In this guide, we’ll cover the advantages of FRP pipes and fittings, where to find fiberglass pipe for sale, and how to choose the right solution for your specific application.
Fiberglass pipe is made from glass fibers embedded in a resin matrix, typically polyester, vinyl ester, or epoxy. This composite construction results in a pipe that is:
Corrosion-resistant
Structurally strong
Lightweight
Thermally stable
It’s widely used in industries where metal pipes would quickly degrade due to chemicals, saltwater, or environmental exposure.
FRP systems are modular and come with a variety of fittings and formats to suit different layouts. Key components include:
Straight Pipes: Standard lengths for transporting liquids or gases.
Elbows and Bends: Allow directional changes without stress on the system.
Tees and Crosses: For branching or joining multiple pipelines.
Reducers: Connect pipes of different diameters.
Flanges: For secure connections to tanks, pumps, or other systems.
Most FRP pipes and fittings are available in diameters ranging from 1 inch to over 60 inches, and pressure ratings from 50 to 300+ PSI depending on wall thickness and resin type.
Unlike steel, fiberglass does not rust or corrode—making it ideal for seawater, brine, acids, and aggressive chemicals.
FRP is about 1/5 the weight of steel, making it easier and cheaper to transport and install.
Once installed, fiberglass pipe systems require minimal upkeep. No painting, no rust-proofing, and fewer replacements.
Fiberglass has low thermal conductivity, reducing energy loss in hot or cold fluid applications.
Depending on the resin and application, fiberglass pipes can last 30–50 years or more.
Need something unique? FRP pipes and fittings can be manufactured to exact specifications—including diameter, pressure, temperature, and chemical resistance.
FRP pipe is trusted in harsh, high-performance environments like:
Chemical Processing – Sulfuric acid, caustic soda, chlorine, etc.
Desalination Plants – Saltwater intake and brine discharge lines.
Power Plants – Cooling water systems and flue gas treatment.
Municipal Water & Wastewater – Sewer, stormwater, and potable water lines.
Oil & Gas – Onshore and offshore piping exposed to corrosive fluids and environments.
Mining – Slurry transport, acidic drainage, and effluent lines.
When shopping for fiberglass pipe for sale, don’t just look at price—evaluate the full value. Here's what matters:
Choose based on the fluid being handled. Vinyl ester offers superior chemical resistance, while polyester is more economical for less aggressive environments.
Ensure the pipe wall thickness and construction meet your required PSI. Underrated pipes can lead to failure.
Standard FRP can handle up to ~200°F (93°C), but high-temp resins can go higher.
Look for ASTM D, ISO , or AWWA C950 compliance—especially for municipal and industrial use.
Reputable sellers provide technical drawings, installation guides, and field support if needed.
Ask about the warranty and request QA/QC reports for high-stakes applications.
The cost of fiberglass pipe depends on several key variables:
As a rough guide, expect pricing from $15–$100 per linear foot, depending on the specs.

Yes. They can be manufactured to handle pressures over 300 PSI, depending on wall thickness and construction.
Yes, if they are made with NSF-certified resins and coatings.
Absolutely. FRP pipes are often buried and can be designed for soil loads, ground movement, and even seismic activity.
Installation is straightforward and does not require welding—cutting and bonding are done with simple tools and adhesives. Many suppliers also offer joint kits or flanged systems.
A: Typically, FRP stands for fiber reinforced plastic and the FRP beams are normally referred to as wide flange beams, channels, and H beams. Those typical applications are for walkways, catwalks, and anywhere where corrosion resistance is needed for an application vs. traditional materials.
FRP has gone from a relatively unknown product a few decades ago, to being a formidable contender to traditional building materials. Wood, aluminum, and steel simply can’t match the strength, durability, and long-term value of fiber reinforced plastic. FRP beams are just one major example of how it is changing the industry
More recently, over the last five years, economic trade policies such as the steel tariffs and inflation have impacted construction. The price of steel, aluminum, and lumber have all seen an astronomical rise in cost.
