Safety: our key consideration
Wherever an emphasis is placed on personal safety, special demands are always placed on product quality. The health of our children is a high priority, which is why we at Ketten Wälder GmbH have made it our mission to guarantee safety.
Stainless steel chains – chains with extremely high corrosion resistance and durability
At Ketten Wälder GmbH, we consider it not only our task but our duty to ensure the highest quality and safety when manufacturing stainless steel chains for playgrounds. For example, we use ring nuts with finger guards on request to protect children's little fingers.
When we manufacture the chains for climbing nets, suspension bridges, wobble bridges and chain mazes, and for individually configured articles for playgrounds, we use only high-quality stainless steels. cromox® PLAY guarantees safety in accordance with DIN EN 1176.
In order to keep our children safe and sound, our PLAY series stainless steel chains are subjected to special design safety checks. In addition, special surface treatments guarantee a clean, burr-free surface.
In addition to these safety aspects, our cromox® PLAY chains and accessories offer high strength, exceptional corrosion resistance and durability under all natural and human-induced stresses.
