Folding Doors

Folding doors, also known as bi-fold doors, are designed to create a seamless connection between indoor and outdoor spaces. Composed of multiple panels connected by hinges, these doors fold neatly to one or both sides, allowing for a wide and unobstructed opening.

At Delanshini, we specialize in aluminum folding doors that combine elegant design, precision engineering, and exceptional performance. Perfect for patios, balconies, offices, and commercial spaces, our folding doors offer flexibility, functionality, and aesthetic appeal in one smart system.
