If you’re working on a commercial or industrial build that requires heavy-duty alignment or load-bearing precision, metal shims are the answer. In this guide, we look at where and when they’re the right fit, how they differ from plastic shim alternatives and what to consider when specifying for your project.
What Are Metal Spacers Used For?
Metal shimming components are used when high compressive strength is required. They’re installed under base plates, machinery, steel columns or precast panels to level or align components, especially in high-stress or long-term-load-critical environments.
Because they’re made from galvanised or stainless steel, they also offer greater resistance to heat and deformation compared to non-metallic options.
Common uses include:
- Structural steel fabrication
- Tilt-up and precast panel installations
- Machinery or equipment levelling
- Cladding and façade installations
- Long-span or load-critical assemblies
While plastic packers are more common for general-purpose use, metal versions are used for engineered designs that require superior load retention or performance under pressure.

Benefits of Steel or Galvanised Packers
- High-load tolerance – Suitable for bearing heavy structural loads without compression
- Dimensional consistency – Manufactured to tight tolerances for uniform levelling
- Thermal durability – Can be used in high-temperature or fire-rated assemblies
- Corrosion protection – Galvanised and stainless variants withstand harsh site conditions
Where safety and compliance are non-negotiable, metal is the specifier’s choice.
Benefits of Steel or Galvanised Packers
If you’re unsure whether your project requires steel spacers or another material, it usually comes down to:
Consideration
- Load Requirements
- Heat Exposure
- Longevity
- Structural Certification
Choose Metal If…
- Load is high and plastic may deform
- Installed near hot works, machinery or fire-rated zones
- Long-term, non-serviceable installations
- Compliance documentation requires steel
In most cases, plastic shims are more than sufficient. But when engineers call for steel packing shims, it’s usually for a reason.

Steel Spacers FAQs
Are These Suitable for External Use?
Yes, especially if using stainless or galvanised versions. These are corrosion-resistant and suited to outdoor or marine environments.
Can I Use These Under Machinery?
Absolutely. They’re commonly used in industrial setups where plastic options might compress or shift over time.
Are Certifications Available?
Yes. We can supply materials with traceability and certification for structural applications.
