SM87 LU1/3 Range of Steady Beacons

These certified steady beacons have been designed for use in harsh environmental conditions. The marine grade stainless steel or alloy enclosures are suitable for use offshore or onshore, where lightweight combined with corrosion resistance and strength is required.

Units can be painted to customer specification and fitted with identification labels.

Stainless steel, one of the most durable materials available on the market, is both hard wearing and corrosion resistant, increasing the life of products in harsh environments and therefore reducing maintenance costs.
