In the long term, sliding gates deteriorate at the point of friction of the guide roller, leading to the onset of corrosion that requires repainting. The most durable paints are powder coatings, which are also the most expensive, so it is important to protect them properly by using this guide roller made of polyurethane.
We applied a primer on the insert and then poured a high abrasion-resistant MDI type polyurethane. The thickness used is 3 mm, which will withstand many years of constant use.
