The Benefits of Using Packers and Shims in Construction

Getting alignment, level, and support right the first time is critical on any job site. Whether you’re installing doors, framing windows, levelling steel, or managing structural tolerances, packers and shims are the small tools that make a big difference.

Used across commercial and industrial construction in Australia, these simple components help you adjust, space, and support with speed and accuracy, reducing rework and ensuring compliance.

In this guide, we break down the practical benefits of packers and shims, where to use them, and why quality materials matter on site.

 

What Do Packers and Shims Do?

Packers and shims are used to:

• • Fill gaps between materials
  • Level uneven surfaces
  • Align panels, frames, beams, and fixings
  • Distribute load evenly across surfaces

They’re essential for installers, builders, and engineers working on everything from concrete panels and facades to glazing, flooring, cladding, and more.

Shims are typically thinner and used for fine adjustments. They can be stacked to achieve exact tolerances.
Packers are usually more robust and often used for spacing or levelling heavier components.

At PP Shim, we supply both plastic and metal options in a wide range of sizes, including custom-cut shim solutions to suit non-standard installations.

 

Common Shim Types and Their Uses

Plastic Shims

Durable, moisture-resistant and colour-coded by thickness. Ideal for external cladding, façade work, and non-corrosive environments.

Steel Packing Shims

High-strength and non-compressible, used under heavy loads or in structural applications. Stainless steel shims resist corrosion in coastal or exposed environments.

Brass and Copper Shims

Non-sparking, conductive and corrosion-resistant, common in specialist electrical, marine, or high-precision work.

Slotted Shims

Allow precise positioning around bolts and anchors without disassembly. Available in pre-cut kits for speed on site.

Custom Shims

Made to your spec using in-house laser or water jet cutting. We also supply stamped washers and shim stock in various metals.

Why Builders Use Packers and Shims

Precision – Achieve exact tolerances and fix misalignments without starting over.
Time Savings – Quick, low-effort adjustments reduce delays and costly rework.
Load Distribution – Evenly support weight and prevent sagging or distortion.
Versatility – Available in multiple thicknesses and materials for every type of build.
Better Finishes – Flush, professional-grade installations every time, from frames to facades.
Secure Fixings – Used with the right screws or bolts, packers and shims create a stable, long-term hold.
