Why Steel Formwork Is the Most Suitable for Large Construction Projects
Tuesday, April 28, 2020 7:21:01 AM Australia/Melbourne
Timber or steel – contractors often debate about which of the two to use for formwork.
Timber is lightweight, making it easy to handle and disassemble. It is also flexible and damaged parts are easily replaceable. On the other hand, timber framework has limited re-use because the material can shrink or expand when exposed to moisture. For this reason, many contractors opt for steel formwork that is durable and can be used for a long time. Both types of formwork are for sale but which is best for your project?
Steel Formwork Is Ideal for Heavy Loads and Heavy Duty
Timber is one of the most commonly used materials for formwork. The formwork is lightweight and easily workable. But it is fabricated on site, making it a time-consuming effort for large structures. This is where the popularity of steel formwork in large construction sites comes in.
Steel formwork is increasingly popular because of its uniform size and surface, extended life span and reusability. The material might cost more than timber but its long-term benefits for contractors are worth the price. It is ideal for contractors with a large number of projects lined up.
Moreover, steel has an edge on timber due to various factors:
- Durability: The strength of steel formwork makes them ideal for many large projects.
- Smooth Finish: The material makes way for a smooth concrete surface afterwards.
- Waterproof: Steel isn’t easily affected by water and can minimise the honeycombing effect.
- Easy Installation: Save time with how easy it is to install and dismantle steel formwork.
These aren’t the only features of steel formwork. Steel shuttering is actually ideal for contractors who are building curved or circular structures. As such, it is suitable for structures like chimneys, columns, sewers, tanks and tunnels.
Delve Deeper into the Technicalities of Steel Formwork
The panels used for steel formwork feature thin plates stiffened along the edges based on the formwork design or strength requirement. These panels come in various shapes and sizes based on which ones are most often used by the contractor. They are held together by clamps and bolts that are equally durable. Contractors can also invest in diagonal flat bars to enhance the strength and stiffness of the steel plates.
Steel is a suitable option for contractors who are looking for formwork material that can accommodate several sessions of laying concrete — especially in the repetitive casting operation during precast concreting. Steel may have a higher initial cost than timber but it can be used many more times than the latter. As such, contractors can save on the cost of formwork in the long run.
So from slabs and panels to clamps and bolts to other components of formwork, consider our steel as the most cost-effective choice for large projects. We provide innovative formwork systems like a sustainable dome form that eliminates hard filling and speeds up the process of creating concrete slabs.
