Quality You Can Swear By
Delta Laminates go through some of the most stringent quality tests in the industry. Before a Delta product becomes a part of your home or office space it goes through thorough tests for heat resistance, crack-resistance, stain-resistance and scratch test all at an ISI certified laboratory equipped with specialised Q&A machines from Germany and the USA.
As far as Delta products are concerned, ‘ tested ok’ would be an understatement. We test a product until we know for sure that it’s more than just ok. It has to be great. It has to last. Quality is what we built our company upon. And it’s what every Royale product is made of.
