I have worked in the trade, import, and supply of GRP fiberglass pipes at various pressures (6 bar, 10 bar, 16 bar) for sizes (160 mm - 3000 mm). I have worked with many well-known Turkish factories, including the Turkish Sopor Factory, Superlite Factory, Essen Factory, Akpor Factory, and others. I have also dealt with high-quality Iranian factories, such as Belva Factory and others.
