Under road galvanised steel culverts are utilised frequently throughout Australia as a cost effective alternative to bridges, enabling under road water flows.
Zinga provides galvanising-like performance when used as a maintenance coating on existing culverts. The life of the culverts can be extended to up to 30 years.
The culverts are prepared by low pressure water washing (3000psi) including the use of ChlorRid to assist in removing contaminants. The corroded areas are then spot abrasive blasted. Two coats of Zinga Liquid Galvanising is applied at 60 microns per coat by either brush, spray or roller.
With the significant extension to service life of the culverts, the Zinga system is now the preferred solution for maintenanceand is specified by VicRoads.
