Will this ramp stay in place or does it need to be bolted down?

Mounting method is not specified — test-fit the ramp on your threshold or surface first. You may need adhesive pads, non-slip feet, or fasteners depending on your setup and whether you want it permanent or portable.

Is the non-slip surface textured or coated, and will it hold up to wet weather?

The ramp is finished in metallic black powder coat with a non-slip surface designed for wet conditions. The powder coat protects against rust and corrosion, but actual texture type and durability under constant outdoor exposure are not detailed — store indoors when not in use for longest life.

Can one person carry or move this ramp solo?

At 7 feet long and aluminum construction, it's designed to be portable, but exact weight is not confirmed. For safe handling, treat it as a two-person lift, especially over doorways or uneven ground.
