Bottom Rolling Bifold Door

Here at Ezi Aluminium Systems, we have developed a stylish Bottom Rolling Bifold Door system to accommodate the evolving architectural market. Free of fixed panels, mullions, and posts, provides an unobstructed panoramic opening to the outdoors encouraging Alfresco living. The unique incorporation of quality sill covers, guards, and drainage holes, minimises maintenance delivering consistent performance. Bottom Rolling systems allow the weight of the door to be transferred away from the top of the opening, eliminating the need for a strong, and often restricting upper beam permitting additional design space.
