HVAC (Heating, Ventilation, and Air Conditioning)

In the context of the steel industry, HVAC refers to the galvanized sheet metal and tubular systems used to move air.

The Material: Galvanized steel is the material of choice for HVAC ductwork because it resists mold growth, is fire-resistant, and maintains structural rigidity.

Significance: Modern HVAC systems require pipes and ducts with high "formability" (Lock-Forming Quality or LFQ) so they can be bent into complex shapes without the zinc coating flaking off.
