Steel gauging plates are manufactured from high-grade steel stock and machined to customer specifications with low tolerances. Options include varying thickness; cut slots along circumference for deflection sensitivity; customized dimensions for specific applications. We are capable of manufacturing larger sizes, but due to fluctuating aluminum/steel costs, we cannot post prices. Also, 1/4″ thickness is the standard for gauging plates, but we can manufacture in 1/8″, 3/8″ and 1/2″ thickness if desired.
