Cotterman 10-Step Steel Rolling Ladder vs Rolling Ladder 10 Step Aluminum Serrated

Both are 10-step rolling ladders that reach the same 8.3 ft platform, so the choice comes down to material and platform size. The Cotterman carries a heavier 450 lb rating and a deeper, wider footprint for stability, while the aluminum ladder is lighter to push around and gives you a much larger 28 in deep platform. Buyers who move the ladder often and work at the top step favor the aluminum model; buyers who load it heavily or want a sturdier steel build favor the Cotterman.

• Choose the Cotterman if you need the higher 450 lb load rating and a steel build that stays planted under heavy use.
• Choose the aluminum ladder if you move the ladder between jobs and want a bigger platform to stand and work on.
