2. Why can I safely leave my Metal Design (MD) garden furniture outside in the rain?

Every MD chair or table is anti-rust treated with zinc and powder coated in polyester colour. This paint is siutable for outdoor use. The paint has a good hardness, is durable in any weather and is impact resistant. For good anti-rust treatment the back and seat of Castrum chairs are made from stainless steel. That is the only way to prevent the rain water from causing rust where the stripes are welded together.
