5. Stress analysis of GRP Panel
- GRP Water tank panel is designed with special shape for maximizing safety against stress and deformation, so it has better structural strength than normal circle designed panel.
- As GRP Water panel is manufactured by oil-hydraulic press under high temperature and high pressure, it maintain stop water pressure strength and there is nodimensional deviation by temperature change.
