Corrofit

Produkty

Superior corrosion protection for demanding environments.

Corrofit is the premium corrosion-resistant coating system developed by Piping Logistics for grooved couplings and fittings. Designed for fire protection and HVAC installations exposed to aggressive environments, Corrofit delivers exceptional durability, mechanical resistance and long-term performance.

With its advanced multi-layer protection system, Corrofit is specifically engineered to withstand tropical humidity, industrial pollution, coastal exposure,
UV radiation and insulated chilled water applications.

Built to last in the harshest conditions.

Engineered for lasting protection

Whether installed in industrial plants, coastal facilities, humid environments or demanding fire protection systems, Corrofit provides a reliable and durable solution that significantly extends the service life of your piping installation.

Maximum protection against corrosion

Corrofit uses hot dip galvanisation, advanced treatments and a UV‑resistant powder coating to deliver durable protection for grooved couplings and fittings.

Proven performance

Corrofit products have successfully
passed extensive salt spray testing and
are designed for long-term use
in highly corrosive environments.

Built for critical installations

Ideal for projects where standard painted
or galvanised products do not provide
sufficient protection.
