Discussion Overview

The discussion revolves around the load capability of a 1/8" aluminum sheet used as a ramp for a power scooter. Participants explore the feasibility of using aluminum versus alternative materials for constructing a safe and effective ramp.

Discussion Character

  • Debate/contested, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant proposes using a 1/8" aluminum sheet bent to create a ramp and questions its weight support capability.
  • Another participant argues that 1/8" aluminum is insufficiently strong for ramp construction and mentions potential city building codes that may apply.
  • A third participant reinforces the idea that the aluminum sheet is not structural enough and suggests using common decking materials instead.
  • Another suggestion includes building the ramp with pressure treated lumber and adding no-slip strips or diamond plate for aesthetics and safety.

Areas of Agreement / Disagreement

Participants generally agree that 1/8" aluminum is not suitable for the ramp, but there are multiple competing views on the best alternative materials and construction methods.

Contextual Notes

There are mentions of building codes and structural integrity, but specific requirements or calculations are not provided, leaving some assumptions unresolved.

If I take a piece of 1/8" aluminum sheet that is 36" x 120" and bend each long side up 3" to create a ramp 120" long x 30" wide, How much weight would it support. My tenant has a power scooter and can't afford to purchase a ramp so I am looking for alternatives.

1/8" aluminum is not strong enough to be making a ramp with. Also, there are probably city building codes that will need to be met for the access ramp. It is probably best done as a woodworking project. Not sure of the best way to raise the money for it, though.
 
.125 Al sheet is hardly structural. You would be able to deform it with your hand, let alone a person on a scooter.

I think Berkeman is on the right track with using common decking materials.
 
thanks
 
I suggest building the ramp with pressure treated lumber and then putting 2 or 3 adhesive no-slip strips on it horizontally. Or if you want it prettier you could put diamond plate on it (the metal you commonly see on the running boards of trucks) You can buy it all at Lowe's.
