# Weldplast Technology

> Romanian manufacturer and distributor of industrial plastic equipment, including chemical-resistant tanks, hydrocarbon and grease separators, floating fish cages, and floating HDPE pontoons.

Weldplast Technology SRL designs and fabricates custom plastic equipment in PE, PP, PVC-U, PVC-C, PVDF, PP-H, and HDPE for industrial, environmental, food, aquaculture, and offshore applications. The company is based in Carcea (Dolj, Romania), serves Romania, and lists export projects or markets in Greece, Serbia, Bulgaria, Hungary, Moldova, Germany, Denmark, Austria, and the wider region. Weldplast also provides technical catalogs for industrial fittings, valves, piping systems, and ventilation components available by quote request.

The site is published in Romanian (default), English (`/en/...`), and Spanish (`/es/...`). Main pages and project case studies have Romanian, English, and Spanish equivalents. The industrial catalog has localized entry points and quote flows; product names and technical specifications are kept precise for identification. The ventilation catalog is Romanian-only for now and uses Romanian fallback URLs.
