Product Description

We specialize in producing large clear pmma tunnel of oceanarium project. Their size could be made fully as customer's requirement. We also undertake the construction of tunnel project. We'd like to supply the installation of entire tunnel project with whom give us an order.

Our product has some advantages, such as sustaining heavy pressure, excellent transparency, free of inclusions, fine mechanical performance.

The tunnel we produced has been exported to many countries, which mainly used in oceanarium and exhibition.
Pmma tunnel material: 100% original lucite material
Pmma tunnel transparency: Above 92%
Process flow of pmma tunnel:
1.100% Original Lucite Material
