Metal Shims

Mercer Gasket & Shim specializes in manufacturing custom shims and spacers for industrial OEMs, power generation, and petrochemical industries.

Shims are thin pieces of material that are used to fill up the small spaces or gaps that exist between two objects. They serve many purposes, including providing support, adjusting fit, or leveling out uneven surfaces. Many industry professionals create shims from whatever materials are available when needed. However, higher-quality shim stock is available commercially in a variety of materials, including wood shim stock, plastic shim stock, and metal shim stock.

At Mercer Gasket & Shim, we specialize in the design and manufacture of custom shims and spacers for industrial OEMs, power generation, and petrochemical industries. Equipped with over 80 years of experience developing and delivering custom industrial product solutions, a highly-skilled manufacturing team, and high-tech manufacturing equipment, we have what it takes to produce shims and spacers in virtually any shape, size, or complexity.
