The investment will create a "considerably expanded" supply chain capacity expanding the Telford site while closing at Hull.
This will create additional manufacturing capability and provide an additional UK distribution site in the south east of England.
A new £30m manufacturing facility opening this autumn in Grudziadz, Poland will enable further commitment to high quality product development as Grange continues to focus on product differentiation throughout its existing ranges and its new product development plans. The site will also add capacity for greater volumes of product in response to demand and ensure consistency of materials and manufacturing quality.
The new distribution site in the South East, with its supply links to the new Polish manufacturing facility, will improve distribution across the board creating a number of operational efficiencies, say Grange. This will shorten lead times, enable improvements in customer service and create a stronger distribution network working in tandem with Grange’s Telford headquarters and production site.
At Telford itself the investment will enable improved speed of service and additional storm cover product availability, as well as develop productivity and distribution capability, say Grange. There is a consequent proposal to close the company’s Hull-based manufacturing and distribution facility, which is currently going through a consultation period.
Managing director Neil Taylor said: "Recent investment from Stelmet has been extremely positive in terms of sales volume and customer gains. The company is now increasing both its production capacity and its supply chain efficiency in order to ensure it can deliver growth.
"The company continues to forge ahead with online and offline promotional and communications activity, including a new website, increased social media presence and ongoing trade and consumer PR and advertising. The Grange team is committed to providing customers with stunning products, quality service and a real opportunity to maximise consumer appeal."
