Using Z Purlins In Roofing Applications

Jan 25, 2023 | Advice

When Should Purlins Be Used?

Purlins are typically used in roofing and construction applications when a strong and durable support structure is needed. They are used as the primary support structure for a roof, providing a strong and stable platform for the roofing material. They can be used in both residential and commercial buildings and can support a variety of roofing styles, such as gable, skillion, and curved roofs. Some common applications where purlins are used include:

Pre-Engineered Buildings

As the primary support structure for the roof and walls. They provide a stable platform for the building’s exterior and interior finishes.

Industrial Buildings

For instance, warehouses and factories, where a strong and durable support structure is required. They can support heavy loads, such as equipment and machinery, and withstand exposure to the elements, such as rain, snow, and strong winds.

Agricultural Buildings

Places such as barns, stables, and sheds, where they provide a strong and stable platform for the roofing material. They also provide a large open space underneath the roof, which is useful for storing equipment and feed.

Mezzanine Floors

These are intermediate floors that are located within a building. They provide a stable and secure platform for the mezzanine floor and the loads that it will carry.

Overall, purlins are used when a strong and durable support structure is needed for roofing and other building applications. They can be used in a variety of different types of buildings and provide a cost-effective and versatile solution for supporting the roof and walls.

What Is The Difference Between C Purlin And Z Purlin?

C purlins and Z purlins are both used as structural supports in construction and roofing applications, but they have some distinct differences. Firstly, and the main difference is their shape. C purlins are shaped like a “C” and have a curved top and bottom, while Z purlins are shaped like a “Z” and have a zigzag top and bottom.

Secondly, C purlins are generally stronger and more load-bearing than Z purlins. They can span greater distances and support more weight, making them suitable for use in larger and taller buildings. Lastly, C purlins tend to be more expensive than Z purlins, due to the greater span capability and load-bearing capacity.

In general, C purlins are better suited for larger and taller buildings, while Z purlins are more commonly used in smaller and lower-sloped roofing applications. Both C and Z purlins are made from high-strength steel, making them strong and durable. The choice of which one to use will depend on the specific requirements of the project and building.

What Size Do Z Purlins Come In?

Z purlins are available in a variety of sizes to suit different construction and roofing applications. The size of a Z purlin is determined by its depth, width, and thickness. The size of a Z purlin will depend on the specific requirements of the project and building. Larger, taller buildings will require larger and stronger purlins, while smaller buildings may only require smaller and lighter purlins. It is important to consult with a structural engineer or a professional contractor to determine the appropriate size.

What Are The Benefits Of Z Purlins?

Z purlins are used in roofing and construction applications because they offer several advantages over other types of roofing materials. Benefits include:

Strong & Durable

They are strong and durable enabling them to withstand heavy loads and extreme weather conditions, making them an ideal choice for roofing.

Versatile

They can be used across a range of applications as previously mentioned. For instance, residential, commercial, and industrial buildings. As well as across a variety of roofing styles, such as gable, skillion, and curved roofing.

Cost-Effective

Z purlins are relatively inexpensive compared to other roofing materials and require less labour to install. As well as having the ability to increase the energy efficiency of a building by providing a strong, insulated roof. This can help reduce heating and cooling costs.

Low Maintenance

Z purlins are low maintenance and require very little upkeep or repair over their lifespan.

Aesthetic Appeal

They can be painted or coated to match the colour and style of the building, making them an attractive and harmonious addition to any roofing design.

Long-lasting

They have a long lifespan and are able to withstand exposure to the elements, such as rain, snow, and strong winds, making them a long-lasting roofing solution.

Watertight

Z purlins are effective in keeping water out of the building, ensuring that the roof is watertight and protecting the building’s structure and contents.
