Doncaster-based plastic piping and ventilation systems manufacturer Polypipe Group plc said its revenue rose 8.4% to £242 million and profit before tax rose 5.3% to £31.5 million in the six months ended June 30, 2017.

Polypipe’s interim dividend increased 16.1% to 3.6p per share.

Polypipe is the largest manufacturer in the UK, and among the 10 largest manufacturers in Europe, of plastic piping systems for the residential, commercial, civils and infrastructure sectors by revenue and a leading manufacturer of energy efficient ventilation systems in the UK.

The group primarily targets the UK, French and Irish building and construction markets with a presence in Italy and the Middle East and sales to specific niches in the rest of the world.

Polypipe CEO David Hall said: “The group has delivered another record performance, building on the strong momentum from last year and demonstrating that our strategic focus on structural growth opportunities is delivering results.

“Although underlying fundamentals remain positive, the group has experienced varying conditions in its different markets and has also faced some challenges in the first half of the year.

“I am encouraged by the way the business has risen to these challenges which is further evidence of the depth and strength of management across the group.

“As a result of our growth initiatives, balanced exposure to our markets and overall performance, the board is confident that the group will continue to make progress in line with management expectations for the year.”
