Ceiling Cross Tee Grid Roll Forming Machine

The ceiling T grid hanging system is crucial in modern building interiors, providing structural support and an aesthetic finish for ceilings. This system consists of three specialized cold roll forming machines, each designed to produce specific elements essential for a complete ceiling installation: the Main Tee Grid, Cross Tee Grid, and Wall Angle Profile.

1. Main Tee Grid Making Machine

The Main Tee Grid is the backbone of the ceiling grid structure, dictating the overall layout and load-bearing capacity.

The production line for the Main Tee Grid incorporates several key components:

Decoilers: These units are responsible for unwinding the metal coils, ensuring a smooth and continuous feed of raw material into the production process.
Main roll forming machine: As the core of the line, it transforms the flat metal strip into the distinct T-shaped profile of the Main Tee Grid through precise roll forming operations.
Automatic hydraulic cutting off station: This device cuts the formed T bars to the required length with high precision, streamlining the production process.
Hydraulic cooling station and electric control system: The cooling station helps maintain the optimal temperature of the machinery during operation, while the electric control system oversees and regulates all aspects of the production process.

The Main Tee bar specifications are as follows:

Sizes: H38*24mm and H32*24mm
Length: 3600mm
Thickness: 0.20 – 0.40mm

2. Cross Tee Grid Making Machine

The cross-tee grid plays a vital role in providing additional support and stability to the ceiling grid, allowing for a more even distribution of weight. The production line for the Cross Tee Grid comprises:

Decoilers: Similar to the Main Tee Grid line, these supply the necessary metal strip.
Main roll forming machine: It shapes the metal into the specific Cross Tee Grid profile.
Automatic hydraulic cutting off station: Ensures accurate length cutting of the Cross T bars.
Hydraulic cooling station and electric control system: Maintains machine performance and controls production parameters.

The Cross Tee Grid dimensions are:

Sizes: H26*24mm and H24*23mm
Lengths: 1200mm and 600mm
Thickness: 0.20 – 0.40mm

3. Wall Angle Profile Making Machine

The Wall Angle Profile is used to finish the edges and corners of the ceiling installation, providing a clean and professional look. The Wall Angle Profile making machine is composed of:

Decoiler: Unwinds the metal coil for production initiation.
Main roll forming machine: Forms the metal into the desired angle profile.
Automatic hydraulic cutting off station: Cuts the profiles to the appropriate lengths.
Hydraulic cooling station and electric control system: Keeps the machine running smoothly and under control.

The Wall Angle Profile specifications are:

Angles: 22x22mm & 22x20mm
Produced according to customer’s request
Thickness: 0.3 – 0.50mm

In addition to the T grid production machines, MASSCA offers a diverse range of completely automatic metal drop ceiling tile production lines. These lines are capable of manufacturing ceiling boards in various sizes, including 600*600mm, 300*300mm, and 600*1200mm. The metal ceiling tiles produced by these machines can be integrated into an entire exposed metal ceiling suspending system, providing a seamless and stylish solution for modern building interiors.
