Company Philosophy

We have 4 key areas of responsibility:


is of prime concern to us. We operate within all relevant safety legislation, encouraging our employees to take responsibility for their own safety.


is to provide our customers with products which are consistently fit for their intended purpose and we achieve this by operating to ISO 9001:2015, developing products to meet the changing requirements of our customers and by encouraging a 'produce it right first time' attitude within our company.


in which we operate is fulfilled by being a good neighbour to the community of Barnoldswick and beyond. We achieve this by ensuring our operations not only conform to all relevant legislation but also by using operating methods which minimise their impact on the environment through continuous investment in modern process control systems.


in all that we do is the approach we use in all our operations. From the way we deal with customer enquiries, through technical development in our laboratories, process development in our factory, right through to product delivery, we are never satisfied. We believe in continuous improvement.
