U-Shaped Hot-Dip Galvanized Steel Rail for Solar Mounting Systems

The U-shaped hot-dip galvanized steel rail is a critical structural component in solar PV mounting systems. Engineered for multi-functional use, this rail serves as a pillar, beam, and rail within the racking system. Its uniformly spaced perforations along the U-shaped base not only enhance visual appeal but also optimize structural performance, allowing for flexible assembly and robust load-bearing capacity.

Manufactured primarily from Q235, Q345, or other mild carbon steels, this U rail offers excellent mechanical strength and ductility. For enhanced durability, the rail undergoes hot-dip galvanization (HDG), a process that immerses the steel in molten zinc to create a corrosion-resistant, maintenance-free protective layer.

With customizable lengths and pre-designed connection compatibility, this rail can be easily adapted to various rooftop or ground-mount PV applications, making it an ideal solution for long-lasting solar infrastructure.

.FAQ

• 

  Q1: What materials are available for the U-shaped rail?

  A: Our standard U-shaped rails are made from Q235 or Q345 carbon steel, both of which offer excellent strength and ductility. Upon request, we can also provide stainless steel versions for highly corrosive environments.

• 

  Q2: What is the surface treatment applied to the rail?

  A: The rails are treated using the Hot-Dip Galvanization (HDG) process, which provides a thick zinc coating for long-term corrosion resistance. This treatment complies with ISO 1461 standards or equivalent.

• 

  Q3: Can the rail be customized in terms of length and hole pattern?

  A: Yes, we offer customizable lengths (typically 2.4m, 3.0m, or as required) and pre-punched hole designs according to your structural needs or connector compatibility.

• 

  Q4: What thickness options are available for the rail?

  A: Standard thicknesses include 2.0mm, 2.5mm, and 3.0mm, but we can adjust according to your project specifications or load requirements.

• 

  Q5: What’s the typical application of this rail?

  A: This U-shaped rail is used in rooftop and ground-mounted PV systems, serving as a support beam, alignment rail, and structural base for the solar panels.
