Metallic tower packing is usually made of stainless steel,carbon steel,aluminum and other metals.With the merit of large specific surface area,little resistance,low pressure drop,light weight,heat and cold resistance and long lifetime,it has been widely used in the packing tower in the fields of petro-chemistry,fertilizer,chemical engerineering,environment protection,pharmacy,and sugar production.There are two kinds of metallic packing,metallic standare structured packing,and metallic random heaping packing.

Metallic standard structured packing
Metallic standard structured packing can be divided into, gill net ripple packing, pass place ripple packing, silk screen ripple packing and mesh plate ripple packing.
