A hot dipped galvanising plant, of which the acidity of the atmosphere was between 17-30%. Roof structure and sheeting had corroded to a point where the building was soon to be condemned. We provided a solution whereby new roof purlins installed were corrosion protected in terms of a polyurethane coating and stainless steel bolts to connect to structure. An Advanced reinforced fibre glass anti-corrosion sheet was installed which allowed for walk-on capabilities. Its translucent properties also allow for the benefits of natural lighting. The sheet is guaranteed for a minimum of 20years with minimal maintenance. This state of the art solution saved the client a projected R2.5million over 20 years.
