Metal sub-girts are continuous framing structures typically made with 16- to 22-gauge galvanized steel, extensively used for mounting systems in roofing and cladding projects.

These components are used to attach sidings to exterior wooden, brick, or dense (e.g., concrete) walls. Although not visible after the siding project is completed, they are fundamental to the stability and durability of the siding.

Metal sub-girts come in different shapes, lengths, and thicknesses depending on their applications, the substrates they are installed on, and the construction design. Sub-girts can be installed horizontally or vertically. To reduce installation time, they can be pre-punched based on the ease of installation required.

Profelez can produce any type of sub-girt based on construction requirements. We can also provide recommendations based on our extensive experience installing almost all types of sidings and working with various building materials.

The most popular types of metal sub-girts are Z-bars, L-bars, hat channels, C-channels, and angles.
