Shims suit large, heavy loads

Large flat plate shims and micro-grid shims are the newest additions to Grove Products’ line of solid structural shims used in construction, restoration and industrial installation. The company manufactures shims out of 100 percent recycled plastic, and every shim style and size is available in fireproof materials on request.

Structural shims are used for a wide range of spacing and leveling applications, both on a temporary and stay-in-place basis. They are commonly employed in door, window, and other glazing installations; for leveling very heavy objects such as tilt-up concrete walls, precast concrete panels and other large structural elements; and for leveling heavy machinery installations.

“A shim is a humble but essential tool,” stated David Braune, president of Grove Products, Inc. The large flat-plate shims, 8- x 8- x 1-in. thick, are designed to bear large heavy loads, with strengths up to 4,000 psi available. They’ve already been employed for leveling decks, structural members, and large, water-tanks. Micro-grid shims are designed to stack securely, using increased shim-to-shim friction due to mated grids on the shim’s surfaces. The grid patterns interlock the surfaces of stacked shims to resist lateral slippage. They are initially available in 4 x 6 in. in thicknesses ranging from 1/16 in. up to 1/2 in. and can be stacked to adjust heights with compressive strengths up to 6,000 psi. The family-owned Grove Products is celebrating 50 years in business this year.   —
