposed.

Corrosion-resistant materials are used to protect steel tanks from corrosion. The material must be able to withstand the chemical environment inside the tank without corroding itself. This is done through the use of a protective coating on the outside of the tank. These coatings are made up of layers of different materials. The first layer is usually a thin film of epoxy resin which protects the steel from further corrosion. Next comes a layer of polyester resin which acts as a sacrificial agent and prevents any further corrosion from occurring. Finally, there is a layer of glass fibers that provide additional protection against corrosion.

Fiberglass tanks are made of glass-reinforced polyester resin. They are usually made of two layers of material, which are bonded together. The first layer is called the "skin" and the second layer is called the "bulk." The skin is where most of the weight of the tank comes from. It is very strong and rigid. The bulk is much softer than the skin and allows the tank to flex and bend. This flexibility makes fiberglass tanks ideal for storing chemicals like gasoline and oil.


High-Performance Coatings are used to protect surfaces against corrosion, wear, and abrasion. They are applied over existing paints and sealers to provide additional protection. The most common types include epoxy, polyurethane, acrylic, and alkyd resins.


Plastic welding is the joining of two pieces of plastic using heat and pressure. It is used to join together parts made of dissimilar plastics, such as polycarbonate and ABS. This method is commonly used on car bumpers, where the bumper is attached to the frame of the vehicle.

We make plastic welding / thermoplastic welding repairs on tanks and piping.
