WHEN YOU SET OUT TO CREATE THE PERFECT OPERATOR

WHY SIGMA?

We started on journey to revolutionize the automatic door opener business. We did that by defying an age old adage in the building industry that you can have EITHER Price, Quality OR Delivery but not all three. But we beleived we could break through the barriers that prevented enjoying the benefits of all three and created a product that delivered high reliability, manufacturing done in our own facilities here in North America and delivered at a price which was one of the most competative in the industry.
