Moveable corner post bifold doors from BM Bi-Folding Doors are engineered for high-impact architectural projects where a fully open 90° corner is required. The system combines two bifold sets that meet at the corner, locking together securely when closed and folding away completely when opened — removing the need for a fixed support post. This design delivers uninterrupted panoramic openings, ideal for contemporary extensions, orangeries, and premium residential or commercial builds seeking a true “glass box” effect.

Each corner system is manufactured to precise site dimensions and assembled using Smart Systems aluminium profiles for structural integrity, weather performance, and smooth operation. Backed by BM’s technical expertise, these systems are built for trade professionals who need accuracy, reliability, and a striking finish that sets projects apart.
