The polishing of products of the pleasure-boating sector is varied because it presents different types of articles and shapes, ranging from very small articles (such as sideboards, stanchions, bases for stanchions, washers, roves, Plexiglas cradles...) polished automatically to more complex articles (such as bitts, plates for bitts, fairlead, logos, bent stanchions, locks, coupling for hauling part, single and double back-stands ...) that are worked on double-shaft polishing machines. Given the considerable size of ladders, anchor stanchions, handrails, handrail stanchions and pipes for table base, they are polished exclusively by hand with flexible pipes. Our distinctive feature: total elimination of weld marks between stanchion and handrail.
