Beaded Steel: Sheet steel that has been seamed with a perforation to make bending/folding into L-duct easier.

Galvanized: Zinc-coated by the hot-dip process (galvanized coating: Coating of virtually pure zinc on carbon steel substrate). Material is leveled to ensure non-fluting quality.

Common Coating Weights Available: G30, G40, G60, G90

Benefits:

• Zinc extends the life cycle of steel and enhances corrosion resistance.
• Zinc reduces maintenance costs and can be recycled indefinitely
