Circular Column Formwork
1. Made of plywood, lightweight and easy to handle.
2. Grooves to prevent concrete leakage
3. Easy to cut
4. Efficient installation and disassembly
5. The concrete surface is smooth and does not require rework
Application
For concrete forming of circular columns
Installation
Treat inner ply film with concrete release agent firstly.
Fix the steel belts horizontally according to the lines.
If the height is more than 3000mm , please install it as the indication below.
From feedback on site, only 2 skilled workers can install 15 circular columns in 8 hours.
Dismantling
Simply untie the steel belts and the ply will separate easily.
Maintenance & Storage
Lightly treat the ply film with oil before next usage.
place the formwork vertical, away from direct sunlight and water.
