Steel Formwork: Why Use It and What Are Its Main Advantages?

Choosing a suitable material for formwork is one of the most vital parts of a concrete construction job, particularly during commercial construction projects. Choosing the wrong kind can be devastating to the entire job. Improperly placed or inferior quality formwork can mean lost time, lost money, and can even cause injuries or death.

For these reasons, it’s imperative to select the right kind of formwork for the job: Steel Formwork, to be exact. In fact, using formwork made from steel is the superior choice for any construction job that requires concrete to be poured, whether it’s for a foundation or something else entirely. It provides many benefits, including:

1. Long-Term, Durable Solution

Steel formwork is the perfect long-term solution for a concrete construction job. Did you know that when it’s properly maintained, it can last up to 2,000 work cycles? Steel is one of the strongest and most durable metals, which is why it’s such an excellent choice for concrete jobs. It has a much longer lifespan, particularly compared to other types of formwork like wood.

2. Save Money

Though steel is more expensive right out the gate, it’s actually the more economical choice in the long run. Its superior durability and the fact that it can be reused so many times is what makes it so cost-effective. Also, the old saying is very true: you get what you pay for. Purchasing inferior-quality formworks ultimately cost more money when they don’t last as long or break. Steel is the longest-lasting option and, therefore, the most affordable overall.

3. Extremely Strong

Steel is an extremely strong metal, and when it’s used for formwork, it can be made to withstand very heavy loads. This makes it ideal for large-scale concrete projects as well as small ones, and this inherent versatility is another excellent advantage.

4. Great Versatility

Steel formwork also has excellent versatility, which is why it’s so commonly used for concrete projects. Some typical applications for this type of formwork include foundations, tieless column solutions, cap formwork, and bridge columns. However, it can also be customized to virtually any project, which is why it can also be used for high-rise buildings, general structures, non-residential projects, power plants, tunnels, and, of course, it’s extremely well-suited for industrial projects.

5. Clean Concrete Finish

Using wooden or other materials for concrete formwork can sometimes leave texture onto the concrete finish itself once it’s completely cured (which is different from conventional drying). However, using steel leaves a flawless and clean concrete finish. Using tieless formwork improves the finish even more, and they also lower overall labor costs from patching or grouting tie holes.

6. Non-Porous and Non-Absorbent

Formwork made from timber is essentially porous and absorbent. Steel doesn’t present this unique issue. If the wood is completely dry, it will act like a sponge, soaking up the water from the concrete throughout the curing process. This weakens the integrity and stability of the entire concrete structure. Timber also can’t be recycled because it simply can’t be used more than two or three times. Retaining a very high level of moisture (over 20%) can lead to joints opening or even breakage. With steel, excess moisture retainment isn’t even an issue, making it the superior choice.

Choose Steel for Concrete Formworks

It’s easy to see why steel is the better and more cost-effective choice for concrete formworks. Steel is incredibly strong and durable, it doesn’t absorb moisture, it allows for a clean concrete finish, and it’s the perfect long-term solution. After all, it can be used up to about 2,000 different times as long as it’s been appropriately maintained. For those reasons and more, consider switching to steel for concrete formwork, which is incredibly versatile and can be used for virtually any structural application that involves concrete.
