Description
GSPF U-Shim Pads, also listed as Packing Shim Pads, are polymer shims with an open U shape. Because one side is open, the shim can be slid into position around a bolt, plate or other protrusion without lifting the element fully off its support.
They are used to level and align precast concrete and steel elements during erection. They measure 70 x 100 mm and are available in six thicknesses from 1 mm to 10 mm, which gives fine control over height.
Key Features and Benefits
Open-sided shape
The U shape lets the installer place the shim around bolts and connection points, which speeds up adjustments.
Six thicknesses
Thicknesses of 1, 2, 3, 4, 5 and 10 mm allow small steps in height.
Durable, non-corrosive polymer
The material resists compression, moisture and deformation in demanding conditions.
For repeated use
The pads are made for repeated use in precast yards and field assembly.
Applications and Use Cases
U-Shim Pads are used for:
- Precast concrete erection that needs precise levelling
- Steel structure installation where shims must fit around bolts and plates
- Aligning beams, panels and structural frames during assembly
- Supporting baseplates, brackets and anchor points
- Precast yard operations with fast, repeated adjustments
