HORSE GYM USA® machines feature either commercial grade stainless steel to reduce the risk of rust and corrosion or hot-dipped galvanized frames for durability and weather resistance. The HORSE GYM USA® WALK has optional add-ons like a maintenance free roof to shade the horses while they’re working out. These factors make finding the perfect place for your new machine that much easier! Still concerned? Don’t hesitate to contact one of knowledge team members here.
