Longley Concrete has sold Whites Concrete to Naylor Concrete Products.
Whites has a turnover of £2 million (€2.5 million/US$3 million) and makes pre-cast and pre-stressed concrete products.
Naylor said the deal would extend its product range.
Production will move from Longley's site in Dewsbury to Naylor's plant near Barnsley, northern England.
