Delivering engineering excellence

Market-leading turnaround times

Alexander Comley was established in 1920 and subsequently became one of the pioneers of stainless steel manufacturing. Today we are a leading British-based company, located in the Midlands, exporting globally. We specialise in the manufacture of tubesheets, customised, high integrity flanges and pipe fittings. Example materials include stainless steels, duplex (F51), super duplex (F53, F55), nickel & mixed alloys, carbon steels (F22, F65, LF2) and low alloys.

Our on-going success is based on a combination of three vital factors: a continuous programme of investment in the latest machining technology; a highly-skilled workforce; and a thorough understanding of the requirements of the oil and gas, defence and marine, petrochemical, power generation, and process plant industries.

By bringing these together, we can deliver products of the highest quality within short time frames – a significant advantage for our clients.

Whilst customised manufacturing services are the focus of our business, we appreciate that for many customers off-the-shelf solutions tick all the boxes. We therefore also carry stocks of standard products and hold steel bar in stock for cutting to size.
