These types of conveyors are not enclosed, convey heavy loads, and may present hazards to young employees who load and unload them. 14- and 15-year-olds are prohibited from operating such conveyors under both 29 CFR 570.33(k) and the Child Labor Reg. 3 general prohibition against operating or tending power-driven equipment.

When steel is rolled back-and-forth through the same mill, this is a reversing mill. When it moves directly in a continuous process to other mill stands, this is a tandem or continuous mill. These can achieve far higher throughputs than a reversing mill. Tandem mills are associated with flat products and typically have 4 or 6 stands.
