China Fiberglass Base Manufacturer, Supplier, Factory

The Dongshuimen Bridge in Chongqing was completed in 2014, and its most advanced fiberglass bridge deck was provided by Spare. The bridge deck adopts Spare's innovative hollow mesh technology, which has outstanding advantages. This advanced fiberglass solution not only ensures excellent durability, but also simplifies the construction process. Due to the use of Spare's fiberglass material, the bridge deck can be seamlessly integrated and asphalt can be directly laid after installation, greatly reducing construction time and cost.

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.

With the accelerated development of the new energy vehicle industry, power battery safety and light-weighting have become core R&D directions for the sector. Recently, FRP (fibre-reinforced composite materials) has achieved large-scale application in electric vehicle battery pack side panels due to its multi-dimensional performance advantages. This provides critical support for power battery system safety protection and overall vehicle energy efficiency enhancement, attracting widespread industry attention.

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.

The performance core of glass fiber pultruded profiles is determined by the resin matrix. Three mainstream materials, namely vinyl ester, isophthalic polyester and ordinary epoxy, have their own focuses in terms of mechanical strength, corrosion and heat resistance, processing cost and other dimensions, and their applicable scenarios are significantly different.

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.
