Offshore Spars’ aluminum mast and booms have custom design and manufactured, integrally welded components. We use no aluminum castings. All aluminum mast systems are primed and top coated using Awlgrip polyurethane finishes.
Due to the demand of carbon spars over aluminum masts, Offshore Spars has a limited stock of extrusions. The below table shows our current in stock offerings. If you have questions about on of these or an extrusion you do not see listed here please contact us.
