The sale of the three brands, which had been appointed liquidators from PwC in December 2022, was completed on 17 January.
Duraweld bought the three firms’ order books, trade names, branding and websites; their machinery and tooling; and materials such as vinyl and greyboard.
Mark Yeung, managing director of Duraweld, said the three companies - which specialised in plastic packaging and stationery - made an excellent fit for Duraweld.
He said: “There are some incredible synergies in the mindset and approach of Celsur and Duraweld - we operate in similar sectors and offer complementary products and levels of service.
“Adding these long-established brands to our extensive portfolio marks an exciting new phase for the businesses - we are looking forward to supporting their former clients, alongside our extensive customer base, all backed by Duraweld’s deep manufacturing expertise.”
The companies’ manufacturing will be relocated to Duraweld’s Scarborough site.
Yeung added: “It’s exciting to further expand our customer base during a period of such strong growth for Duraweld, with the move strengthening our position as the go-to business in this specialist sector.”
Duraweld, which employs around 50, has taken on several of the acquired firms’ staff, all of whom had been made redundant during the course of liquidation.
Yeung said: “We are pleased to welcome such experienced sales professionals as Emma Morris and Sharon Heath to the Duraweld family, and there will be more appointment announcements to come.”
Morris said: “It has been a challenging period, but I’m genuinely excited to be joining Duraweld. The team has been great, and I’m looking forward to providing continuity and ensuring a seamless transition for longstanding customers.”
Duraweld's triple acquisition came shortly after its purchase of Prima in November 2022, in which it folded the Bradford firm's business and assets into its own operations.
