Something About Us

Our Story

Our founder, Inam Gardezi, worked in the engineered shim space industry in the 1960s. Realising the limitations of a rigid material like steel and the challenges of easily distinguishing the thickness, he had the idea of using colour-coded polymers for each gauge of material.

His simple idea launched an entire industry. Plastic Shims & Gaskets was subsequently born from Inam’s home in Bethnal Green, London, in 1969. In doing so, he brought this brand-new innovative solution to the global marketplace.


“In this image Inam Gardezi is leading our London based operation before the dawn of IT filled offices, he can be best described as a thought leader in the engineered shim space.”
