The Marine sector is a diverse market covering the needs of the private individual Yachting enthusiast and their chandlery, local dry docks, both traditional and innovative renewable wave technology and mainstream commercial shipyards. The demands of commercial ship building and ports involve high volume economically priced corrosion resistant fasteners with guaranteed delivery with technical support. Renewable wave engineering is predominantly low volume and requires rapid manufacturing of bespoke components following some material selection and fastener consultation. Yachting enthusiasts and outfitters require a tailored service, excellent workmanship and usually some detailed advice on material selection and fastener design prior to placing an order.
