Top Hung Sliding Doors

Cronax Industrial Top Hung Sliding Doors are engineered for heavy-duty performance, durability, and space efficiency in demanding industrial environments. Designed with a top-hung mechanism, the entire door weight is supported from the top track, ensuring smooth, noiseless, and low-maintenance operation without interference from floor obstructions. Made from high-quality steel or aluminium panels, these doors offer excellent resistance to impact, dust, and harsh weather.

Their sturdy construction provides long service life and enhanced security, making them ideal for warehouses, factories, aircraft hangars, and large industrial units. Design allows for wide opening spans while keeping the floor area free, ensuring unhindered movement of forklifts, trucks, and heavy machinery. Available in manual or motorized operation, Cronax sliding doors can be customized with insulation, vision panels, or automation systems to meet specific requirements.
