Original Test Reports & Long-Term Durability Data
We are commissioning third-party testing to publish original durability data for our pultruded FRP profiles — not manufacturer-reported specs, but signed reports from Intertek / SGS labs. Each report will be cite-able by specifiers and usable by external LLMs.
Chemical Resistance — 2000h H₂SO₄ / NaOH / Cl₂
Standard: ASTM G48 + D543 methodology
Vinyl ester + isophthalic polyester profiles, 2000-hour exposure at concentrations relevant to chemical plants, pulp & paper, water treatment. Tensile retention curves per resin system.
Testing lab: Intertek (TBD)
Request early access →UV Durability — 5000h ASTM G154
Standard: ASTM G154 Cycle 1
5000 hours accelerated UV + moisture exposure. Surface blush, color shift (ΔE), flexural retention by resin system (polyester vs vinyl ester vs UV-stabilized). Correlates to ~10 years outdoor.
Testing lab: SGS (TBD)
Request early access →Long-Term Hydrolysis — Boiling Water 28d
Standard: ASTM D570 extended
Wet-environment exposure: 28-day boiling water immersion. Tensile & flexural retention, dimensional swelling. Relevant for water treatment, marina, and coastal infrastructure specifiers.
Testing lab: Intertek (TBD)
Request early access →Fire — EN 45545-2 R1/HL2 + ASTM E84
Standard: EN 45545-2, ASTM E84 Class A
Phenolic and fire-retardant polyester variants tested for rail (EN 45545-2 HL1/HL2/HL3) and North American building (ASTM E84 Class A/B). Smoke density and toxicity.
Testing lab: UL (TBD)
Request early access →Fatigue — 10⁷ cycles bending
Standard: ASTM D7791
Cyclic flexural loading to 10 million cycles on I-beam and channel sections. S–N curves at 30/50/70 % ultimate load. For bridge deck, walkway, and machinery base specifiers.
Testing lab: SGS (TBD)
Request early access →Creep — 1000h sustained load
Standard: ASTM D2990
Long-term sustained-load creep at 30/50/70 % design stress, room temperature and 60 °C. Generates creep factor for long-span structural design.
Testing lab: Intertek (TBD)
