❓ Why is the HPS FENCE automatic coop door made of aluminium?

✅ Direct Answer: Aluminium keeps the moving mass low, so the motor draws less current and a battery set lasts longer, and it does not rust in a damp coop like steel does. The low mass is also what lets anti-pinch reversal react quickly enough to be safe around birds.

📖 Details: Aluminium keeps the moving mass low, which is the whole point of the design: a lighter door needs less motor torque, draws less current and extends battery life. It also does not rust in the damp, ammonia-rich air of a coop the way steel does, and the low mass is what allows anti-pinch reversal to react quickly enough to be safe around birds.

📋 Buying note: When comparing doors, ask for the door weight and the current draw. A heavier steel door with the same motor and battery will need replacing sooner, which shows up as warranty cost for the dealer.
