Manufacturing Processes

Roll Forming

Roll forming is a process used to create long and continuous aluminum panel sheets. In this process, a flat metal strip is fed through a series of rollers that gradually shape it into the desired profile. The rollers are arranged in pairs, with each pair bending the metal strip a little more than the previous one. The final shape of the profile is determined by the shape of the rollers.

Roll forming is a highly efficient process that allows for the production of large quantities of aluminum panel sheets with consistent quality and accuracy. It is commonly used in the construction industry for applications such as roofing, cladding, and facades.


Extrusion is another process used to manufacture aluminum panel sheets. In this process, a heated aluminum billet is forced through a die to create a specific shape. The resulting profile is then cooled and cut to the desired length.

Extrusion allows for the creation of complex shapes and profiles that cannot be achieved through roll forming. It is commonly used in the manufacturing of products such as window frames, door frames, and curtain walls.


Anodizing is a process used to enhance the corrosion resistance and durability of aluminum panel sheets. In this process, the aluminum surface is treated with an electrolytic solution and an electric current is applied to create a layer of oxide on the surface.

The resulting oxide layer is hard, durable, and resistant to corrosion. It also provides a surface that can be colored or dyed to create a range of finishes and textures.

Overall, the manufacturing processes used to create aluminum panel sheets are highly efficient and effective. Each process has its own advantages and is used in different applications depending on the desired outcome.
