Products&Technology
Yung Ching offers fire-rated windows made of steel and thermally broken aluminum. Features include optional thermal insulation and opening styles such as fixed and operable. Operable fire-rated windows can be fitted with automatic closing devices that automatically close the window sashes in the event of a fire. They can meet the extreme fire protection requirements of special areas, such as observation windows in subway control rooms. Steel fixed thermal fire-rated windows use steel frames and meet the requirements for fire resistance, integrity, and internal insulation for a specified period. They are used in high-rise residential buildings, public buildings, and industrial or civil buildings requiring fire compartmentation.
Fire-resistant Rolling Shutter
YonKing fire-resistant rolling shutters are divided into steel composite fire-resistant rolling shutters and inorganic fabric fire-resistant rolling shutters according to their materials. YonKing steel composite fire-resistant rolling shutters use steel materials for the curtain plates, guides, base plates, lintels, boxes, etc., and are equipped with a rolling door machine and control box to form a fire-resistant rolling shutter that meets the requirements of fire resistance integrity. YonKing inorganic fabric-based fire-resistant rolling shutters use 3cm thick fire-proof treated aluminum silicate fiber cloth as the curtain surface, with a reinforced steel strip in the middle, making it a soft and lightweight rolling shutter that achieves the same fire resistance requirements as steel fire-resistant rolling shutters. This product has a lighter curtain surface, smooth operation, and low noise: it is widely used in fire compartment separation of buildings such as offices, supermarkets, shopping malls, exhibition halls, underground garages, and entertainment venues.
