Fibrosan Builds Michigan GFRP Plant to Localize North American Supply

Updated on September 07, 2026 • 6 min read

Turkish fiberglass supplier Fibrosan has broken ground on a new manufacturing facility in Cassopolis, Michigan, establishing a domestic production base closer to its North American customers in the recreational vehicle, automotive and construction industries.

Construction began in early July 2026, with the first phase expected to become operational in March 2027.

Phase 1 is expected to create 35 jobs in the region.

More significantly for Fibrosan’s longer-term manufacturing strategy, the company is already planning a Phase 2 expansion that could approximately triple the facility’s production capacity.

The investment represents more than a geographical expansion for the İzmir-based manufacturer. It moves Fibrosan from serving North American customers across an international supply chain toward producing GFRP materials inside one of its major end-use markets.

Michigan Plant Brings GFRP Production Closer to Customers

Fibrosan supplies glass fiber-reinforced polymer materials for applications across the RV, automotive and construction sectors.

Locating production in Michigan gives the company closer access to customers and distribution partners in North America.

For composite materials suppliers, distance between manufacturing and customers affects more than transportation costs.

Lead times, inventory requirements, production scheduling and the ability to respond to changes in customer demand can all be influenced by where material is produced.

Fibrosan expects the Cassopolis facility to improve the speed, reliability and flexibility with which it serves the region.

Domestic manufacturing can also reduce some exposure to international freight disruptions and long-distance logistics.

However, this should not be interpreted as complete supply-chain independence.

The resilience of the Michigan operation will still depend on where Fibrosan sources its glass fiber, resin systems, additives and other manufacturing inputs.

Phase 2 Could Triple Production Capacity

Fibrosan is approaching the project in stages.

The first phase establishes the company’s initial manufacturing operation in Cassopolis and is expected to create 35 jobs.

A planned second phase would substantially increase the site’s manufacturing footprint, potentially tripling production capacity.

That makes the expansion particularly relevant from an industry perspective.

Rather than building only a small regional finishing or distribution operation, Fibrosan appears to be creating a manufacturing platform that can be expanded as North American demand develops.

The exact production capacity, product mix and timing of Phase 2 have not been disclosed in the supplied information.

Those details will ultimately determine the scale of the plant’s role within Fibrosan’s global manufacturing network.

RV Market Provides a Natural Location Advantage

The location is also notable because Fibrosan serves the recreational vehicle sector.

Northern Indiana and southwestern Michigan sit within one of North America’s most concentrated RV manufacturing regions.

For a composite materials supplier, proximity to this manufacturing base can shorten the physical distance between material production and OEM consumption.

That can become particularly useful when customers require changes to material specifications, production schedules or product configurations.

The same facility will also support Fibrosan’s automotive and construction customers.

These sectors have different technical requirements, but all can benefit from a regional source of GFRP materials where shorter supply chains and closer technical communication are valuable.

Local Manufacturing Could Also Shorten the R&D Loop

Fibrosan identifies collaborative research and development as another reason for establishing North American production.

With technical and manufacturing teams closer to distributors and OEM customers, the company expects to respond more quickly to feedback, evolving requirements and product-development programs.

This can be important in composites because material development is rarely isolated from the downstream manufacturing process.

A GFRP product must ultimately work within a customer’s forming, laminating, bonding, finishing or assembly process.

When material behavior needs adjustment, development can involve repeated interaction between the material supplier and processor.

Reducing the geographical separation between those teams could shorten that feedback loop.

Whether the Cassopolis operation will contain dedicated laboratory or application-development capabilities has not been detailed in the information released so far.

Fibrosan Builds on More Than 20 Years of Development

Fibrosan CEO Erim Yucel describes the Michigan investment as the result of more than two decades of company development.

Over that period, Fibrosan says it has invested in manufacturing capacity, technology, employees and customer relationships.

The Cassopolis project moves that development into a new stage by establishing physical production capacity inside the North American market.

For a multinational composites supplier, this transition can be strategically significant.

Exporting material into a market and manufacturing material within that market involve different capital requirements, supply-chain structures and customer relationships.

The Michigan investment therefore indicates a longer-term commitment rather than simply an expansion of export sales.

Professor’s Analysis: Localization Is Becoming Part of Composite Material Strategy

The Fibrosan investment illustrates a broader change occurring across composite supply chains.

For years, globalization encouraged manufacturers to optimize production around centralized plants and international logistics.

Recent supply-chain disruptions have exposed some of the limitations of that model.

Composite materials can be particularly sensitive to this issue because downstream manufacturers depend on consistent specifications, predictable deliveries and qualified material systems.

Changing supplier or formulation is not always straightforward when a material has already been integrated into an OEM’s production process.

That makes regional manufacturing capacity increasingly valuable as part of supply assurance.

Fibrosan’s Michigan strategy combines three functions that are worth watching:

production localization, customer proximity and application-development proximity.

The first can shorten logistics.

The second can improve responsiveness.

The third can potentially accelerate product iteration between material supplier and OEM.

But localization should not be confused with complete vertical integration.

If key fibers, resins or chemicals continue to cross international borders, some upstream exposure remains.

The real measure of supply-chain resilience will therefore depend on how much of Fibrosan’s material ecosystem can eventually be sourced and processed regionally.

Phase 2 Will Reveal the Scale of Fibrosan’s U.S. Ambition

The March 2027 startup will mark the beginning rather than the completion of Fibrosan’s North American manufacturing strategy.

Phase 1 establishes the production base.

Phase 2 could determine how strategically important Cassopolis becomes within the company’s overall manufacturing network.

If capacity is ultimately tripled as planned, the facility could move from an initial localization project toward a substantially larger regional supply operation.

For North American composites customers, the significance is straightforward.

Fibrosan is no longer positioning the region simply as an export destination.

It is putting manufacturing capacity closer to the industries consuming its GFRP materials.

In a composites market where material performance remains critical but lead time, supply stability and technical responsiveness increasingly influence purchasing decisions, that geographical shift may matter almost as much as the products coming off the production line.
