At GCER, we stand out for our excellence in the design and manufacture of GRP ducts and GRP Chimneys , innovative solutions recognized for their exceptional strength, proven durability and unrivalled chemical resistance.
These products meet the most stringent industry standards, ensuring long-term durability and optimum performance in the most demanding industrial environments.
Our commitment to continuous innovation and our personalized approach guarantee our customers uncompromising reliability and total satisfaction for their critical industrial needs.
The sizing of our ducts and chimneys is based on several internationally recognized standards such as EN 13121-3, BS 4995, AD Merkblatt, ASME X, and ASMERTP-1. These norms guarantee the reliability and safety of our products, ensuring that they meet our customers' most stringent requirements.
The design process begins with a detailed preliminary drawing. This drawing includes dimensional measurements, design and operating pressure criteria, as well as maximum expected and actual operating temperatures. This precise data ensures an optimal and safe design.
At GCER, we use advanced manufacturing techniques to produce GRP liners and chimneys.
These techniques ensure not only the robustness and durability of our products, but also their adaptability to the specific needs of each project.
This technique involves winding resin-impregnated fiberglass filaments around a mandrel to create strong, lightweight cylindrical structures.
A manual process in which layers of fiberglass are placed in a mold and impregnated with resin. This process is ideal for complex shapes and small production runs.
A technique in which chopped glass fibers and resin are sprayed simultaneously onto a mold, offering a fast and efficient method for producing composite parts.
To complement our duct and chimney solutions, we offer a range of accessories that enhance the functionality and ease of installation of our products. Available accessories include :
Devices for securing chimneys and ducts in place.
Entry and exit points for fluid lines.
Sturdy lifting points to facilitate transport and installation.
Openings for access to the inside of chimneys and ducts, available in various shapes (rectangular, circular, etc.).
Support structures to hold ducts and chimneys in position and ensure stable installation.
Coating options to protect the surface and enhance aesthetics.
GRP ducts and chimneys offer a host of advantages that make them ideal for demanding industrial applications. Here are the main benefits :
Our products are specifically formulated to effectively resist corrosive fumes containing high concentrations of HCL, H2SO4, and other aggressive chemical agents, ensuring exceptional durability even under extreme conditions.
Due to the exceptional durability of composite materials, ducts and chimneys require little or no regular maintenance, minimizing maintenance costs throughout their operational life cycle.
Combining high mechanical strength with relatively low weight, our products are easy to handle, assemble and install on site, reducing handling costs.
Our products offer exceptional resistance to chemicals and severe atmospheric conditions, guaranteeing long life and consistent reliability in harsh industrial environments.
Composite material is an excellent thermal insulator, reducing heat loss and optimizing the energy efficiency of the industrial systems where they are installed.
Our products are designed to maintain their structural integrity and performance at elevated temperatures, ensuring continued operational reliability without significant deformation or degradation.
With a low coefficient of linear expansion, ducts and chimneys retain their shape and dimensions even in the event of major thermal variations, guaranteeing long-term operational stability.
GRP (Glass Reinforced Polyester) is a composite material combining polyester resin and glass fibers. This combination gives it high mechanical strength, excellent durability, and remarkable chemical resistance.
GRP (Glass Reinforced Polyester) is a composite material offering an exceptional combination of lightness, mechanical strength, and durability. It is distinguished by its high resistance to corrosion, chemicals, and extreme environmental conditions, making it ideal for a wide range of industrial applications. In addition, its design flexibility allows for the manufacture of custom structures, optimizing the performance and longevity of equipment.
GRP (Glass Reinforced Polyester) cannot be recycled in the same way as traditional plastics. Due to its composite composition—a polymer matrix reinforced with glass fibers—conventional mechanical recycling is difficult. However, there are specialized processes for recovering end-of-life materials, including energy recovery or grinding techniques and reuse in secondary applications (fillers, construction materials, etc.). In addition, research is underway to develop more sustainable recycling methods for composites. GCER remains attentive to these technological developments in order to integrate environmentally friendly solutions into its processes.

GCER operates in various sectors, including : • Water and water desalination • Wastewater • Chemicals • Agri-food • Energy • Mining • Oil • Environment • Industrial processes
GCER specializes in : • Composite materials (GRP) • Thermoplastics such as HDPE, PVC, PPH, PVDF, PVC-C, ECTFE, and PFA • Metal construction
To find out if thermoplastic or GRP equipment has reached the end of its service life, check for : • Cracks or deformations. • Loss of resistance to stress. • Leaks or damaged seals. • Reduced performance after testing or inspections. It is important to follow the manufacturer's recommendations and carry out regular checks.
GRP (Glass Reinforced Polyester) is generally more expensive than thermoplastics. This difference is due to a more complex manufacturing process and the use of reinforced materials. However, GRP offers better mechanical and chemical resistance, making it ideal for demanding applications.
