What is the Best Exposed Fastener for Metal Roofing?

Concealed fastener systems are a fantastic way to add value to your home. They can provide a clean aesthetic that makes your home look more appealing, and they can also help you save money on energy bills by reducing the amount of air infiltration in your home.

Concealed fasteners can also be used to reduce noise transmission and create a more soundproof environment inside your home. This is especially useful if you have young children who are trying to sleep or if you share walls with neighbors who like to listen to loud music at night.

Another benefit of concealed fasteners is that they allow for easier installation and maintenance of distinct types of materials throughout your home. This makes it easy for homeowners who do not have prior experience with construction projects or who do not have time for frequent repairs.

What are the specifications of wood purlins?

When you intend to attach metal panels with wood purlins, like 2” X 4”, a #9 fastener will provide a better pull-out in this matter. The specifications of wood purlins are as follows:

  • Purlin length is usually 3 meters long, and they can be cut to any length.
  • The width of the purlin depends on the span of the roof, but it is generally around 50mm. The thickness of wood purlins is around 10mm or 12mm.
  • Wood purlins are widely used in the construction industry. They are used to support ceiling joists and rafters, and they are often made from softwood. They are typically made to span about 16 feet, although there are some larger purlins available as well.
  • Wood purlins come in a variety of sizes, ranging from 2″ x 4″ to 6″ x 12″. They also vary in thickness based on the size of the purlin. The typical thickness is 1-1/2″, but you can find thicker or thinner purlins if desired.
  • Purlin length should be at least as long as the distance between the two walls that it crosses. This ensures that it won’t sag when installed properly.
  • The distance between posts (or columns) should be no more than 8 feet apart when installing wood purlins.

What is OSB/Plywood Decking used for?

When you are using Plywood decking instead of wood purlins, the change in the fastener will take place, and instead of using the #9 fastener, you will have to use #12. These fasteners have got specifications like 8 threads per inch, 212” diameter, and self-drills through steel up to 24 Ga. thick.

What is the disadvantage of using #12?

With a larger thread style along with a shank diameter, #12 becomes more costly than #9. When you are working on a big project, these minor calculations will become larger, and you might have to spend extra dollars on this type of fastener.

Summary

Not all of the exposed fasteners offer the same pull-out value. Education, especially in this field, matters a great deal. Instead of providing owners with information about cheap fasteners, the contractors must educate them about the best suitable fasteners that will be appropriate for their project.
