FRP Ducting & Ventilation Systems
Hand lay-up (and matched mold) fiberglass ductwork for corrosive fume exhaust — acid mist, alkali vapor, chemical plant ventilation. Round and rectangular ducts, bends, dampers, hoods and junctions, made to your ducting drawing.
Key specifications (industry-typical; subject to our confirmed products)
| Duct diameter | Ø 100 mm – Ø 1500 mm |
| Wall thickness | 4 mm – 10 mm (by static pressure / media) |
| Resin system | UP for general exhaust; VE for acid fumes |
| Joint | Flanged / socket |
| Operating temp | −20 °C – +120 °C typical |
Description
Ductwork is almost always non-standard — odd sizes, site offsets, unusual flange arrangements. Hand lay-up needs only cheap wooden/GRP patterns instead of expensive steel tooling, which is why buyers come to a hand lay-up shop.

A: Yes — send the CAD sketch plus working environment (chemicals, temperature); we advise resin system and laminate schedule.
Q: UP or VE resin for fume exhaust?
A: UP for general / corrosion-light exhaust; vinyl ester for strong acid or alkali fumes.
