Sterling Foundry is proud to be the sole UK distributor of the full range of CAIS hardware. Since their inception in 1992 CAIS have been dedicated to making the best and highest quality cantilever and sliding gate hardware on the market.

25 Years of Innovation

It’s only after 25 years that the culmination of this experience has produced the best production line for cantilever hardware in the world. 

  • This can be seen with the dedication and passion of the workforce. 
  • This can be seen in the packaging. 
  • This can be seen in the care and attention to the smallest details. 

As it’s this detail on hardware that can make all the difference in the lifespan of the product and the electric motors that power them.

Following extensive research and development, CAIS is now in the enviable position of offering the highest quality product available for the gate market.

After extensive research, the results surprised and inspired them to reinvent their product, to become more accurate and search intensively for a steel supplier that can match their ambitions. They searched for galvanised steel that doesn’t crack under rolling, they searched for steel of the correct tolerances and chemical composition.

We found all this and more with our German Supplier WUPPERMANN and created something very impressive. CAIS also invested heavily in what is the heart of their company, a brand new roll forming line.

The Roll Forming line is unique in its precision and accuracy, with uniquely, 18 large precision formed rollers that allow minute differences to be made until the rolling is perfectly straight and accurate to their exact standards.

State Of The Art Roll Forming Line

Eighteen Roll Formers – The best in the industry to remove the inset “memory” of the metal. Built-in flying hole punch – Punches a hole in the rail exactly every 400 mm.

Slow rolling – This means no heat during the production keeping the material where it is rolled with no “relaxation” of the product after.

Steel Strip

Steel Stripe must only be the best, which is why world-renowned Wupperman Steel is the only supplier capable of the exacting standards they require. Galvanised stripe of exacting standards means that you can bolt our product only after you’ve galvanised your gate. So even if your gate is slightly bent. The rail won’t be.


Engineering Excellence Carriages

Carriages – Centre holes are milled not lasered. Only high strength certificated precision tool steel is used. Wheels are riveted into position with just exactly the right amount of pressure. This gives our carriage a trademark smoothness once the load is applied.
