What Are EPAI Aluminum Folding Doors?
EPAI aluminum folding doors — also known as bi-fold or accordion doors — are multi-panel door systems where all panels fold and stack accordion-style to one or both sides of the opening. Unlike sliding doors, folding doors provide a completely unobstructed opening with no fixed panels, creating a seamless indoor-outdoor connection across the full width of the opening.
Our folding doors are manufactured from high-grade 6063-T5 aluminum alloy with optional thermal break profiles. Available in two-panel to eight-panel configurations with inward or outward folding, double or triple glazing, top-hung or bottom-rolling track systems, and hardware in chrome, brushed nickel, matte black, and anodized finishes.
With over 15 years of manufacturing expertise, EPAI delivers folding door systems trusted by architects, developers, and homeowners across 100+ countries for luxury residential patios, living rooms, commercial offices, hotel lobbies, and large-scale partition applications.
