Goldseal Rustproofing Compound is considered by many as the premier Corrosion Control System on the New Zealand market. Goldseal has been used by numerous District Councils, Ports, Fertiliser Stores, Tanneries, Galvanising Plants and corrosive environments for well over 35 years.

In most cases, we are able to offer a 10-year “Rust free maintenance period”. This means your asset will not even start to show signs of corrosion for a decade.

We offer a range of other applications and services for our clients. With the help of our co company J L Connolly Ltd, we are able to offer the whole range of painting and decorating from industrial, commercial and residential. Between the two companies, we are able to call on the application services of over 45 team members so we are capable of handling those larger contracts without the need to employ subcontractors.
