Rotomolded Plastic Dock Box vs Fiberglass
DPI Rotomolded Plastic
- Extreme Impact Resistance: Flexes under pressure to absorb heavy impacts without breaking.
- Zero Maintenance: The “forever material.” Just rinse it with a hose. Never requires painting or refinishing.
- UV & Weather Proof: UV-stabilized polymer refuses to chalk, turn yellow, or fade in harsh sun and saltwater.
- Seamless Construction: Molded as one continuous, uniform piece with no weak corners or structural seams.
- Luxury Wood Grain Finish: Features a premium, molded wood grain texture that hides minor scuffs and elevates your dock.
Traditional Fiberglass
- Brittle & Fragile: Highly prone to spider-cracking, chipping, and fracturing under heavy impact.
- High Maintenance: Requires annual waxing, compounding, and expensive gel-coat repairs to maintain its look
- Sun Degradation: Gel-coat breaks down under UV rays, turning chalky, dull, and yellow over time.
- Inconsistent Strength: Hand-laid layers often have thin, weak spots along corners and seams that can split.
- Plain & Spartan: Standard glossy white finish that easily shows every scratch, scuff, and scrape.
