The Alnwick-based company also recently changed its preservative treatment supplier from Osmose to BASF Wolman.

The third tank, with a weekly treatment capacity of 400m3, will increase A&J Scott’s treating capacity to 1,200m3 per week. Wiring and piping is currently being connected to allow the vessel to be in full production mode by the new year.

Managing director Robert Scott said the treatment expansion represented a £100,000 investment. He said the investment would enable A&J Scott to maintain its high standards of service through the busy treated fencing product season in 2013.

It also allows the company to increase its capability to offer green and brown finish treated fencing, while Mr Scott said Wolman had given great support, and its product gave a consistent colour. Treated products now make up more than 60% of all products manufactured at A&J Scott.

Mr Scott reported a good order intake during the month, with strong demand across the fencing sectors and also with sleepers and pallet timber.

“Having supplied treated timber for many years, we are delighted to be bringing this extra facility online,” he said.

“We’re well placed to offer high-quality treated fencing products and looking forward to building on the service levels we can offer to our valued customers throughout the year ahead.”
