To all our valued Suppliers and Customers

The factory has now re-opened with a skeleton staff and operating at a limited capacity to complete work on existing orders. Unfortunately we can only accept deliveries at this time if they have been specifically agreed and arranged in advance. We are constantly monitoring the situation and hope to be back into full production as soon as external conditions allow. In the meantime we thank all our valued suppliers and customers for their patience and understanding.
