What Are The Differences between Aluminum - Framed Formwork And Steel - Framed Formwork?

I. Material Features: What They're Made of Matters

(A) Aluminum - framed Formwork: Light and Strong, Like a Trusty Tool

• The frame of aluminum - framed formwork is made from 6061 - T6 aluminum alloy. This stuff is amazing! It's light, but it's also tough. Think about a big aluminum alloy panel, say, 300cm by 100cm. It only weighs 70.9kg. Two workers can easily carry it around. This is a huge help at construction sites. In places where cranes can't reach, like small spaces inside a building or when a project just starts and there aren't any cranes yet, moving and setting up aluminum - framed formwork is a piece of cake. You don't need those big, heavy lifting machines. This saves money on renting equipment and makes the work go smoother. So, the construction can be finished much quicker.

(B) Steel - framed Formwork: Solid and Long - lasting, Like a Reliable Workhorse

• Steel - framed formwork uses Q355B material for its frame. It's really strong and steady. It can handle the pressure when you're pouring concrete without breaking a sweat. Inside, there's a 12 - mm - thick piece of good - quality hardwood plywood with a PP plastic film on it. This makes the formwork light enough to work with, but it's also tough and can keep out water. The plywood can be used over and over again, around 30 times. So, over time, it can save you a lot of money. Even though steel - framed formwork is heavier than the aluminum kind, its strong structure makes it a great choice for big construction projects and places where the building work is a bit more challenging.

II. Structural Design: Built to Fit Different Jobs

(A) Aluminum - framed Formwork: Many Sizes and Handy Parts for Easy Work

• Aluminum - framed formwork comes in all sorts of panel sizes. The widths can be 75 cm, 125 cm, 150 cm, 250 cm, or 300 cm. And the height can be changed using four different - width (25 cm, 50 cm, 75 cm, 100 cm) standard parts. This means it can fit all kinds of building shapes and sizes. The parts that connect the panels are really well - thought - out. The strong clamps hold the panels together tightly so they fit just right. The tie - rod system makes the whole formwork stronger and more stable, like a well - built fence. The articulated corners are super flexible and can bend to angles of 75° or more. They're perfect for joining panels at the corners of walls, making sure the concrete in the corners turns out just right. The diagonal braces help line up the formwork and place precast concrete parts in the right spot. The platform frame is like a little work platform in the air for the workers. It gives them a safe and easy place to work. Accessories like large washer nuts work together to make putting the formwork together and taking it apart really simple.

(B) Steel - framed Formwork: Modular and Adjustable for Any Job

• Steel - framed formwork panels are sized from 600 mm to 3000 mm in height and 500 mm to 1200 mm in width. You can even change the working width of a single panel right at the construction site if you need to. It has a ton of useful accessories. The strong clamps not only connect the panels but can also move the panels closer or farther apart, up to 150 mm. This makes sure the formwork is flat and there are no gaps for the concrete to leak through. The column clamps are used when building columns. By putting them in different holes on the panels, you can change the size of the column you're building. You can make columns anywhere from 150×150 mm to 1050×1050 mm, and you can be really precise, with an error of only 50 mm. There are also special parts for different building jobs. For example, there are parts for building small - section shafts, inner - angle formwork for corners, and articulated - angle formwork for odd - shaped connections. These parts make it possible to build even the most complicated buildings.

III. Application Scenarios: Where They Work Best

(A) Aluminum - framed Formwork: Ideal for Special Situations

• When building shear - walls, the LG - AF panel of aluminum - framed formwork is a dream to use. It's easy to hold and move around. You can pour concrete up to 3 meters high in one go. Workers can put the panels together to fit the size of the shear - wall without any trouble, and they don't need those big, complicated lifting machines. This makes the work go much faster. And no matter what the building looks like or how the walls are designed, it can still do a great job, making sure the wall is built just right. In small spaces like elevator shafts and stairwells, the fact that aluminum - framed formwork is light is a huge plus. Workers don't have to worry about the danger of using cranes in tight spots. They can easily move and set up the formwork. The different panels and parts can fit into all the tricky corners and joints in these areas, making the structure more stable and reducing any gaps or mistakes. At the start of building a foundation, when there might not be enough cranes, aluminum - framed formwork can still be used quickly and safely. The accessories give different ways to hold up the formwork, and it works well with wood. You can change how the formwork is supported based on the shape of the foundation. When building rectangular piers, the extra scaffolding brackets are like a safe little platform for the workers. The parts of the formwork can be put in place easily, without a crane. It's light but strong, and you can adjust the size of the column. With different ways to combine the panels, it can handle piers of all sizes, making the piers look great and the building process faster.

(B) Steel - framed Formwork: A Jack - of - all - Trades

• Steel - framed formwork is really flexible and can be used in all kinds of building projects. When working on a foundation, it can be set up and taken down quickly to fit the shape and size of the foundation. For basements, you can use its adjustability to build all sorts of complex underground structures. When building a retaining wall, it can meet the needs of different wall heights and shapes, making the wall strong and looking good. For swimming pools, it can be adjusted to the exact shape needed. In shaft and tunnel construction, especially when building the inner part of small - section shafts, the special inner - shaft formwork parts make it easy to put the formwork up and take it down, which speeds up the work. When building columns, the column clamps can be adjusted to pour columns of any size, making sure they're straight and the right size. It can also be used at the corners and T - shaped joints of buildings, and for single - sided formwork construction, like when you're pouring a wall up to 6 meters high all at once.

Ⅳ. In conclusion

• Both aluminum - framed and steel - framed formwork have their own advantages. Aluminum - framed formwork is great when you need something light and easy to move, especially in small spaces or for certain types of structures. Steel - framed formwork is really good because it's flexible, has lots of useful parts, and can be used over and over again. People in the construction business should think about things like what the construction site is like, what kind of building they're making, how fast they need to finish, and how much money they have to spend when they're choosing formwork. That way, they can pick the best one for their project and build something great.
