The building materials for bridges are stones, timber and steel, and more recently reinforced and pre-stressed concrete. For special elements aluminum and its alloys and some types of plastics are used. These materials have different qualities of strength, workability, durability and resistance against corrosion. They differ also in their structure, texture and color or in the possibilities of surface treatment with differing texture and color. For bridges one should use that material which results in the best bridge regarding shape, technical quality, economics and compatibility with the environment.
PP Plastic Plywood used to Bridges Construction.
major advantages of plastic templates:
1. Easy to dismount,release agent free,nonstick cement,smooth finishing.
2. Light in weight,easy to use,can be cut to various size.
3. More reuse times than normal film faced plywood.
4. Waterproof performance and wear & tear resistant.
