At present, the formworks with different raw materials are mainly as follows.
1. Wood formwork, which is light and low in cost, but the durability is not good, and the recycle rate is low.
2. Steel formwork, which is strong, good recycling,but very heavy and high cost .
3. Plastic formwork, which is not afraid of water, relatively low cost, durable, but not strong enough.
4. Aluminum formwork, which has inherent advantages in stability and bearing capacity, short construction period, wide application, few joints(seams), high precision, low time cost, and can help construction enterprises and workers to reduce work intensity and technical risks.

Analysis of different formwork raw materials and advantages
1. Wood formwork: relatively light, easy for construction, low management cost, but poor durability, and very low recycling rate.
2. Steel formwork: high strength, high recycling rate, but it is heavy, inconvenient for construction and high cost.
3. Aluminum formwork: high strength of aluminum alloy, not easy to rust, can be recycled with large quantity, long life time, high recycling rate, slightly heavier than wood formwork, but much lighter than steel formwork. Convenient for construction, but much more expensive than wood formwork, slightly more expensive than steel formwork.
