WHAT IS FORMWORK ?

- Supports structure and molds to create structures out of concrete- Made by using steel, wood, aluminum and prefabricated forms- Cost of formwork is around 30-40% of the concrete cost

METAL FORMWORKADVANTAG

ESSTEEL ALUMINIUMStronger, durable and longer life than timberformwork

Often used in pre-fabricated formwork

Can be reused many times Strong and light in weight

Can be installed and dismantled with greater easeand speed

The lighter sections will deflect more

Quality of exposed concrete surface is good Can be recycled after smelting

Does not absorb moisture from concrete Highly precise in assembly

Does not shrink or warp Can be reused for more than 300 times

METAL FORMWORKDISADVANTAGESSTEEL ALUMINIUM

Limited size or shape Higher risk of theft

Excessive loss of heat Not field modifiable

Limited fixing Expensive

A very smooth surface will be produced which would give problems for finishing process

Lower transportation cost compared to steel formwork


SUITABILITYSTEEL ALUMINIUM

- Widely used in large projects or in situation where large number reuses of the shuttering is possible

- Suitable for low as well as high rise building

- For heavy concrete work - can be designed for any condition/component of building such as bay windows, stairs

- Suitable for circular or curved shaped structures - such as tanks,

columns, chimneys.

- Bridge construction / Airport construction


COST
