Bars, Rods & Custom Profiles
Innovative alternatives to current technical needs
Due to the high versatility of fiberglass, it is often chosen as an alternative in the most challenging applications. As a result, it is not a surprise that fiberglass is rapidly replacing traditional materials such as steel, aluminum and other metal-based as well as timber and thermoplastic cross-sectional products in many applications.
Pultrusion Technique has been pultruding a variety of fiberglass profiles since 1982, with an expertise in manufacturing products with ultra-high mechanical properties and environmental resistance.
Rather than the custom section that matches the need of our clients, our quality control assurance program ensures products with superior dimensional stability and consistent strength.
We offer options for the laminating resin that binds the composite together such as polyester and vinylester, and we use unique techniques and in-house developed recipes to improve the final product in terms of surface appearance, and also mechanical, chemical, and weather resistance. Manufacturing of all custom profiles can benefit from a variety of substances such as pigments to impart color and accelerators to cure the laminating resin.
Moreover, decades of experience, research and developments in pultrusion, combined with our long-term supplier-client relationships through supplying world-class products for our clients in mining, petroleum and electricity sectors has helped us in the followings:
- providing higher safety factors by exceeding the ultimate load requirement specified by the clients
- enhancing specific rating in terms of fire retardancy
- improving UV resistance of the products
- exceeding industry standards in terms of corrosion resistance
- achieving consistent color throughout
Our research and development team also collaborates for prototyping needs of industries, universities, and research centers, be it small-scale productions for demonstration samples and trials or large-scale productions.
We serve a variety of economic sectors where composite materials continue to offer innovative alternatives to current technical needs. We are able to design and manufacture a customized solution that will meet your needs, regardless of the industry, be it architecture, infrastructure, pulp and paper, etc.
Composites have a low coefficient of expansion, low thermal conductivity and require little maintenance. They are lightweight, long-lasting and offer high resistance to corrosion and weatherability. Their dimensional stability, flexural, dielectric and tensile strengths, and high strength-to-weight ratio make them better than aluminum, vinyl, wood or steel.
Our manufacturing processes are among the best. We use high quality reinforcing fibers, structural adhesives and resins, which make polymerization highly effective and ecologically aware, and meet the most demanding chemical, flame retardant, electrical and environmental conditions.
Our products are well known for their quality and reliability. As an example, 70% to 75% of the weight of the bars is high quality fiberglass roving.
Experience, technology, design and resin matrices are what set us apart. We manufacture products with very accurate dimensional tolerances, high strength-to-weight ratio, improved transverse and shock resistance, and superior mechanical properties.
TAILORED TO YOUR SPECIFIC NEEDS
A multitude of Applications
Regardless of your requirements, Pultrusion Technique has the solution. Our professionals use their expertise and technical skills to create and implement practical and strategic solutions to generate growth and value with our client companies.
We well understand that different clients need pultruded products in different custom-made forms and shapes. The design freedom of pultrusion is one of the many advantages of fiberglass pultrusion process, and a major part of the reason for its success in growing as a popular construction material.
With our custom designed and frequently improved pultrusion line, we are capable of manufacturing any custom shape, be it solid or hollow, open or close thin wall sections such as rods, straps, tubes, channels, tees, and any other custom profile. Our services can also include high quality post-processing such as custom-pattern drilling, sanding and grinding.
