Wood Purlins for Metal Roof Systems and Their Benefits

Wood purlins for metal roof systems are a game-changer for builders and homeowners alike. They provide a cost-effective and efficient way to support metal roofing panels, reducing the need for expensive structural upgrades.

Wood purlins can be spaced up to 24 inches on center, which is significantly wider than traditional wood rafters. This allows for greater flexibility and more design options for metal roof systems.

By using wood purlins, builders can reduce labor costs and construction time, as well as minimize waste and environmental impact. This makes wood purlins a more sustainable choice for metal roof systems.

Wood purlins for metal roofs are a crucial component in creating a sturdy and weather-tight structure. They provide additional support to the metal roofing panels, ensuring the roof can withstand various weather conditions.

A typical wood purlin can range from 2x4 to 2x8 in size, depending on the design and load requirements of the roof. The most common type of wood used for purlins is pressure-treated southern yellow pine.

Wood purlins can be installed at various spacings, but a general rule of thumb is to space them 24 inches on center, or O.C.

When choosing a substrate for your metal roofing system, you have two main options: open framing and solid substrates.

Open framing is a common choice that uses wood or metal framing members to secure the metal roof panels. These members can be individual pieces of wood, formed steel, or truss-like members built from multiple pieces.

The weight and span of the open area must be supported by the structural-style panels used in open framing substrates.

Open framing substrates are a good option for metal roofing systems that require a high level of structural support.

The two main types of solid substrates are composite and plywood.

Composite substrates are a cost-effective option that can be used in place of plywood.

The product is specifically designed for certain types of roofs, including 7/8″ and 3/4″ high x 2.67” rib-pitch U.S. corrugated metal roofs.

It fastens through the roof panel and into the structure, providing a secure hold.

The reservoir conceals the sealant from UV exposure, preventing UV degradation and over-compression of the sealant.

This design helps to protect the sealant from the elements and ensures a long-lasting seal.

When choosing a CorruBracket, consider its unique fastening method that secures the bracket in the low or between the ribs of the metal roof, through the deck into the structure.

This allows for a rib pitch of +/- 2.67” (68 mm), making it a versatile option for various roof profiles.

The CorruBracket's design ensures a secure hold, but it's essential to select the right fastener to match its capabilities.

To determine the lineal footage of huggers you need, use a simple formula that involves dividing the width of the slope by the spacing of the existing purlins, adding 1 for the eave strut, and then multiplying by the length of the eave.

For mono slope buildings, you're all set with the calculation.

The CorruBracket is a popular choice for roof profiles, but is it the best fit for your specific needs? It fastens in the low point of the rib or between the ribs, providing a secure hold on the deck.

This unique fastening method allows the CorruBracket to accommodate a rib pitch of +/- 2.67” (68 mm). That's a pretty significant range.

The CorruBracket's ability to handle varying rib pitches makes it a versatile option for different roof profiles.
