The (filter cages) framework is the rib of filter bag and formed through primary welding of special equip-ment. lt is characterized with firm welding, smooth and upright appearance to make the filterbag not damaged, flexible application, easiness in installation and maintenance. Post-surfacetreatment is subject to galvanization or plastic spraying process. The quality of frameworkdirectly influences filter efficiency and service life of filter bag.

They are widely used in cement plants, mining industry, steel plants, power plants, waste incineration systems, and industrial dust collection equipment.
