Our Approach to Quality
Quality in FRP manufacturing isn't about a final inspection stamp. It's a series of checks that start with raw material receipts and continue through to packing. Our approach is built around consistency — running the same tests, to the same methods, on every batch — so that the product our customer receives matches the product they specified. We don't claim perfection on every panel ever produced; we claim a systematic way of catching deviations before product leaves the facility.
The framework we follow is aligned with ISO 9001 principles. Documented procedures define how we handle incoming materials, in-process monitoring, finished product testing, and what happens when something doesn't meet the mark. Those procedures are reviewed and updated as equipment changes or new product types enter production.
What We Test, and When
Testing is performed on samples drawn from each production batch — grating panels, structural profiles, and rebar alike. The specific tests depend on the product type and the specification it's being manufactured against.
- Tensile properties — a specimen is pulled to failure on a universal testing machine, giving us ultimate tensile strength and modulus of elasticity in tension. This applies primarily to structural profiles and rebar products.
- Flexural properties — tested under three-point loading. Flexural strength and modulus are the primary mechanical specifications for grating panels and most structural profiles.
- Barcol hardness — a surface hardness measurement used as an indicator of cure completeness. A reading below the expected range for a given resin system prompts a closer look at the cure cycle for that batch.
- Reinforcement tensile testing — for GFRP and BFRP rebar, the tensile strength and modulus of the rebar core are tested on samples taken from each production run.
- Resin content verification — using burn-off testing. A weighed specimen goes into a furnace at controlled temperature until the resin is fully combusted. The remaining glass mass tells us the resin-to-glass ratio for that batch. If the ratio falls outside the target window for the product type, the batch is held for investigation.
- Dimensional checks — grating panels are measured for thickness, mesh opening, and overall length and width. Structural profiles are checked for cross-sectional dimensions, straightness, and cut length. Custom fabrications get a separate dimensional inspection against the project fabrication drawings.
All mechanical testing is conducted in our on-site laboratory, located within the same facility as our pultrusion and molding operations. This keeps the feedback loop between testing and production short — if a batch result raises a question, the production team can investigate without delay.
When a Batch Falls Outside Spec
It happens. A resin content comes back outside the target range. A Barcol reading doesn't align with the expected cure window. A dimensional check picks up a panel thickness variation beyond what the customer drawing allows. When it does, the batch is quarantined pending investigation. The goal isn't to assign blame — it's to understand whether the root cause is a one-off, like a thermocouple fault or a resin batch variation, or something that needs a procedure change. The corrective action gets documented, and the record stays with the batch file. If a customer ever needs to trace the history of a specific product, the batch number leads back to every test result and any investigation notes associated with that production run.
Traceability
Every finished product leaving the facility carries a batch identifier. That identifier links back to the production date, the resin batch numbers used, the shift that ran it, the mold or die number, and the mechanical test results from that batch's samples. Test records and batch files are retained for the expected design life of the products they document. If a question comes up years after installation — about a particular resin formulation used, or the test results for a specific grating panel — we can retrieve that information as long as we have the batch number.
Documentation We Provide
Standard documentation accompanying each order typically includes a batch-specific mechanical test report, a certificate of conformance confirming the product aligns with the specified standard, and material safety data sheets for the cured FRP product. Where project specifications call for additional documentation — third-party inspection, raw material certifications, or specific regulatory paperwork — we arrange that at the order stage and include it with the shipment.
The intent behind our documentation is straightforward: the customer should have enough information to verify that what they received matches what was specified. If further documentation is required after delivery, we can retrieve it from the batch archive.
