Duplex combines the strength and durability of hot-dip galvanizing and paint in one single treatment.
In addition to offering hot-dip galvanizing to our customers, we can also offer a subsequent surface treatment, called Duplex. Duplex is typically used for outdoor items such as stands for stadiums, balconies or as guards for housing estates. Duplex is a practical, aesthetic and functional solution which extends steel's service life considerably.
Immediately after hot-dip galvanizing or galvanizing, the item is subject to a Duplex treatment. The secret of the durability is two extremely durable materials combined into one single protective layer. Paint combined with galvanization strengthens the surface and gives the finished product a quite unique durability considered the best possible corrosion protection.
From an overall financial view, the optimum solution is a combined production process including hot-dip galvanizing and Duplex paint. This means that one single supplier will be vouching for the quality of the total surface treatment, the delivery and the longest overall service life. Through more than 30 years, DOT has been refining the Duplex paint methods to ensure that the paint binds optimally to the surface of hot-dip galvanized steel and guarantees a long-lasting and maintenance free service life.
