| Coating System |
All underwater parts are given two coats of marine epoxy primer followed by a marine urethane top coat. Above water parts are first coated with a zinc rich primer followed by a marine epoxy primer and top coated with acrylic polyurethane. The deck is also given an anti-skid surface. The minimum paint thickness for below and above water coatings is 12 mils, not including OEM coatings. |
| Current Specifications Subject to Change |
These specifications are representative of a typical swinging ladder dredge design, but are subject to change at manufacturer's discretion when necessary to update the product, and to provide the best available technology that optimizes dredge performance, improves quality, and best satisfies our customers' needs. |
