Technical & procurement detail
What plastic shims do+
A shim carries load across a gap that the structure was never built to close. It holds a frame, base plate or fixture at the correct height and line while it is fixed, and unlike timber packers it does not absorb moisture, rot or compress unpredictably over the life of the installation.
Common types within this family+
This page covers the family as a whole: flat rectangular packing shims, horseshoe (U-slotted) shims, tapered and wedge-style packers, colour-coded thickness ranges, assorted-thickness site packs. Individual sizes, threads, colours and geometries are quoted from your specification rather than listed as separate products.
Material options+
Shims are commonly moulded in polypropylene or high-impact polystyrene, and are often colour-coded by thickness so an installer can identify a size at a glance. The material, colour convention and load behaviour offered are confirmed with the supplier for your application.
Selection considerations+
Work from the gap you actually need to close and the way the fixing passes through it: a horseshoe slot lets the shim be fitted or withdrawn around a bolt that is already in place, while a plain flat shim suits a clear bearing surface. Then confirm whether the shim is load-bearing under a structural element, because that decides the material and the stacking method rather than the size.
What to include in your enquiry+
Send the thickness or thickness range needed, the plan size, whether a slotted or plain shim is required, the colour convention you already work to, the load the shim sits under and the quantity per size.
Documentation and specification+
Allzone confirms material, dimensions and connection detail with the supplier before quoting, and shares the technical drawing and material declaration for the exact part offered. No dimension, pressure rating, material approval or certification is assumed on this page — every value is verified against supplier documentation at quotation.
Frequently asked questions
What is the difference between a flat shim and a horseshoe shim?+
A horseshoe shim has an open slot so it can be slid around a bolt or fixing that is already installed, and withdrawn later. A flat shim has no slot and is used where the bearing surface is clear.
Are shims colour-coded by thickness?+
Most site ranges are, but the colour convention differs between suppliers. The convention for the range being offered is confirmed at quotation rather than assumed.
Can you quote against a drawing or a sample part?+
Yes. A drawing, a photograph or an existing part reference is usually the fastest route to an accurate quotation for a moulded component.
What quantities are quoted?+
Quantities are reviewed per enquiry. Moulded components are normally quoted per carton or per container load depending on the part and the programme.
Are certifications available?+
Any certification, approval or rating is confirmed for the specific supplier and part at quotation. Nothing is claimed on this page in advance.
