The Penta Promise

History

Penta has come a long way since it was founded in 1998 by 5 people (hence the name Penta). 

We started out manufacturing tooling for an international computer manufacturer before developing our skills to encompass the aerospace, marine and fabrication industries amongst others.  

In 2007 we doubled our capacity, moved to larger premises and subsequently implemented an ERP system, resulting in improved traceability and archiving facilities. 

Soon after, Penta gained ship to stock status with a major aerospace customer, having attained a 99% quality performance for 2 years, and has maintained this standard since.

Penta is currently looking to expand further and invest in new premises, machinery and people to continue to increase capacity and broaden our range of services.
