For saltwater applications, stainless steel is well worth the extra cost. Whether the tubing is drawn or extruded has a profound effect on the strength of the tubing. Drawn tubing is pulled through the die process, giving it a denser consistency and more strength. Extruded tubing may have weak spots because it's pushed through the die process. Fittings Fittings are available in nylon and stainless steel.
Nylon is relatively strong and weather resistant.
Stainless fittings are more expensive, but are the strongest and most durable. Coated brass fittings are inexpensive but they have a tendency to corrode and peel. Helpful Accessories Slide tracks allow you to install the top onto the track rather than directly onto your boat so you can slide the entire bimini to different locations. This also makes it easier to fold the top down in the optimal location when not in use. Storage Always take the bimini down for winter storage.
