What Is Girt (Sheeting Rail) In Construction?
Girt, also known as sheeting rail, is a horizontal structural member in a framed wall used in architecture or structural engineering. It provides lateral support to the wall panel and predominantly serves to resist wind loads.
Girts usually consist of either steel or timber and are connected to studs that form the frame of the wall, giving it more strength and stability.
Additionally, they can be used as a base for mounting other construction elements, such as external cladding and insulation. Girts are an essential component of any well-structured framed wall system, providing stability and durability throughout its lifetime.
What Is The Difference Between A Girt And A Purlin?
Girts and purlins are horizontal structural elements used in building construction to provide fastening points for roof sheets and cladding.
While they are essentially the same product, they are referred to differently depending on their location – as girts in the walls of a structure and as purlins when part of the roof.
Girts run lengthways along the frame of a structure, providing support while also enabling an attachment point for roof sheets and cladding.
Purlins serve a similar purpose but often form part of a larger truss system due to their role in the roof section.
What Is The Difference Between Girt And Girder?
Girts and girders are both structural elements used to support weight and provide stability. While there are some similarities between the two, there are also differences that can affect how they are used. Girts are composed of smaller steel girders rolled into shape.
They usually measure 1 meter or 3 feet deep or less in size and help resist shear loads. On the other hand, larger girders measuring at least 1 m/3 feet deep must be constructed from several pieces of steel plate welded or bolted together which helps increase stability when carrying heavier loads.
What Is The Purpose Of A Girt?
The purpose of a girt is to provide lateral support to the wall panel in framed walls and to resist wind loads. Girts are typically constructed using either steel or wood, depending upon the application, and are connected between two vertical members such as columns or posts.
Girts provide strength so that the wall can support heavier loads while still providing effective structural integrity. They also help prevent warping or sagging of the wall panel over time, ensuring it remains firmly in place for many years.
Where Are Girts Used?
Girts are a type of structural steel that is used for supporting roofing and wall sheeting in various types of buildings, including industrial, rural, and commercial buildings.
They are typically attached to a fabricated steel frame, however, they can also be used in small to medium-sized buildings as part of the structural framework itself.
Stramit® Purlins and Girts are highly versatile due to their range of sizes, shapes, and finishes which makes them a popular choice amongst many construction professionals.
What Is Girt Spacing?
Girt spacing is a measurement that is used in post-frame construction, which typically involves 2×6 girts nailed to the outside of the post, spaced 24” in the center.
This type of spacing provides enough support for the structure and ensures it remains rigid and secure. It is a common practice used in post-frame construction for buildings like barns, warehouses, and shops due to its cost-effectiveness and quick installation time.
