In the first half of 2026, newly installed wind power and photovoltaic capacity in China continued to rise. New energy equipment imposes higher standards on fasteners for fatigue resistance, corrosion resistance and preload retention. Demand for expansion bolts, channel steel, connecting bolts and embedded components used in photovoltaic supports continues to increase; orders for high-strength bolts and mechanical anchors supporting wind power equipment grow steadily.
Unlike ordinary civilian fasteners, new energy applications operate long-term in outdoor conditions with sand, wind, humidity and large day-night temperature differences, imposing stringent requirements on material, heat treatment, hot-dip galvanizing and Dacromet surface treatment.
In the building anchoring sector, photovoltaic curtain walls and BIPV (Building Integrated Photovoltaics) projects are increasing, and demand for curtain wall accessories such as aluminum alloy hangers, back bolts, chemical anchors and channel steel clamps is released simultaneously. Many fastener source factories develop customized products for new energy working conditions, optimizing thread structure and anti-corrosion processes to adapt to large-scale new energy engineering projects.
