Fiberglass-reinforced plastic (FRP) is a composite material made by combining glass fiber reinforcements with a polymer resin matrix. The glass fibers add tensile strength and rigidity, while the resin bonds everything together and creates a protective barrier against environmental exposure.
Unlike steel or iron, FRP doesn't participate in electrochemical reactions. When traditional materials come into contact with moisture, oxygen, or industrial chemicals, electrons move between anodic and cathodic sites on the surface—creating oxidation that weakens the structure over time.
FRP sidesteps this problem entirely. The glass fibers and polymer resins are chemically inert to the environmental factors that attack traditional materials. No electrochemical cell forms, so the material maintains its structural integrity year after year.
Steel gives you strength but also brings weight and conductivity issues. Protective coatings help, but they scratch, wear, and require reapplication. Once the barrier fails, degradation starts immediately—and accelerates in the presence of salts, acids, and industrial chemicals.
Wood degrades through moisture absorption, UV exposure, and biological attack. Chemical treatments can extend service life, but they introduce environmental concerns and still require periodic maintenance.
FRP eliminates these trade-offs. It won't absorb water, doesn't react with most chemicals, and maintains dimensional stability across temperature swings that would cause traditional materials to expand, contract, and loosen joints.
Standard profiles get close to what you need—but not close enough. You might find a shape that fits, but the resin system isn't rated for your chemical exposure. Or the fiber architecture doesn't deliver the load capacity your application requires.
Custom pultruded FRP profiles let you engineer the solution from the ground up. You can adjust the resin system—polyester, vinyl ester, or epoxy—to match specific chemical exposures. You can modify the fiber architecture to optimize for flexural strength, impact resistance, or stiffness.
At Tencom, custom doesn't mean "we'll run whatever die you send us." It means sitting down with your team to look at the whole picture: mechanical loads, environmental exposure, installation requirements, and long-term performance targets.
Choosing the right resin is the most critical factor in long-term FRP performance. Different resin systems offer different levels of resistance to specific chemicals and temperature ranges.
Vinyl ester resins offer broad resistance to acids, alkalis, and organic solvents. They're commonly specified for chemical processing equipment, tanks, and piping exposed to aggressive media like hydrochloric acid, sodium hydroxide, and chlorine compounds.
Epoxy resins offer superior mechanical properties and perform well in applications requiring elevated-temperature resistance. Polyester resins offer cost-effective protection for less demanding environments while still outperforming traditional materials by a wide margin.
Industrial buyers and purchasing managers across multiple sectors have shifted to FRP for applications where material degradation creates ongoing problems:
In each case, the goal is the same: reduce maintenance cycles, extend service life, and lower total cost of ownership.
The pultrusion process produces FRP profiles with constant cross-sections in a single, automated manufacturing step. Glass fiber reinforcements—including rovings and woven mats—are pulled through a resin bath, then through a heated steel die where the composite cures into its final shape.
This manufacturing method offers precise control over fiber-to-resin ratios and dimensional tolerances. Tencom custom fiberglass pultrusion produces profiles with tolerances as tight as 0.005 inches—delivering components ready for precision applications.
The process also allows UV inhibitors, fire retardants, and pigments to be incorporated during production. You get a finished component with built-in protection rather than relying on surface coatings that can wear or fail.
The upfront material cost of FRP often exceeds that of steel or wood. But that comparison misses the full picture. Consider what traditional materials cost over a 10- to 15-year lifecycle: inspection schedules, protective coatings, replacement of degraded components, and unplanned downtime when failures occur.
FRP profiles require minimal maintenance. They don't need painting or galvanizing. They resist UV degradation when properly formulated. And because they're significantly lighter than steel—up to 70% lighter in some applications—you save on transportation and installation labor as well.
When you work backward from the total cost of ownership rather than the purchase price alone, FRP frequently delivers better value. That's why purchasing managers focused on lifecycle costs are increasingly specifying FRP for demanding applications.
Many FRP suppliers focus on high-volume production runs, leaving smaller projects without access to custom-engineered solutions. That's where working with a manufacturer focused on serving smaller customers makes a difference.
Tencom offers lower order minimums for custom pultruded profiles, making it practical to specify exactly the right material for your application—even on smaller projects. You get the same engineering collaboration, resin selection expertise, and quality control that large-volume customers receive.
This approach means you don't have to compromise on material performance just because your order quantity doesn't meet another supplier's minimum threshold.
If you've been dealing with recurring material degradation, escalating maintenance costs, or premature component failures in harsh environments, it's worth evaluating what custom pultruded FRP profiles could deliver.
Tencom engineers work with your team to look at the whole picture—mechanical loads, chemical exposure, installation requirements, and long-term performance targets. Sometimes that means a slight modification to an existing profile. Other times it means designing something new from the ground up.

Steel and similar materials undergo electrochemical reactions when exposed to moisture and oxygen. FRP components are chemically inert to these factors.
No electrochemical cell forms, so the material maintains structural integrity even in environments that would rapidly degrade traditional materials. Tencom custom FRP profiles are engineered with the right resin system to handle your specific exposure conditions.
Well-engineered FRP profiles can deliver service lives of 20 years or more in demanding industrial environments—often outlasting steel equivalents by a factor of three to four.
Tencom designs each profile with specific environmental exposure and mechanical requirements in mind to maximize longevity and minimize lifecycle costs.
Yes—with the right resin system. Vinyl ester resins offer broad resistance to acids, alkalis, and organic solvents. Epoxy resins work well in high-temperature applications.
Tencom engineers help you select the appropriate resin system based on your specific chemical exposure, temperature range, and mechanical requirements.
Absolutely. Tencom offers lower order minimums than many FRP suppliers, making custom-engineered profiles accessible for projects of all sizes.
You get the same engineering collaboration and quality control whether you're ordering a small batch or a large production run.
Tencom focuses on serving smaller customers with custom research and testing capabilities. Our engineers sit down with your team to look at the whole picture before recommending a solution.
With nearly three decades of focused pultrusion experience, Tencom delivers profiles engineered for your exact requirements—not generic shapes that get you "close enough."
