Fiberglass Rod Reinforcement in Containment Systems

Fiberglass rod reinforcement has emerged as a popular option for physical support in containment systems in a variety of industries. This technology has been developed to enhance the structural integrity of containment systems by reducing the likelihood of leaks, spills, and other types of damage. Fiberglass rod reinforcement has been used in leak and spill containment systems around the US and the world. Goodwinds Composites is equipped to supply fiberglass rods cut to spec for spill berms, bladder storage, and other containment system and tarp manufacturers.

Advantages of Fiberglass Rod Reinforcement in Containment Systems

  1. Strength and Durability

Fiberglass rods are incredibly strong and durable, making them an excellent structural reinforcement for containment systems. The strength of fiberglass rods is derived from the unique composition of the material, which consists of glass fibers that are embedded in a resin matrix, most often polyester. The combination of these materials creates a finished rod that is both strong and flexible, allowing it to withstand significant stresses and strains without breaking.

Additionally, fiberglass rods are resistant to corrosion and chemical attack. This makes them ideal for use in containment systems that store hazardous materials such as chemicals and petroleum products. Unlike metal reinforcements, fiberglass rods do not rust or corrode.

  1. Lightweight

Fiberglass rods are significantly lighter than traditional steel reinforcements, making them easier to transport and install. They do not require heavy lifting equipment during installation, which can save time and money. Additionally, the lightweight nature of fiberglass rods means that they can be easily maneuvered into place during installation.

  1. Easy to Install

Fiberglass rod reinforcement is relatively easy to install in containment systems, saving time and money. Unlike traditional steel reinforcement, fiberglass rods do not require welding and can be easily cut to size using simple hand tools or pre-cut to spec by Goodwinds Composites. Because they do not require welding and are lightweight, anyone can install fiberglass rod reinforcements with minimal training.

  1. Low Maintenance

Fiberglass rod reinforcements are low maintenance. Unlike steel reinforcements or rebar, fiberglass rods do not rust or corrode, which means they do not require regular maintenance to prevent damage. Additionally, fiberglass rods can withstand exposure to a wide range of chemicals without becoming damaged. This can further reduce maintenance costs by reducing the need for inspection and repair of containment system components.

  1. Cost-Effective

Fiberglass rods are cost-effective when compared to traditional steel reinforcement. In addition to upfront savings in the initial cost of structural fiberglass rods, the cost of cutting, installation, and maintenance are much less than metal reinforcement over the life of the containment system.

Disadvantages of Fiberglass Rod Reinforcement in Containment Systems

  1. Limited Temperature Range

Fiberglass rods have a temperature range which can limit their use in certain applications of extreme heat. For example, fiberglass rod reinforcement might not be suitable for applications like industrial furnaces or boilers. At temperatures above 180°F, fiberglass rods can begin to weaken and lose structural integrity. If a containment system is exposed to high temperatures, the fiberglass rod may fail. In such cases, alternative reinforcement such as carbon rod may be recommended.

  1. Limited UV Resistance

Fiberglass rods are not inherently UV resistant, which can limit their uses in outdoor environments. Exposure to UV radiation can cause the fiberglass rods to weaken and lose strength over time. Most containment systems that use fiberglass rod reinforcement limit UV exposure by inserting the fiberglass rods into sleeves in the tarp or berm material.

  1. Difficulty Bonding

Fiberglass rods can be difficult to join, particularly in applications that require complex shapes or angles. Unlike steel reinforcements, fiberglass rods cannot be welded, which means that alternative joining methods such as adhesive bonding or mechanical fastening must be used. The difficulty in joining fiberglass rods can increase installation time and cost – Goodwinds Composites can cut your rods to the perfect length to eliminate the need for joints. We can also help you choose fiberglass connectors and adhesives for your project.

  1. Limited Availability of Large Diameter Rods

Goodwinds Composites carries fiberglass rods in sizes ranging from .062 inches in diameter to .750 inches in diameter. Larger rods are heavy, difficult to ship, and tough to cut to size. For applications that require larger diameter reinforcements, consider a fiberglass tube or carbon tube.


Fiberglass rods are a popular option for reinforcing containment systems, spill berms, and other tarp and fabric installations due to their strength, durability, weight, ease of installation, low maintenance requirements, and cost-effectiveness. When considering fiberglass rod reinforcement in any project, it is important to take into consideration temperature demands, UV exposure, and rod diameter to determine the best reinforcement option. Goodwinds Composites has a wide variety of fiberglass rods available for sale with no minimum order or cutting fee and can custom manufacture large production orders.
