About the Cover
John Suchmiel, an SMS Millcraft LLC employee, inspects a tread-plate roll to ensure the pattern meets industry-standard specifications. The company uses a proprietary method to produce tread-plate rolls at its Mokena, Ill., facility. This method is faster and less costly and produces tread-plate rolls that can last up to five times longer because fewer grinds are needed between retexturing.
