Today, with insights from Packers & Shims, experts in steel shims, we’ll unravel the various aspects of steel shims for you.
Understanding the Different Kinds of Steel Packers
Steel shims, also known as steel packers, act as fillers, bridging the gaps between objects. While steel is a common material, shims can also be crafted from other materials, including plastic. They’re available in diverse shapes and sizes, encompassing square, horseshoe, and rectangular configurations, among others.
Square-shaped steel packers are commonly used in applications requiring uniform stress distribution. Their symmetrical shape ensures equal weight distribution on all sides, making them a reliable choice for load-bearing tasks. With a U-shaped contour, horseshoe-shaped packers are specifically designed to facilitate adjustments around bolts, pipes, or any other cylindrical elements. Their unique shape allows for more flexibility, especially in environments where space is limited or adjustments around other fixtures are necessary.
Uncoated steel packers from Speedy Fixings are the most basic form, made directly from high-strength steel without any protective coating. While they offer strength and durability, they might not be suitable for environments prone to moisture or corrosive elements as they lack the protective zinc coating found in pre-galvanised and spun galvanised steel packers.

Pre-galvanised steel packers undergo a process where the steel is galvanised before it’s shaped into a packer. This means the zinc coating is applied to the steel sheets prior to fabrication. The primary advantage of pre-galvanised packers is that they have a smoother finish. However, the edges might be exposed to potential corrosion since they are cut post-galvanisation.
Spun galvanised steel packers are manufactured using a process where the packers are first shaped and then galvanised. This ensures all surfaces, including the edges, receive a protective coating of zinc. The result is a packer with enhanced corrosion resistance, making it ideal for environments where they’re exposed to harsh weather or chemicals.
While square and horseshoe shapes cater to different structural needs, the material—whether it’s pre-galvanised, pure steel, or spun galvanised—determines the packer’s longevity, strength, and resistance to environmental factors. Choosing the right steel packer from Packers & Shims requires an understanding of both its shape and material and your intended application, read this handy guide on buying packers and shims online that will help you make your choice.
