FRP Duct Systems & Industrial Chemical Ventilation

Nantong Endura Composites Co., Ltd. supplies molded fiberglass FRP grating, grating cover panels, pultruded grating and pultruded structural profiles under the Endura identity, together with pipe, tank and rotational structures made through an integrated pultrusion-and-winding route. The current official site describes glass reinforcement with unsaturated resin and places these families in chemical platforms, municipal walkways, wastewater treatment, photovoltaic maintenance, building and power applications. The China Composites Expo directory independently supports the exhibitor identity and its grating, cover, profile and engineering-service scope. GetFRP assigns only product-demand phrases that the official catalog actually supports: fiberglass and FRP grating, pultruded fiberglass profiles and fiberglass-reinforced pipe. Corrosion, load, fire, electrical or service-life performance must be checked against the selected resin, reinforcement architecture, section, thickness, span and current product-specific evidence. No establishment year, certification or approval is inferred from a website copyright line.

Lianyungang Weide Composite Materials Facilities Co., Ltd. says on its current official website that it was established in 2001 and develops and manufactures composite-production equipment. The published range covers continuous-filament-winding FRP pipe lines, high-pressure hydrogen-cylinder winding lines, four-axis and horizontal winding machines, high-pressure epoxy-pipe lines, centrifugal-casting GRP pipe lines, lighting-pole lines and supporting manipulators, curing ovens, resin-supply, intelligent feeding, conveying, joint-making and quality-assurance systems. China Composites Expo's L directory lists the matching exhibitor. Weide sells the machinery used to make pipes, cylinders and poles; those outputs are not presented as Weide-manufactured FRP or carbon-fiber products. GetFRP therefore excludes reinforcement, FRP-pipe and finished-cylinder supplier keywords. Capacity, performance, import-substitution, service-life and mechanical-property statements are supplier claims that must be validated against the quoted configuration, representative trials, FAT, SAT and contractual acceptance records.
