Sinead Leadbeater
Sinead joined Langley Alloys as the company's very first apprentice and has spent 18 years with the business, building extensive knowledge of our full range of specialist alloys as she progressed alongside it.
She works on the larger, more complex projects across oil and gas, marine, defence and nuclear, supporting customers throughout the UK. Her strength is reading and interpreting demanding specifications and pinning down the testing, certification and project requirements that come with them.
Sinead came up through the business from that first apprenticeship, completing a Level 3 Business qualification as part of it and later gaining a Diploma in Management. Eighteen years on, she has grown with the company and knows both its alloys and the industries they serve inside out, from oil and gas and marine to defence and nuclear.
She enjoys the variety of the role, particularly the technical side of the business, solving complex challenges and building strong relationships with customers, some of them going back to her earliest days at the company. Away from work she supports charity fundraising and spends her time with family, friends and her little sausage dog.
Mathieu Tremaux
Mathieu has spent over 16 years in the metals industry, the last 13 with Langley Alloys. A French national who has lived in the UK for 29 years, he supports customers across Europe, from Poland to Portugal.
He works most closely with duplex and super duplex stainless steels and nickel alloys, the grades Langley knows best as the developer of the original super duplex, Ferralium® 255. Customers come to him for cost-effective answers on design, machining and project delivery.
Mathieu came into specialist alloys after a career in sales and business development that began in Germany and continued in the UK, across industries from airlines to printing. He studied at the INSEEC business school in Paris and read economics at the University of Kassel, and speaks fluent French, German and English.
He sees sales as building bridges, and his feel for cultural differences and international experience, including becoming something of a Brexit expert, have built relationships across European markets, backed by the wider Langley group's finishing capabilities. Away from work he is happiest outdoors and walking, follows Arsenal, and has long swapped croissants for oatcakes, though he is more a beer connoisseur than a wine taster.

Darren Greer
Darren has spent his entire working life in engineering and metals, including over 18 years with Langley Alloys and a decade before that at Meighs Castings. He now leads the Majors section, supporting oil and gas OEMs and independent down-hole tool companies across the USA, UAE, Singapore and Saudi Arabia.
His focus is raw material, bored bar and competitively priced turnkey machined parts, with recent high-volume work in nickel alloys 825 and 925, 316 and 25Cr super duplex.
He came into metals through a four-year engineering apprenticeship at APV Chemical Machinery, then moved into metal sales at Meighs Castings, where he project-managed machined nickel-aluminium-bronze castings for the defence sector, focused on submarines. He holds an HNC in Engineering and a Foundation Degree in Project Management.
Colleagues have called him a broad-based specialist: with decades in the industry, customers come to him for all sorts, from sourcing and pricing to questions on material specifications and quality requirements. Away from work, he played 8-ball pool at county level and later turned professional on the UK 9-ball tour.
Rodney Rice C.Eng
Rodney is a qualified metallurgist and Chartered Engineer with almost 35 years in the metals industry, the last 10 with Langley Alloys. As Sales Director he draws on a career spanning technical support, product development, R&D and marketing across the UK, the USA and beyond.
He works most closely with super duplex stainless steels, alongside a wider range of high-performance stainless steels and nickel alloys, helping customers find the practical, cost-effective route to their requirements.
His career has spanned carbon steel flat products, organically coated steels and, more recently, high-performance stainless steels and nickel alloys, with extensive travel supporting customers and business development around the world.
Naturally curious, he believes the best way to answer a customer's question is to understand it fully, and he supports the sales team wherever his experience adds value, particularly on unusual applications and technical questions. He enjoys the variety of the role, moving between supplier relationships, daily operations, major projects and exhibitions. Away from work, he starts most weekdays in the gym, and at weekends you might find him walking on Moel Famau, following Coventry City, or spending time with family.
