Understanding Unistrut Dimensions and Types
Unistrut channels come in various sizes and profiles, making them suitable for a wide range of applications. Understanding these dimensions is crucial for selecting the right channel:
-
Width and Height: Unistrut channels typically come in widths of 1-5/8”, 1-1/4”, and 13/16”. The most popular width is 1-5/8”, which offers greater load-bearing capacity and is widely used in heavy-duty applications.
-
Wall Thickness: Wall thickness varies between 12 gauge, 14 gauge, and 19 gauge, influencing the load capacity and suitability for different applications. Thicker walls generally provide greater strength.
-
Length Options: Common lengths of Unistrut channels are 10’ and 20’. However, custom lengths can be obtained through cutting services, which may reduce shipping costs and material wastage.
-
Height Variations: Channels may also vary in height, allowing for flexibility in mounting configurations. Some channels, like P1000 and P1100, have the same width and height but differ in wall thickness.
