The walkways, same as our barges, are made out of a corrosion resistant isophthalic polyester resin reinforced with fiberglass mat and woven roving. The interiors of the units are filled with closed cell polyurethane foam, so that even if they become damaged, the damage will not affect the flotation of the units. All of the walkways include an exterior ultraviolet resistant coating. The gelcoat is a white-pigmented sealer that protects the barge from corrosion and ultraviolet rays. All of the walkways come with handrails and kick plates that meet MSHA requirements. The top surface is skid resistant to prevent accidents. We even created a new design for the handrail system and the connecting brackets to make it safer and stronger. The connecting brackets are made out of stainless steel as well as all the studs.
