Application of Galvanized Pipes in Photovoltaic (PV) Projects

From large-scale ground-mounted power plants to commercial and industrial rooftops, galvanized pipes—primarily hot-dip galvanized steel pipes—serve as the primary structural components for supporting photovoltaic modules. Recent tender data indicates that the demand for PV mounting structures is heavily concentrated on galvanized round steel pipes and cold-formed steel sections.

Specifically, galvanized pipes are utilized across several critical components of PV mounting systems:

Uprights and Beams: Serving as the primary load-bearing and force-transmitting elements of the mounting structure, these typically consist of round pipes (e.g., specifications such as φ140×3.5 mm).

Inclined Beams, Braces, and Secondary Beams: These generally utilize hot-dip galvanized, cold-formed thin-walled steel sections with thicknesses ranging from 1.6 mm to 4.5 mm, chosen for their lightweight and cost-effective properties.

Drive Shafts for Tracking Systems: Used in solar tracking mounts—which adjust to follow the sun’s position—these applications demand higher precision and greater strength from the piping.

Main Framework for PV Carports: Serving as the primary structural support for these long-span installations.

Helical Steel Piles: Used for foundation anchoring in ground-mounted power plants; for example, galvanized helical piles with specifications such as 76×4 mm and a length of 1.8 meters.
