Fibreglass cooling towers & engineered components.
GemRock manufactures fibreglass cooling towers and bespoke GRP components for industry, engineered in-house.
GemRock now leads with fibreglass repair. We still manufacture cooling towers and GRP components.
Tower, tank or bund already in service? Industrial GRP repairFibreglass cooling towers, built to outlast steel.
GRP cooling towers don't corrode, scale or rust the way metal does — so they run longer, quieter and with far less maintenance, even in chemically aggressive environments.
- Corrosion-proof. Fibreglass shells shrug off moisture, salt and chemicals that eat steel.
- Engineered to spec. Counterflow and crossflow configurations, sized to your duty — placeholder.
- Low-maintenance. No repainting or galvanising; decades of service life — placeholder figures.
What we engineer in fibreglass.
Indicative capability areas — placeholder content.
Custom components
Bespoke fibreglass parts engineered to spec, from prototype to production run.
Material engineering
In-house formulation for strength, weight, thermal and chemical resistance.
Demanding environments
Solutions built to perform under load, weather and corrosive conditions.
Where it's used.
Engineered to order, moulded in-house.
Beyond cooling towers, we mould and pultrude fibreglass to your drawings — tanks, enclosures, housings, structural sections and one-off components for chemically aggressive and outdoor environments.
Defence & security work is handled separately — see the Defence division.
Tower, tank or bund already in service?
Leaks, cracks and worn linings can often be repaired in place.
