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

- 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.
