The only specialist steelwork fabricator capable of designing and manufacturing the optimum technical and commercial mix of Westok Cellular, Plate Beams and Shallow Floor Beams.


The Beginning

Westok Structural Services Limited was established in 1985, as a subsidiary of the Wescol Group, to supply castellated beams to the fabrication industry.

During the late 1980’s

After full scale tests at Bradford University, design consultation with the SCI and a granting of a patent for the cutting process, the cellular beam was launched to the UK construction market.

Westok Limited

Formed from a management buyout, we continued to grow the cellular beam market and also introduced the Ultra Shallow Floor Beam.

ASD Metals

In 2007 Westok Limited was sold to ASD Metal Services Limited (part of the Kloeckner Group) and ASD Westok Limited was formed.

2014 Development

The Westok Plate Beam software package was launched to complement the Westok Cellular beam software – which remains the UKs most used, trusted and unrivalled software for the design of cellular beams.

2016 Rebrand

We are now trading as Kloeckner Metals UK | Westok and have continued investment to ensure that we stay at the forefront of technical abilities within our factory.
