The short version: Aluminum modular ramps with grit-coated tread handle wet climates best. EZ-Access Pathway HD with grit tape is our default pick. Wood ramps need pressure-treated lumber plus non-slip tread strips.
Material picks for wet conditions
| Material | Wet performance | Maintenance |
|---|---|---|
| Aluminum modular with grit tread | Excellent | None |
| Wood (pressure-treated) with non-slip strips | Good if maintained | Annual cleaning, 5-yr stain |
| Steel | Poor (rust without coating) | High |
| Composite (Trex etc.) | Good | Low |
Our picks
1. EZ-Access Pathway HD with grit tread
Heavy-duty aluminum ramp system designed for outdoor use. Grit-coated deck panels survive rain, snow, and ice better than smooth aluminum. About $2,000-$5,000 for a 14-foot configuration.
2. Custom pressure-treated wood ramp
Built to spec by a CAPS-certified contractor. Use 5/4 pressure-treated decking with non-slip strips at each tread edge. About $3,500-$8,000.
3. Composite Trex-decked ramp
Premium option using composite decking on aluminum or steel frame. About $5,000-$10,000.
Slip-resistance specs
ADA requires slip-resistant ramp surfaces; specifically the static coefficient of friction must meet or exceed 0.42 wet.1
For DIY-applied non-slip strips on existing ramps, look for outdoor-rated grit tape (3M Safety-Walk 510 series or similar). Replace annually.
What to do next
For wet climates, choose aluminum modular over wood unless aesthetic match matters more than maintenance.
