Following extensive research and development CAIS is now in the enviable position of offering the highest quality product available for the gate market. We have worked with a renowned University looking at the way the load is transfered throughout the wheels, bearings and carriages whilst under stress of a moving gate. The results surprised and inspired us to re invent our product, to become more accurate and search intensivley for a steel supplier that can match our ambitions. We searched for a galvanised steel that doesnt crack under rolling, we searched for steel of the correct tolerances and chemical composition. We found all this and more and created something very impressive.

CAIS also invested, heavily, in what is the heart of our company, a brand new roll forming line. With uniquely, 18 large precision formed rollers that allows minute differences to be made until the rolling is perfectly straight and accurate to our own exact standards.
