Derek Brown

Managing Director

With over 30 years as a product specialist within the construction industry, Derek’s most notable success was originating the first reinforcement continuity strip product to achieve widespread appeal, ‘Kwikastrip,’ which he built to become the market leader, before being acquired by Halfen in 2001. More recently, after more than a decade in high profile positions within the supply sector, Derek recognised the opportunity to renew his owner-manager experience and teamed up with the Norwegian manufacturer, Invisible Connections AS, to become their UK partner. At the same time, Derek renewed his manufacturing leanings by establishing the current factory in Thame, Oxfordshire, principally to manufacture the FERBOX reinforcement continuity system.

Derek places high value on building long-term relationships with customers, suppliers and colleagues via an honest and earnest style of management.

Lesley Brown

Finance Director

Lesley has enjoyed a long career in finance, working freelance for several SMEs. She is used to collaborating closely with owner-managers and producing detailed management accounts, which she supports with interpretation and advice. Lesley has worked for architects, developers and together with Derek for many years, so is familiar with the customs and practices of the construction industry. She takes pride in doing as she says and does her best to inspire a similar mindset in her financial counterparts at customers and suppliers!

Steve Fordham

Technical Manager

Steve is an experienced mechanical engineer who brings crossover skills acquired whilst working within various steel and concrete disciplines. Steve’s primary focus is to technically support the growing customer base for telescopic connectors and to share his understanding of the many benefits this construction method brings to all members of the specification and construction chain. Steve is happy to present lunchtime seminars at specifiers’ offices and conduct toolbox presentations for ‘hands-on’ users.

Ross Tew

Ross brings a wealth of experience from the construction industry, most recently leading the sales office for a specialist building and construction accessories supplier. Having also had technical experience with an international fixings specialist, Ross is adept at finding the best practical and commercial solution for the customer and takes pride in building a great ‘customer experience’.

Anthony Mather

Production Manager

Anthony has been involved with the manufacture of reinforcement continuity systems for some 20 years, so understands very well the characteristics unique to the product, as well as the requirements of customers who depend upon a timely and reliable service. In addition to overseeing all aspects of production and CARES quality management requisites, Anthony also manages transport and logistics, ensuring deliveries are distributed nationally and individual site requirements for suitable vehicle type (FORS) and booking in slots are accommodated.

We hadn’t typically gone the ‘specials’ route before. But, by investing a little upfront time to schedule our FERBOX requirements, we gained a smooth supply and installation process - without wastage or complication - and exceeded the programme demands of our slip-formed cores.
