Z Purlins Load Span Tables

June 10, 2018

Steel structures are becoming increasingly popular in the construction industry for a variety of reasons. One of the key components of a steel structure is the Z purlin, which provides support and stability to the building. But in order to build a safe and secure structure, it’s important to know the load span tables for Z purlins. In this article, we will explore what Z purlins are, how they are used in construction, and the different load spanning tables that apply to them.

What are Z Purlins? Z purlins are C-shaped steel channels that are used to provide support and stability to the frame of a building. They are typically used in roof and wall constructions, as well as in mezzanine floors and other structural applications. Z purlins have been used for decades in the construction industry due to their strength and ease of installation. They are available in a variety of sizes, thicknesses, and lengths, and are usually made from galvanized steel or aluminum.

Z purlins are used for a variety of reasons, including providing support and strength to the frame of a building, as well as providing a neat and uniform appearance to the structure. However, when using Z purlins, it’s important to ensure that the correct load span tables are adhered to. This ensures that the purlins can adequately support the weight of the building and the materials used in its construction.

Load Span Tables for Z Purlins are determined by the material used in the purlin's construction. Different materials have different load capacities, so it’s important to select the correct material for the job. Generally, the load span tables for Z purlins are divided into three categories: lightweight, medium-weight, and heavy-weight. Within each category, there are different sizes and thicknesses available, and the load span tables vary depending on the size and thickness of the purlin.

Lightweight Z purlins are usually made from aluminum and have a lower load capacity than their heavier counterparts. The load span tables for lightweight Z purlins are typically lower than for heavier Z purlins, but they also offer a cost-effective solution for lighter-duty applications. Medium-weight Z purlins are usually made from galvanized steel and have a higher load capacity than lightweight Z purlins. The load span tables for medium-weight Z purlins typically fall between those of lightweight and heavy-weight Z purlins, offering a good balance between cost and strength.

Finally, heavy-weight Z purlins are usually made from stainless steel and offer the highest load capacity of all Z purlins. The load span tables for heavy-weight Z purlins are the highest of all Z purlin types, making them ideal for applications where maximum strength and rigidity are needed.

When selecting Z purlins for a construction project, it’s important to consider the load span tables and choose the best option for the job. By choosing the right purlin type for the job, you can ensure the safety and reliability of your structure.
