Coronavirus – Phased Re-opening
Phased Re-Opening of PVC and Aluminium fabrication on 11 May following period of enforced shutdown due to Covid 19 Since we took the decision to temporarily shutdown the business on 27 March, which was designed to ensure the safety and wellbeing of our staff and customers as well as supporting the drive to reduce the potential impact on our NHS and community at large. We have been continually reviewing all news updates, Government advice, and numerous agency guidelines regarding what is deemed best practice for a suitable method and timescale to restart manufacturing, while honouring all guidance regarding the Covid 19 lockdown. During this period, whilst recognising the obvious economic and commercial pressures, we have always had at the forefront of our thinking the safety and wellbeing of our employees and customers, and we would not consider a return to business before it was deemed safe to do so, acknowledging that various personal distancing measures and site restrictions will continue to apply for the foreseeable future. Risk assessments have been completed, significant quantities of PPE and hand sanitiser have been purchased, and all sections of our business have been reviewed to ensure that we are able to adopt best practise for personal safety for staff and customers alike. These factors have enabled us to introduce a phased opening of Sterling with effect from Monday 11th May. We will start with a small number of staff and build back up to full production once all new processes and systems have been fully assessed. A consequence of some of our new procedures and systems is that some new site rules and restrictions will be in place across our business and we respectfully request that they are followed at all times. In order to protect our staff further and reduce the number of people coming to site, we request that customers email all surveys for pricing to [email protected] and email all confirmed orders to [email protected] We would like to thank of our staff for their hard work and dedication, and all of our customers for their continued support and business.
