Chairman’s Message

Since the inception of our business in 1976, SG Industries has been a pioneering force in Sri Lanka’s glass and mirror industry, with an impressive product portfolio and a loyal client base.

It had been a challenging yet fulfilling journey in making SG industries the largest glass importer and supplier in Sri Lanka acquiring over 65% of the market share. Active in the glass and mirror industry for over three decades, our strategy has been focused on extreme customer satisfaction through providing high quality products at all times. Keeping up with the latest innovations of the industry and introducing new technologies to the glass manufacturing process we have been able to stand above the rest by providing the highest quality products to the market.

SG Industries functions with the best machinery and our European tempered machine is the only European made machine in Sri Lanka which has the ability to provide best quality tempered glass for all kinds of constructions. With a workforce of over 75 highly skilled and experienced staff we are able to meet the market demand for all types of glass and mirror products.

I strongly believe that the knowledge and experience I have gained through different aspects of life has given me the ability to single handedly build up SG Industries to become a significant enterprise in Sri Lanka. My family has given me their immense support at all times which also encouraged me to do better in achieving success in life as well as in business.

The best virtues of a business are honesty, reliability and hard work. SG Industries has proved that we have delivered what we have promised hence the reason for retaining and gaining more satisfied clients throughout the years. We hope to expand our operations and reach higher levels of business functions in the near future and looking forward to maintain the goodwill we have in the Sri Lankan market whilst providing our clients with the highest quality products and superior customer service.
