Painted Steel Production and Properties from Surdex Steel

surdex steel

The valuable properties of steel are well known. It is strong and hard. At the same time, it is easy to form into different products without losing its main properties. The only drawback of this alloy is that it is not fully resistant to corrosion. That is why various technologies for its protection have been invented and are constantly improved. One of them is painting. Painted steel has greater corrosion resistance and often better aesthetics as well.

Paint is applied on readymade steel products. It is important to note that it can be applied as part of the manufacturing process or afterwards by the buyer. This gives buyers more customisation options.

Painted Steel: The Painting Process

This process involves the application of different types of paint. They are applied in layers. Each layer serves a specific purpose. After the metal has been thoroughly cleaned, primer is applied. This is the first layer. Its job is to prepare the surface for the better adhesion of the following layers. It is possible for you to purchase primed steel directly and paint it by yourself.

After the primer, the so called intermediate coats are applied. They work to make the paint thicker so that it can provide adequate environmental protection for longer. The finish coat is applied last. It acts as a barrier between the metal and moisture, chemicals, UV radiation and all other factors of the environment.

Stripe coasts can also be applied. They are applied to the edges and corners of the ready products in order to provide additional protection. This is necessary because paint tends to move away from these areas during drying.

When painted steel is ready, it retains is strength and hardness. It is more resistant to corrosion and has a colour which matches the specific application. It has a fairly long useful life. Repainting will be required. The frequency will depend on the thickness of the coating and on the specifications and quality of the paint.
