A Key Difference
WIS (Williams Interlock System) is one of the innovations that set Williams products apart. Our aluminum balusters are designed without any assembly screws, making them far more resistant to the harsh climate variations of our region. This unique technique ensures superior durability and aesthetics, perfectly suited to all environments.

Unique Technique
The Williams family revolutionized railing manufacturing by developing an innovative machine that assembles components without using screws. This method significantly increases the efficiency of our production process, optimizing both speed and manufacturing quality in our factory.
Optimal Strength
Williams railings provide superior resistance to freeze–thaw cycles compared to all other screw-assembled products. This enhanced sturdiness ensures exceptional longevity and durability in all weather conditions.
Preassembled Products
Williams railings are preassembled at our factory in St-Alphonse-de-Granby, making installation significantly easier for you. This innovation eliminates the usual complexity of assembly and greatly reduces installation time, allowing you to complete your project quickly and efficiently—without compromising on quality or durability.
Williams, a Family Institution
