Trusted to deliver
Core Plugs International™ are the only supplier in the UK (and possibly the world) that stock the biggest range of core plugs in various metals.
While our main focus is on mild steel, stainless steel, and brass, we also offer other metals such as copper and aluminium upon request. The estimated lead time for obtaining materials, pressing, and delivery ranges from 5 to 20 working days.
For custom-sized plugs or sizes not currently listed, a lead time of 4-6 weeks is necessary to finalize specifications and create tooling. Additional fees will be charged.
Bulk discounts are applied automatically at checkout, ranging from 10% to 50% off the total amount (beginning at £20), excluding postage.
Please note: Due to the difference in names, a 'Core Plug' - either 'cup' or 'dish/welch', can be referred to as the following misnomers: Freeze, Frost, Expansion, Saucer and Welsh. See our Frequently Asked Questions page for more information.
