FRP π Profiles Put Into Full Production, Opening New Possibilities for Lightweight Structural Design
Jiangsu, China — November 2025
Nanjing Spare has started full-scale production of its newly developed FRP π Profiles, strengthening the company’s range of structural composite materials and offering customers a new option for lightweight, corrosion-resistant construction.
The π-shaped profiles are produced through a continuous pultrusion process. With two parallel flanges and a central web, the design provides good stiffness and stability while keeping the overall weight low. This makes the profiles suitable for projects that require strength but also need to reduce installation weight or avoid long-term corrosion problems.
“Our team has been refining the structure and material system of the π profile for some time,” said Spare’s technical director. “The new profiles perform well in demanding environments and require minimal maintenance, which has been welcomed by many of our industrial clients.”
Applications Expanding Across Multiple Industries
Since trial production began, the FRP π Profiles have already been used in several ongoing projects:
Power and Telecom
Used as part of cable support systems, substation structures, and antenna framework components. The non-conductive material provides an added layer of safety in high-voltage areas.
Marine and Offshore
The profiles have shown strong performance in coastal installations, including walkways, protective structures, and equipment platforms exposed to salt spray.
Chemical and Environmental Facilities
Thanks to their resistance to chemicals and moisture, they are being adopted for pipe rack supports, equipment bases, and wastewater treatment structures.
Construction and Infrastructure
Architects and contractors are testing them in roofing systems, façade frames, and shading installations where reduced weight and corrosion resistance are advantageous.
Feedback from customers indicates that the profiles help reduce on-site work time and offer a longer service life compared with certain metal components.
Company Perspective
According to the company’s general manager, the FRP π Profile series is part of a broader plan to expand the composite structural product line.
“We are seeing more customers looking for materials that deliver predictable performance without the maintenance burden of steel in harsh environments,” she said. “The π profile is one of several products we are bringing forward to meet that shift. We will continue investing in production, testing, and engineering support to provide reliable solutions for different industries.”
