Shuttering can be used to create temporary moulds into which concrete can then be poured to achieve the desired structural shape at a construction site. Shuttering is used in the infrastructure and construction industry to create structures of different sizes using different materials like timber, aluminium, plastic, etc. It must be strong enough to withstand the dead load and the live load during concrete casting. After that, it must hold its form while the concrete hardens. The Shuttering process is time-consuming and can cost 23% to 25% of the total construction costs.
Types of shuttering:
There are six different types of shuttering based on the material used.
- Timber Formwork:
Timber shuttering is one of the most popular forms of formwork in construction. It is vital to inspect the condition of timber before you use it. Timber shuttering has two limitations. It has a limited life span and can be time-consuming for large projects. In timber shuttering, timber should be cut into pieces so that the large pieces can be reused. Shuttering made from timber is best when there are minimal labour costs and when multiple concrete sections need flexible formwork.
- Plywood Shuttering:
Plywood shuttering can be described as an unnaturally manufactured wood sheet that is used to form concrete moulds. It comes in different thicknesses, sizes, and colours. It is lightweight, strong, and durable. Plywood is a popular material for sheathing, lining, and decking in shuttering. Plywood shuttering is similar to timber shuttering in strength, durability and is lightweight. When it comes to cost, it is somewhat similar to timber shuttering except in a few cases.
- Metallic or steel shuttering:
Steel shuttering is a panel made from thin steel plates and joined along their edges by small steel angles. You can attach the panel units using appropriate clamps, bolts, and nuts. This shuttering is used mainly in bridge construction. Because of its durability, more people are going for steel shuttering hire. Although steel shuttering can be expensive, it can be used in a wide range of projects and structures. Steel shuttering provides smooth, levelled concrete surfaces. This is ideal for circular and curved structures.
- Aluminium shuttering:
Aluminium shuttering is very similar to steel shuttering. Aluminium has a lower density than steel which makes it lighter for formwork. Aluminium is lower in strength as compared to steel. These factors must be considered before you use them in a construction project.
- Plastic shuttering:
Plastic shuttering can be achieved using interlocking panels or modular systems made from lightweight and strong plastic. It is best suited for small projects that involve repetitive tasks. It can also be used to build simple concrete structures. Plastic shuttering is lightweight and easy to clean. It is also suitable for multiple uses and large sections.
- Coffer Shuttering:
It consists of two filtering panels that are reinforced with vertical and horizontal stiffeners. They are linked by articulated connectors, which can also be folded for on-site transport. After the concrete has been poured, the coffer shuttering is still in place and acts as reinforcement. These shutters are suitable for all types of structures, including multi-story buildings, houses, and so on.
In case you want to construct some kind of structure, you can contact companies that undertake shuttering plate manufacturing. They will also guide you about the type of shuttering that will suit your purpose.
