Fully Automatic Grout Keel Production Line for Light Steel Integrated Houses, Concrete Grouting Walls and Steel Structure Construction
The Grout Keel Production Line is an automatic roll forming solution designed for producing grout keels used in light steel integrated houses and modern steel structure construction.
Grout keel is mainly used together with grout mesh molds. The grout mesh mold is attached to the grout keel frame, and the internal cavity is then filled with concrete to form fire-insulating, sound-insulating and load-bearing walls.
The production line integrates uncoiling, forming, cutting, conveying, manipulator feeding, punching and final discharge into one continuous automatic production process, reducing manual operation and improving production efficiency.

The complete production process is automatically connected from uncoiling to forming, cutting, conveying, manipulator feeding, punching and final discharge.
The machine is equipped with 9 sets of molds and can produce various types of grout keel profiles for different construction requirements.
Multiple production procedures are integrated into one line, helping reduce manual handling and simplify the manufacturing process.
Grout keels synthesized through hot-dip galvanizing technology provide corrosion resistance and are designed for long-term construction use.
The large kidney-hole design facilitates double pouring and improves concrete flow during the wall construction process.
The closed cavity structure helps improve water resistance and reduce noise transmission within the wall system.
Raw material is automatically fed into the production line.
The steel strip is continuously formed into the required grout keel profile.
The formed profile is cut according to the required production length.
The finished profile is automatically transferred to the next station.
The manipulator automatically transfers the workpiece for further processing.
Required holes are automatically processed on the grout keel profile.
Finished grout keels are automatically discharged for collection.




The production line combines multiple processing stages into an automatic workflow, reducing dependence on manual operation.
With 9 sets of molds, the machine can manufacture different grout keel profiles to meet diverse project requirements.
Grout keel construction features fast installation, convenient material handling and a simplified construction process.
Hot-dip galvanized grout keel provides improved resistance to corrosion and is suitable for construction applications.
The grout keel wall system can provide fire insulation, sound insulation, water resistance and load-bearing functions when combined with the corresponding construction process.
The simple construction process can help shorten the overall construction period and improve material handling efficiency.
Grout keels have applications in a range of steel construction and wall-building projects, particularly in light steel integrated construction.

Used as part of wall construction systems for light steel residential buildings.
Suitable for integrated light steel housing construction and concrete grouting walls.
Applicable to secondary structures of steel structure buildings.
Used for secondary structures and wall construction in high-rise residential projects.
Suitable for secondary partition walls in frame-store construction.
Designed for wall systems where grout mesh molds and concrete are combined with the grout keel frame.
* Machine configuration, profile design, production specifications and auxiliary equipment can be discussed according to the customer's project requirements.
The production line forms steel coil into the required grout keel profile.
The grout mesh mold is attached to the grout keel frame to create the required wall cavity structure.
Concrete is filled into the internal cavity to form the wall structure.
The resulting wall system can provide load-bearing, fire-insulating and sound-insulating functions according to the construction design.
Our engineering team provides technical support during machine installation, commissioning and production.
We assist customers in getting the production line installed and running according to the agreed project requirements.
Zhongtuo focuses on long-term cooperation and practical solutions throughout the machine operation process.
