Buying Guide: Practical Considerations for Aluminum Pontoon Decking and Corner Caps

What to look for in corner caps for 90° rounded pontoon corners

  • Compatibility: confirm height, top width, and radius align with your pontoon deck edges.
  • Material: cast aluminum with powder coating provides marine durability and rust resistance.
  • Finish and installation: powder coat resists UV and salt; bolt-on installation reduces the need for welding.

Choosing between aluminum corner caps and alternate decking materials

  • Corner caps: prioritize protection of deck edges, a tight fit, and long life in harsh environments.
  • Decking: EVA foam or faux teak options improve foot comfort and traction, especially on hot days.
  • Weight and maintenance: aluminum components add stiffness and durability; EVA flooring reduces weight and provides cushioning but may require more care against wear.

Fit and measurement tips

  • Measure both height and top dimensions precisely; look for product pages that list these measurements clearly.
  • When in doubt, contact the seller to verify compatibility with your pontoon model and corner radius.
  • Consider buying multi-pack corner caps if your pontoon has multiple corners requiring edge protection.

Installation considerations

  • Some corner caps use bolt-on installation, which simplifies mounting without welding.
  • Check for required tools and confirm whether reinforcement or drilling is needed.
  • Plan for alignment with other decking components to maintain a uniform appearance.

Durability and maintenance expectations

  • Aluminum caps with powder coating are designed to resist corrosion and maintain appearance in saltwater or humid environments.
  • EVA flooring requires cleaning and occasional resealing or replacement depending on usage and exposure.
