Types And Applications Of Steel Formwork In Construction

 

Construction steel formwork is a high-strength, reusable steel formwork system used for concrete casting and shaping.

Through precise modular design, it provides reliable concrete forming solutions for various construction projects, ensuring that the cast concrete components have accurate dimensions, fixed structural contours, and a smooth and aesthetically pleasing surface.

 

Main Types and Uses:

Classified by project type: Primarily divided into building (housing construction) steel formwork and bridge steel formwork.

 

Classified by structural shape: Includes box girder formwork, T-beam formwork, cap beam formwork, pier and column formwork, circular formwork, and various protective beam formwork, to meet the casting needs of concrete components of different shapes.

 

Modular steel formwork: Composed of standardized flat formwork, inner corner molds, outer corner molds, and other components, flexibly assembled using U-shaped clips, L-shaped pins, and other connectors.

 

It is suitable for various cast-in-place reinforced concrete structures such as beams, columns, slabs, and walls.

 

 

Steel Formwork Specification

Steel formwork is usually designed using a modular system. The width module increases in increments of 50mm, and the length increases in increments of 150mm, allowing for the assembly of formwork of any size that is a multiple of 50mm in both horizontal and vertical directions. In the design of combined steel formwork, if the modular dimensions do not match the 50mm increment, the gaps can be filled with wooden formwork.

1.1 Length: Available in seven specifications: 450mm, 600mm, 750mm, 900mm, 1200mm, 1500mm, and 1800mm. Width: Available in eleven specifications: 100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, and 600mm.

 

Steel Formwork Accessories

An efficient and safe steel formwork system depends not only on the quality of the formwork itself, but also on the correct selection and use of its specialized accessories. Our accessories are designed to facilitate rapid assembly, precise alignment, and stable support of the formwork, thereby improving overall construction efficiency and safety.

 

1. U-clip The main connecting component of the formwork, used for assembling adjacent formwork panels.

2. Screw Thread Tie Rod Used to connect formwork panels on both sides of the wall, maintaining the wall thickness, bearing the lateral pressure and horizontal load of the concrete, and preventing the formwork from deforming.

3. Two-wing Nut, together with the screw thread tie rods, form the wall tie rod system, securing the formwork panels during concrete pouring.

 

 

Steel Formwork Assembly

Fast Connection, Robust and Stable: Unveiling the Efficient Assembly of Steel Formwork with U-Shaped Clips Want to make the complex assembly of steel formwork as simple and efficient as building with LEGOs?

This video will visually demonstrate the standard operating procedure of the U-shaped clip (U Clip), the core connecting component of the steel formwork system.

You will see firsthand how it enables quick and precise joining of the formwork, ensuring tight and reliable connections every time, resulting in a smooth and even concrete surface.

 

We strictly adhere to standardized production processes and quality control systems to ensure that every steel formwork panel achieves optimal performance.

Our core processes follow specifications such as the “Technical Regulations for the Processing of Standardized All-Steel Large Formwork.”

 

Key Production Steps:

1. Design and Cutting
Detailed panel design is based on engineering drawings. High-precision equipment is used to cut and process raw materials such as Q235 steel plates.

2. Assembly and Welding
Panels, edge ribs, and longitudinal and transverse ribs are precisely positioned and assembled on dedicated fixtures. Certified welders use compliant processes to ensure structural strength, with particular attention paid to critical areas such as corners.

3. Correction and Grinding
The welded formwork is inspected and straightened to ensure panel flatness. All welds and burrs are finely ground to ensure a smooth surface.

4. Drilling and Anti-corrosion Treatment
Connection holes are precisely drilled in the panels according to the design. Thorough rust removal is performed, and high-quality anti-rust paint is applied to extend the service life of the formwork in outdoor environments.

5. Final Inspection and Warehousing
A final dimensional check and quality acceptance are performed. Qualified products are marked with specifications and models before being stored in the warehouse for shipment.

 

 

 

Steel Formwork Advantage

Steel Formwork FAQ

 

Q1:What are the main advantages of steel formwork compared to traditional wooden formwork?

A1:The core advantages of steel formwork lie in its exceptionally long service life (up to 200 cycles or more), superior concrete forming quality (smooth surface, precise dimensions), and higher construction efficiency. Although the initial investment is higher, the long-term overall cost is lower, and it is more environmentally friendly.

 

Q2:What is the typical service life of steel formwork? How should it be maintained?

A2:Under proper use and maintenance, steel formwork can be reused more than 200 times. Key maintenance points include: thoroughly cleaning the surface of cement slurry after each use, inspecting and repairing minor deformations, applying release agent and anti-rust paint before and after storage, and avoiding prolonged exposure to sunlight and rain.

 

Q3:Can you provide custom-sized or specially shaped formwork?

A3:Yes. Customization is one of our core strengths. We have a professional design team that can produce various irregular formwork, such as curved wall formwork and special node formwork, based on your engineering drawings or specific requirements.

 

Q4: What precautions should be taken during the transportation and on-site storage of formwork?
