If you’re scouting for Other Products in fiberglass that refuse to be generic, you’re in the right place. Jrain’s team in Hebei, China has been building odd-shaped, pressure-rated, color-matched parts for years—think medical bed components, pipe stands, moisture collectors, playing boxes, planters, desalination parts, drums, and the one-off ideas customers sketch on napkins. To be honest, that last group is my favorite.
Three currents are reshaping custom FRP: corrosion-resistant infrastructure (water and wastewater), non-conductive fixtures for healthcare and power facilities, and lightweight urban installations (rooftop planters, acoustic enclosures). Sustainability is part of it: a lighter composite part can cut transport and installation emissions, and, surprisingly, it often survives harsher environments than coated steel.
| Parameter | Typical Range (≈, real-world use may vary) | Notes / Standards |
|---|---|---|
| Resin system | Isophthalic polyester / vinyl ester | Corrosion/temperature tuned |
| Reinforcement | E-glass mat, roving, fabric | Orientation per load case |
| Tensile strength | ≈ 200–350 MPa | ASTM D638 |
| Flexural strength / modulus | ≈ 300–500 MPa / 9–15 GPa | ASTM D790 |
| Density | ≈ 1.6–1.9 g/cm³ | ASTM D792 |
| Barcol hardness | ≈ 40–50 | ASTM D2583 |
| Temp range | ≈ −40 to +110 °C (higher with VE) | Application-specific |
| Flame/smoke options | UL 94 V-0 / ASTM E84 packages | On request |
Materials: corrosion-grade resins, UV-stable gelcoats, glass fabrics, cores (PVC, PET, foam) if needed.
Methods: hand lay-up for complex shapes, RTM for smoother Class-A surfaces, filament winding for cylindrical parts, pultrusion for linear supports.
Testing & standards: tensile (ASTM D638), flexural (D790), water absorption (D570), Barcol (D2583), flame/smoke (UL 94, ASTM E84). Piping/pressure-related builds can align with ISO 14692 or ASME RTP-1 depending on scope.
Service life: around 15–25 years in outdoor industrial settings; longer in mild exposure with proper coatings. Customers, in fact, often report “install and forget.”
| Vendor | Customization depth | MOQ | Lead time | Certs / Standards |
|---|---|---|---|---|
| Jrain (Other Products) | High (freeform, pressure, color, texture) | Small-batch friendly | ≈ 2–5 weeks | ASTM-tested; ISO 14692/ASME RTP-1/NSF 61 on request |
| Vendor A (generic) | Medium (catalog + tweaks) | Moderate | ≈ 4–8 weeks | Varies; limited custom testing |
| Vendor B (volume) | Low–Medium | High | ≈ 6–10 weeks | Catalog standards |
Desalination plant upgrade: FRP pipe stands replaced galvanized steel; reported 65% weight reduction and no rust after 24 months coastal exposure (ASTM B117 500h lab validation, then field check). A hospital’s MRI wing used composite bed frames and carts—non-magnetic, easy to wipe down, zero conductivity surprises. A developer swapped concrete planters for FRP on a rooftop: load cut by ≈ 60%, installation in one afternoon. I guess the crane operator was the happiest.
Origin: No. 1289, Yingbin South Street, Jizhou District, Hengshui, Hebei, China.
Many customers say communication is fast and the samples arrive “as drawn,” which, frankly, is what counts in custom work.
