Span is 70m , it is one of the biggest trestles.

BIPV (Building Integrated Photovoltaic)  is a technology that integrates solar power generation products into buildings. It not only has a photovoltaic power generation project but also can meet the basic functional requirements of buildings. Advantages of BIPV Roof： Replace traditional rooftops for power generation for self-use and surplus power to be fed into the grid Extend the service life of the building roof by up to 30 years. High return on investment and continuous stable earnings The government’s relevant policies strongly encourage energy conservation and emission reduction. Can enter the list of low-carbon and green building enterprises Advantages of BIPV System： Compared with the BAPV distributed power station where components are laid on the color steel plate roof, the BIPV integrated photovoltaic roof can be designed to cover the entire roof surface. The entire photovoltaic array has a higher power, higher power generation, and lower overall cost.

BAVP (Building Attached PV), is a technology that installs a solar photovoltaic power generation system on the roof of an existing building. It not only has a photovoltaic power generation project but can also preserve the original building structure to the greatest extent. Advantages of BAPV Roof： There is no need to change the original roof structure. It is convenient to install and has a strong load-bearing capacity. The investment cost of some photovoltaic components is low. It has stronger heat preservation and insulation capabilities.

The single span of this trestle project reaches 80 meters, which is the largest span among similar trestles in China. It has a double-belt and double-layer grid truss structure.

This project is the steel structure main workshop of the coal preparation plant, which is a multi-storey frame structure and the world’s largest coking coal washing system, with a construction area of 46,000 square meters.
