Founded in 1975, JDP is headquartered in Glengarnock, Scotland employing 425 staff on projects across the UK.
Growth at the Ayrshire steel erector has been underpinned by the expansion of e-commerce logistics, warehouses and transport infrastructure.
Last year it achieved £87m turnover generating a £13m profit last year.
The existing management team will continue to operate the business led by managing director Derek Pierce, who will stay in the long term and remains a significant shareholder.
Pierce said: “Storskogen is a great cultural and business fit for JDP and we have shared ambitions for the future.
“I am really looking forward to the next phase of growth and continuing to build the business and relationships with the Storskogen team.”
JDP is Storskogen’s first acquisition in Scotland and the seventh in the UK since Storskogen launched in 2020.
Last month Storskogen bought an 80% stake Fabco Sanctuary, a leading manufacturer of steel windows, doors, screens and partitions.
The steelwork specialist will join Storskogen’s vertical Industrial Technology within business area industry.
Fredrik Bergegård, Head of Business Area Industry, will become DP chairman.
He said: “JDP is well-positioned for the future as one of the most well-invested and automated companies in the market.
“With Storskogen’s expertise in the industry, we see potential for great collaboration and knowledge sharing between our companies to achieve further growth together.”