FRP has not gotten through the pandemic and supply chain issues unscathed either as prices have increased with inflation. However, where FRP holds an advantage is that the ownership cost of fiber reinforced plastic is still far lower than steel or wood.
Steel corrodes with simple exposure to moisture and the rate of degradation spikes when used in a corrosive environment. Wood is not reliable for the long term as it rots with moisture, warps with heat, and is susceptible to termites and fire.
That leaves FRP in a very comfortable position—even in this struggling pandemic plagued economy. FRP is setting the standards for safety in all industries with all of its outstanding features. The lion’s share of FRP manufactured for all industries is comprised mainly of pultruded grating and FRP beams.
So what exactly is this miracle material and why is its use spreading like wildfire across various sectors? The quick answer is simple—it’s simply better all around.
To understand why the use of FRP beams has exploded over the last decade you have to understand what FRP is. FRP as mentioned is short for fiber reinforced plastic—but that doesn’t answer what it’s made of.
FRP is a composite made up of a thermosetting resin and fiberglass, which are very thin fibers of glass, hence the name. These glass fibers and the various resins it is combined with are what make up the base ingredients of FRP products.
The resins are what contribute to the various environmental and chemical resistance qualities. They also act as the binder for the glass fibers within the structural layer. DEFI products generally are comprised of three layers also referred to as laminates.
As you can see, the biggest selling point in FRP lies in the structural strength and durability it exhibits in any application.
FRP beams exhibit all of the traits that make FRP so durable. Corrosion resistance, lightweight, impact resistance, fire resistance, and more. The best part that’s often overlooked, is the flexibility of FRP beams—they can be customized to the needs of any application.
The FRP beams we manufacture are mainly used to support structures used within large industrial operations. Environments such as chemical plants, automobile manufacturers, meat processing plants, and construction sites.
These beams are as strong as steel while weighing in at only a fraction of their steel counterpart. This means savings on so many angles. Installation is completed with simple tools and there’s no heavy machinery needed to lift FRP beams either. So, right out of the gate, FRP is saving businesses money and time, which we know time is money too. But that’s just scratching the surface of the benefits of using FRP in structural applications.
A business at its core must remain profitable to survive. Aside from smart business decisions and good marketing, there must be efficient manufacturing. There are several areas where you can boost efficiency in manufacturing— workflow processes, procurement of resources, and infrastructure. Those are three of the biggest shortcomings of businesses that fail.
All go hand in hand, but the infrastructure is usually what can eat up operating budgets if not properly handled. Centering your infrastructure around FRP whenever possible is a crucial key to a lean approach. There’s several key benefits that FRP beams and other FRP products give a business. Here’s just a few of those benefits that are causing FRP use to skyrocket over the last five years.
The biggest limitation business are faced with when using steel, is that structure design is limited due to the weight. Compromises have to be made as complex designs use a lot of steel and eventually the design costs more in installation.
Because steel is so heavy, a large design often requires pouring thick concrete foundations for reinforcement. That’s an expensive task in and of itself, in addition to the structure construction cost.
FRP is so lightweight that it makes design potential free from constraints. You can build out your structure exactly as you envision it. From a walkway to a ladder and cage system, or trench grating—there’s no limits.
One factor many overlook when using steel is the cost to transport the steel components to your project site. It gets extremely expensive very fast, therefore, once again—you have to limit your design. Since fiberglass is so light the cargo is a fraction of what steel costs. Additionally, it’s easy to carry it around your construction site. No heavy flatbed trucks needed, no cranes either.
This is probably the most unique feature of FRP, specifically FRP beams. As light as it is, one would think that it’s not as tough as steel. Ironically it’s more durable than steel as it outclasses steel handily in terms of durability, mechanical strength, and resistance to extreme conditions.
FRP is not affected by chemicals, saltwater, acid, and other corrosives. Metal would be shot after a mere week of exposure. Wood would warp and rot, steel would corrode, but FRP is unfazed. This is why it’s heavily used for outdoor structures in chemical plants, refineries, marine applications, and other similar environments.
Often buyers are so focused on the big money-saving benefits they forget that there’s some unsung benefits as well. These may seem minor, but in the big picture, they are huge advantages.
