COVID-19 UPDATE: OPEN FOR BUSINESS
As providers of glass industries our manufacturing sites have continued to operate throughout the Covid-19 pandemic whilst adjusting to the new safe working and hygiene guidelines.
Many of our office staff, mainly of the sales team, continue to work from home, but a significant core of people are working from the office to facilitate production, administrative and logistic operations.
To maintain the health and wellbeing of our employees, customers and suppliers we will continue to follow these sanitary guidelines unless otherwise advised by the appropriate authorities.

To build relationships and network with the Glass Industry personnel from all over the world and find new business opportunities, SIGMA generally takes part in the major exhibitions and events planned in the year.
