Z Purlin for Solar or Roof

In terms of corrosion resistance, this Z Purlin for Solar or Roof undergoes hot-dip galvanizing treatment, achieving a zinc coating thickness of 80g/m² or more, providing strong weather resistance. Even in humid and corrosive environments, its service life can exceed 20 years. Furthermore, with its thin wall thickness and high strength, compared to traditional support materials, it can save 30% - 40% of steel, reducing roof loads and being particularly friendly for old building renovation projects.

Since its establishment in 2014 in the Daqiuzhuang Industrial Zone of Tianjin, a major steel hub in China, Shunchen has evolved into a comprehensive industrial chain company encompassing six major business segments, including deep processing of steel products, hot-dip galvanizing production and processing, and photovoltaic new energy development and construction. The company boasts eight subsidiaries, with an annual production capacity exceeding 450,000 tons and an output value nearing 2 billion yuan, demonstrating its substantial strength.

Details

The Z Purlin for Solar or Roof products we produce are cold-formed Z-shaped thin-walled steel sections. As purlin components of the photovoltaic support system, they can firmly support solar panels, guide rails, and fixed components. They can effectively withstand loads such as wind and snow on the roof, as well as their own weight, and evenly transmit the force to the main structure, ensuring stable installation and efficient power generation of the photovoltaic system. For color steel tiles or metal roofs with a large slope, they fully demonstrate their advantages, optimizing space utilization and reducing overall weight.

The Z Purlin for Solar or Roof is unique, with a flange inclination angle ranging from 60° to 75°, significantly enhancing its bending and torsional resistance. It is particularly suitable for roofs with slopes greater than 15°, reducing torque loss and improving system stability. After undergoing hot-dip galvanizing treatment, the zinc coating thickness reaches 80g/m² or more, providing strong weather resistance and a service life of over 20 years in humid and corrosive environments. Moreover, its thin wall thickness and high strength allow for a 30% - 40% reduction in steel usage compared to traditional materials, reducing roof loads and facilitating the renovation of old buildings. It supports continuous lap joints, speeding up construction and reducing on-site welding work.
