Various Types of Shuttering

Generally there are three types of shuttering.

1. Steel Shuttering
2. Wooden Planks Shuttering
3. Temporary Brick Masonry Shuttering

Steel Shuttering:
Steel Shuttering Plate is the best type of shuttering because this is water tight shuttering which can bear the load of cement concrete placed on it. This shuttering gives leveled surface which has good appearance. If the plaster is required, the thickness of plaster will be less.   

Note: As this is water tight shuttering, it is considered the best shuttering.

Wooden Plank Shuttering:
Wooden planks shuttering is used by contractors because this shuttering is cheap and available easily. But this type of shuttering affects on the strength of concrete and has some disadvantages which are given below.

Disadvantages:

• This is not water tight shuttering as the size and thickness of planks differ and are not of the same size. Due to this difference the water and cement flow to the ground from the joints.
• Bottom level of the RCC slab is not in straight line, due to this the thickness of plates mose which remains week.
• Due to leakage of the cement slurry through the joint, earth work below ''Ballies'' may settle and create problems.
• In some cases wooden planks can not bear the weight of the concrete. Due to low capacity there is bending or deflection in wooden planks or the planks may be broken.

Temporary Brick Masonry Shuttering:
In some cases labor contractor uses Temporary Brick Masonry in mud for vertical shuttering of the sides of beams, to fascia etc. This shuttering should be avoided as this process of shuttering reduces the strength of concrete by soaking cement slurry and no proper compaction is made as this will not bear the pressure of vibrator.
