Thickness Types

Corrugated steel sheets come in various thicknesses, commonly ranging from the thinnest 1mm to the relatively thickest 3mm. Depending on the application requirements and load-bearing standards, there are also other specific specifications, such as custom models with thicknesses greater than 3mm. Manufacturers develop even more different thickness specifications based on market supply and demand and the usage environment. The characteristics and applications of corrugated steel sheets of different thicknesses are explained in detail below.

 

Characteristics and Applications of Thinner Steel Sheets

Thinner corrugated steel sheets, such as those with a thickness of 1mm or slightly thicker, are often used in construction for ceilings, wall decorations, or packaging materials due to their light weight, ease of processing, and convenient transportation. These thin sheets are also commonly used to make temporary structures or support plates for light load environments. Furthermore, during the manufacturing process, these thin sheets exhibit excellent corrosion resistance and good durability.

Characteristics and Applications of Thicker Steel Sheets

Corrugated steel sheets with a thickness of 2mm or more possess stronger structural load-bearing capacity. These steel sheets are widely used in building formwork, floor paving, and heavy equipment operating environments due to their excellent compressive strength and stability. In the construction of infrastructure such as bridges and roads, thick corrugated steel plates are also used as important components such as supporting structures and guardrails. These thick plates are manufactured using special processes to ensure their strength and durability.
