The FRP cooling tower at the Shanghai Laogang Renewable Energy Utilization Center Phase II Project, designed by SPX Company, incorporates SPARE company's FRP materials for enhanced performance. With a mechanical ventilation mist elimination design, it efficiently handles 4000m3/h of cooling water per tower, totaling 40000m3/h. The tower group, arranged in a single line on the southwest side, consists of two sets of five towers each, with a shared circulating water pump room nearby. Each tower, utilizing SPARE's pultruded FRP frame structure, stands at 21.2 meters tall and 21.1 meters wide, offering both strength and lightweight characteristics, with over 400 tons of FRP pultruded profiles used in total.

The corridor bridge at Tsinghua University Civil Engineering Department uses GFRP panels as permanent formwork for its deck. These panels are chosen for their light weight, ease of construction, and durability. They are secured to the secondary girders with bolts and can be manually adjusted on-site without cranes. Edges are sealed to prevent concrete spillage during pouring. Once set up, concrete is poured over the positioned GFRP bars. Post-installation, the panels require minimal anti-corrosion treatment.

Glass fiber-reinforced plastic (GFRP) is a highly durable composite extensively utilized in aircraft components and wind turbine blades. However, its robust characteristics pose significant challenges for disposal, often leading to landfill burial after its useful life.

Recently, a new type of building material - FRP sandwich panels with excellent thermal insulation performance, in the construction industry has attracted widespread attention, known as the industry as "thermal insulation magic weapon".

In November 2025, Nanjing Spare launched a new anti-slip FRP pultruded grating. This product innovatively adopts an anti-slip serrated pattern design, and its anti-slip coefficient in wet environments is increased by more than 40% compared with ordinary gratings, completely solving the pain point of easy slipping on the smooth surface of traditional gratings.

With the increasing demand for high-performance materials in the construction industry, FRP (Fiberglass Reinforced Plastics) angle steel, with glass fiber as the reinforcing material, combines high strength, corrosion resistance and good processability. Compared with traditional metal angle steel, it is lighter and more corrosion-resistant, can be used for a long time in harsh environments, greatly reduces maintenance costs, and becomes an ideal alternative to traditional materials, promoting the innovation of construction technology.
