Surface Coatings
Corrosion protection is just as important as the manufacturing process when fabricating steel structures. That’s why us at Cairnhill go above and beyond to ensure we offer a system that works with the application of the product and meets the required specifications.
Working with our supply partners we can offer full protection using wet paint systems.
Paint is the most commonly used material to protect steel. Paint systems for steel structures have developed over the years to comply with industrial environmental legislation and in response to demands from bridge and building owners for improved durability performance. Previous five and six coat systems have been replaced by typically three coat alternatives, and the latest formulations have focused on application in even fewer numbers of coats. Whatever your requirement we will be able to offer advice on a solution that works for you.
Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
