The MOD35 modular heavy-duty in-ground lift series’ features that are designed to fight corrosion include nitriding, electrocoating and zinc/aluminum coating. The nitriding heat treatment process creates a hardened surface that is hard to scratch so rust can’t get underneath it, according to Rotary Lift. The MOD35 frame is also electrocoated; paint is electrically bonded into every nook and cranny for a long-lasting finish, company officials said. Additionally, all fasteners are treated with a duplex coating system that prevents rust and seized bolts.
