Powder coated screws

Here at RALfixings we believe it's the little details that make the big picture. That's why we powder coat all our screws and fixings to any RAL colour your project requires. Powder coating involves spraying the fixings with a coloured powder, then super heating them to fuse this powder into a protective layer. Powder coat finishes are more durable than painted finishes. Powder coating can protect metal for as long as two decades.
