About FIT
F.I.T. Industrial Co., Ltd. (FIT) is Taiwan's first — and still only — manufacturer that produces both fiberglass plied yarn and PTFE architectural membrane in-house. We opened our doors in Chiayi County in 2003, and by the end of that same year we were already shipping yarn overseas. In 2020, the Serge Ferrari Group acquired a 55% equity stake in FIT, and today our membranes and yarns reach customers across the United States, Europe, South Korea, Japan, China, Mexico, Thailand, India, and the Middle East.
Three things worth knowing before you read on: how a yarn mill in rural Chiayi became Taiwan's only self-manufactured PTFE membrane producer, what changed after Serge Ferrari came on board, and the questions engineers and buyers ask us most. Jump to any section below, or keep scrolling.
Company History: From Yarn Mill to Taiwan's Only PTFE Membrane Manufacturer
We didn't start out making PTFE membrane. For the first five years, FIT was strictly a fiberglass yarn shop — plying yarn to spec, batch after batch, for customers who cared more about consistency than a sales pitch. That's still the mindset behind our three core values: Faith, Innovation, and Trust. Not slogans on a wall. When you're twisting glass fiber into hybrid yarns, there's no room to guess at compatibility between materials. Everything gets tested before it ships. The real pivot came in 2008, when we set up our Tensile Membrane Structure Division and started pushing our yarn expertise upstream into PTFE coating.
- 2003
FIT was founded in Taibao City, Chiayi County, as Taiwan's first manufacturer of fiberglass plied and twisted yarn. We began exporting before the year was even out.
- 2008
We established our Tensile Membrane Structure Division to pursue vertical integration, combining our yarn expertise with newly developed PTFE coating technology.
- 2009
FIT achieved ISO 9001 certification and has maintained it continuously, keeping our process and quality controls aligned with the current standard.
- 2014
We became Taiwan's sole manufacturer of high-performance PTFE architectural membrane. Our MIT membranes were exported to Germany, Singapore, the Philippines, South Korea, China, Turkey, and the Middle East.
- 2020
The Serge Ferrari Group acquired a 55% equity stake in FIT, making us a core member of the Group and opening the door to a much larger international customer base.
End-to-End Service, Managed In-House
Most competitors sell you the membrane and walk away. We don't. Every project we take on runs through the same four-stage team, in-house, start to finish:
- Sales & Consultation: scoping the project and pinning down what you actually need before anything gets ordered
- Design & Engineering: architectural drafting plus structural mechanics analysis
- Fabrication & Logistics: precision membrane processing, packaging, and international shipping
- Steel Construction: on-site structural assembly and tensioned installation, handled by our own crew
Joint Venture with the Serge Ferrari Group
Serge Ferrari Group was founded in France in 1973 and has grown into a world leader in flexible composite membrane design and manufacturing, with operations across more than 80 countries. In 2020, the Group recognized the potential of our high-performance PTFE membranes and acquired a 55% equity stake in FIT — making them our largest shareholder.
This isn't a passive investment. It's built around a working split: front-end global sales and distribution, back-end lean manufacturing right here in Chiayi.

Frequently Asked Questions
What does FIT actually manufacture?
We make two core product lines: fiberglass plied yarn, and self-produced PTFE architectural membrane, including our T-Series shading membrane, M-Series facade mesh, and S-Series interior acoustic membrane. On top of that, we run the entire tensile membrane structure process in-house, from raw material through on-site installation.
How is FIT different from a trading company or distributor?
The short answer: we manufacture, they resell. Most suppliers in this space import membrane from overseas and pass it along. Every step from yarn plying to PTFE coating happens at our own Chiayi plant, so lead times, spec changes, and quality checks don't have to wait on a reply from some other country's factory.
What's FIT's relationship with the Serge Ferrari Group?
Serge Ferrari Group acquired a 55% equity stake in FIT in 2020, making them our largest shareholder. We still run our own Chiayi manufacturing base and technical team, focused on R&D and production. Serge Ferrari, in turn, brings us into projects through their global distribution network.
Is FIT really the only company in Taiwan producing PTFE architectural membrane?
Yes. FIT has been Taiwan's sole manufacturer of PTFE architectural membrane since 2014, and we were also the first company in Taiwan to produce fiberglass plied yarn. That combination — fiber material through membrane coating, plus in-house steel fabrication and tensile structure engineering — is what lets us offer a genuinely vertically integrated service.
Which countries does FIT currently export to?
Our yarn and membrane products currently reach the United States, Europe, South Korea, Japan, China, Mexico, Thailand, India, and the Middle East. Our MIT PTFE membrane specifically has a track record in Germany, Singapore, the Philippines, South Korea, China, Turkey, and the Middle East, going back to our first export shipments in 2014.
