It is the oldest formwork system used in the construction industry. This type of formwork is made up of timber. The manufacture process of this type of formwork is simple but it consumes more time for installation and has a low life span. This type is more suitable for small houses of two or three floors, and they are still in use for such constructions.
Steel Formwork is mainly used in major building projects or in cases where the same shuttering can be re-used in large numbers. It is suitable for circular or curved structures such as tanks, columns, chimneys, etc. and is used for structures such as drainage tunnels, bridges and wall retention.
The conventional formwork system usually consists of standard Plywood Panels tied together with timber frame over their backs with horizontal members called walling to resist the weight and horizontal force of wet concrete. In formwork applications, Plywood is mainly used for sheathing, decking and form linings. Plywood formwork has similar properties to Timber formwork including strength, durability and being lightweight. Plywood boards are available in thickness of 6mm, 9mm and 12mm. Basically, the size of Plywood is 8 x 4 (Foot x Foot).
Aluminum Formwork System in India, a comparatively new technology saves time, costs and increases construction efficiency. Aluminum Formwork is widely used for the construction of low and high rises apartments and buildings in Japan, Singapore, Malaysia and the Middle East. Aluminum Formwork is very cost-effective for repeating building layouts and for above-the-plinth work.
Fabric Formwork or Flexible Formwork is the emerging Shuttering Technology which facilitates construction of Complex and Irregular-shaped Structures. Fabric formworks are permeable sheets made of synthetic textiles. The forms take the designed shapes (bags, bolsters, mattresses, or shuttering) under the pressure of pumped concrete mixes or cement mortars.
