What is a Galvanized Bag Cage?
A Galvanized Bag Cage is a Fine precision-engineered filter support cage That is used to hold and protect dust filter bags inside baghouse dust collectors.
It is Made from high-quality carbon steel and coated with a galvanized zinc layer that it prevents rust, corrosion and premature wear in demanding industrial environments.
Main Features of Galvanized Bag Cage Material
Material: in here we used High-quality galvanized steel with anti-corrosion coating.
Corrosion Resistance: from resisting from corrosion there used Superior zinc coating ensures durability against moisture and chemical exposure.
High Strength: The Rigid structure designed to maintain shape under high-pressure conditions.
Smooth Surface Treatment: the surfaces Minimizes wear and tear on filter bags.
Custom Design Available: It is Manufactured to customer specifications including size, coating thickness and connection styles.
