Staal coaten met de hand hoog

Step 1/5 - How it works


The steel constructions are hung on a hanging rail and automatically blasted clean (according to the SA2.5 standard) to remove any rust or other contamination. The remaining steel grit is then removed with compressed air.

Step 2/5 - How it works

Manual powder coating

In the hand powder cabin, difficult-to-reach corners are coated by hand by our employees and a few powder guns.

Step 3/5 - How it works

Automatic powder coating

The steel is given a corrosion-resistant powder coating by means of 24 fully automatic powder guns. A powder recovery system prevents powder waste and allows us to reuse surplus powder.

Step 4/5 - How it works


The structure is cured in a 90-metre long conveyor oven. In the second line, the construction goes into a closed oven.

Step 5/5 - How it works


Before the steel leaves the conveyor belt and is loaded onto the trailer, it is thoroughly checked for layer thickness and quality. Any overlaps are corrected by hand.
