Composite (laminated plastic) profiles are well known to the wide public as fibreglass (or carbon) bars or tubes. Nevertheless, our company\u2019s production assortment shows that a composite profile can have different shapes and thanks to our long-term experience, we are able to manufacture even very shape-complex profiles.<\/p>\n

Our company makes composite profiles using the pultrusion method from resin and reinforcement. The matrix normally used in manufacture is polyester resin, while special applications also involve using epoxide-, vinylester-, phenolic- acrylate or polyurethane resins. The reinforcement mostly used in our applications consists of glass fibre or also carbon fibre. According to required resulting properties of a profile, we can also use direct fibres (so-called roving ones), different types of matting or fabrics, or their combination if necessary.<\/p>\n

Thanks to predominantly their low weight and excellent resistance to corrosion and chemicals, composite profiles are used in various production sectors when a great part of our production capacity involving the making of composite profiles is mainly aimed at manufacturing public transport means, sports accessories, at applications in the electrical engineering, aerospace industry or building engineering.<\/p><\/div>
