CasterHQ's 5" (Inch) Semi-Steel Wheels also known as Gray Iron Wheels are fully metal wheels and are less expensive than Ductile Wheels. Semi-Steel wheels are better for light to medium duty applications if used on smooth concrete floors and applications where they do not take any type of overloading, impact, or abuse. On floors such as untreated concrete, these wheels may cause the floors to decline and chip over time. Steel wheels are not meant to be used in applications with impact, shock, poor floors, floor obstacles or debris, overload, abuse, or any type of use with an automated powered towing system.
