At ETAS, our metal purlins are commonly used in commercial and industrial buildings and in some residential metal roofs. Our metal purlins offer several advantages, including their lightweight yet sturdy nature, which makes them cost-effective and easy to handle during installation. Additionally, our metal purlins are durable and provide excellent structural support, allowing for greater design flexibility and the ability to span long distances without the need for supporting columns or beams.
Types of Metal Purlins
CEE Purlin
CEE Purlins play a crucial role in providing essential structural support for beams and metal panels used in walls and flooring. They are widely utilized for reinforcing walls and serving as floor joists. One of their notable advantages lies in their remarkable ability to span considerable lengths, making them ideal for various construction builds.
This style of steel purlin offers exceptional durability, contributing to the overall stability and longevity of the structures they support.
ZEE Purlins
ZEE Purlins play a vital role in constructing shell structures, or pre-engineered metal buildings, serving as horizontal beams for roof and wall joists. Their ability to provide superior strength and durability makes them a popular choice for large-scale structures.
Metal Purlin Finishes
Red Oxide Purlin
Red oxide metal purlins feature a thin, red oxide coating applied to the surface. This coating serves as a protective measure to help prevent rust formation during transportation and storage.
Despite its rust-preventive function, the red oxide coating is not intended for prolonged outdoor exposure, and additional protective measures or a final coat of paint may be required to maintain the purlins’ appearance and durability over time. Red oxide purlins are ideal if you are looking for a less expensive option, and the purlins are not exposed to weather elements.
Galvanized Metal Purlins
Galvanized metal purlins are an excellent choice for construction projects requiring maximum durability and corrosion resistance. The galvanization process involves applying zinc-alloy plating to the metal, creating a protective barrier against corrosion. This makes galvanized purlins ideal for harsh environments, such as chemical plants or coastal areas, where exposure to saltwater would otherwise lead to rusting in unfinished steel.
While galvanized steel is not entirely immune to oxidation and may develop white rust when exposed to moisture, it still outperforms non-galvanized alternatives in longevity and resilience.
Purlin Sizes
Metal purlin sizes are diverse and versatile, catering to a range of construction needs.These essential building components are offered in various dimensions, ranging from 4” to 14” web sizes and are available in 12, 14, and 16 gauge. The selection of sizes allows for flexibility in accommodating different structural requirements. Additionally, they are available in multiple finishes, including red oxide, gray, and galvanized, allowing you to choose the most suitable purlins for your projects.
