Grenville Engineering: Sheet Metal Fabrication Since 1984
From a small Stoke-on-Trent workshop to a complete fabrication and precision engineering partner
Grenville Engineering – Our History
Over 40 years of sheet metal fabrication and engineering expertise
Grenville Engineering was established in Stoke-on-Trent in 1984 by John, Helen and Mark Barratt, with five dedicated shop floor employees.
We began in a Portakabin and a small workshop, equipped with a manual punch and a Strippit machine. From these modest beginnings, we have grown into a 58,500 sq ft sheet-metal fabrication and precision-engineering company supporting customers across the UK.
Building the foundations
Grenville Engineering was founded during a challenging period for British manufacturing, and our early team relied on practical engineering knowledge, flexibility and a shared determination to build a dependable fabrication business.
John Barratt brought valuable experience from the defence and automotive industries, along with a strong belief in investing in manufacturing technology.
In 1985, we formed an important partnership with a leading company in the earth-moving industry. This relationship helped establish Grenville Engineering within the fabrication sector and continues today.
We also began supplying customers in the automotive industry, producing large-volume batches and developing valuable experience in repeat manufacturing.
