Durable powder coating

Decorative bollards feature powder coatings to ensure lasting durability that will resist weathering and corrosion. Powder coatings are available in a range of colors, which ensure the best visibility for road bollards.

If you contemplate about rather buying new traffic bollards instead of hiding your rusted, old bollards with plastic sleeves, it´s recommended choosing specially treated security posts.

Meanwhile, it is common to install hot deep galvanized and powder-coated ram bollards. More bollard manufacturers, like Sino Concept, offer bollards with hot deep galvanized steel and powder-coated finishing to ensure rust free, colorful, long-life bollards.

No matter if you prefer bollard post covers or powder-coated bollards in future time. Both solutions guarantee a long durability of your bollards.
