Sealand Engineering, a company formed over sixty years ago for the purpose of manufacturing valves to supply to the maritime and land-based utility companies etc., hence the name Sealand.
Over the years the company has grown and built up a large customer base and which was passed on to the next generation where it still continued to flourish despite the influx off cheap imports.
Mainly by specializing in quality valves with full traceable and with certified parts and fully tested in house and if required witnessed by independent testing organizations.
In 2016 Sealand entered in to discussion with Acetarc Welding and Engineering a company with some fifty years’ experience suppling into the Foundry industry both in this country and overseas (in fact most of Acetarc’s products are exported).
Over the years there had been beneficial cross trading between the two companies, we use the same type of machine tools and workshop practices, so when the directors of Sealand expressed desire to exit their business the directors of Acetarc entered in to discussion with a view to acquiring the business.
The business of Sealand Engineering was duly acquired in June 2017, the process of merging it into the Acetarc site will be fully complete when the new built factory extension is completed, into which Sealand will be accommodated. This building will give Sealand the chance to continue to grow and flourish.
