How do you install Z purlins?

When placing Cee purlins into a roof the purlin should be bolted to the top side face of the cleat with the open C facing up the hill. With Zeds or Z section the purlin should be bolted to the lower side of the cleat with the upper flange facing up the hill.

What is a purlin and girt?

Purlins are specific to the roof. In the shape of a “Z”, a purlin is a horizontal structural member that supports roof covering and carries loads to the primary frame. Also, in the shape of a “Z”, a girt is a horizontal structural member that is attached to sidewall or end wall columns and supports paneling.

How far can you span Z purlins?

A four-inch purlin can span 12 feet. A six-inch purlin can span 18 feet. An eight-inch purlin can span 25 feet. A ten-inch purlin can span 30 feet.

What is the purpose of a Girt?

In architecture or structural engineering, a girt, also known as a sheeting rail, is a horizontal structural member in a framed wall. Girts provide lateral support to the wall panel, primarily, to resist wind loads.

How far will 10 Z purlin span?

30 feet
A ten-inch purlin can span 30 feet.

Why are purlins used?

Purlins provide additional support for the roof: They create a horizontal “diaphragm” that supports the weight of your building’s roof deck – whatever material you use for the roof itself. They also help make your entire roof structure more rigid.

What is the difference between girder and girt?

is that girder is a beam of steel, wood, or reinforced concrete, used as a main horizontal support in a building or structure while girt is a horizontal structural member of post and beam architecture, typically attached to bridge two or more vertical members such as corner posts.

What are the purpose of Z girts in insulation?

Z Girts are typically produced to hold in place different thicknesses of rigid or semi- rigid insulation. Varying the length of the Z flange can allow for insulation that can enhance the R-value of a building.

What are the different types of Z girts?

Z Girts, also known as “Z-Bar, Z-Channel, and Zee” are all terms that describe the same type of profile. This cladding attachment system consists of continuous galvanized steel framing members which can be applied vertically, horizontally or crossed.

How big can a notched Z Girt be?

Notched Z girts are similar to standard Z girts with the exception of notching which facilitates application of the Z girt over a profiled metal liner acting as a vapour barrier. Available in 10 to 26 gauge. Length up to 12’ long (10’ standard) Standard as Galvanized G90 material *other materials are also available.

What is the function of the Z Girt profile?

Varying the length of the Z flange can allow for insulation that can enhance the R-value of a building. The Z girt profile functions as structural supported fastening point, a wall cavity for insulation and an exterior fixing point for cladding within one assembly.
