  • The manufacturing process of GRP chemical tanks involves a technique called 'wet lay-up' or ' filament winding.' In wet lay-up, layers of glass fiber mats soaked in resin are laid over a mold, while in filament winding, continuous glass fibers are wound around a rotating mandrel in a predetermined pattern. Both methods ensure a uniform distribution of fibers and resin, resulting in a tank with consistent strength and thickness.
  • Threaded rods are long, cylindrical rods with threads on both ends. They are often used to secure objects together or to anchor structures in place. In order to secure objects to a threaded rod, holes must be drilled through the rod itself. This is where threaded rod drill bits come in handy.
