What are Perforated Metal Hanger Straps?

Perforated metal hanger straps, also known as perforated galvanized steel hanger straps, are durable and versatile metal straps designed to hang and support various components of your HVAC and plumbing systems. These straps are typically made from galvanized steel for added corrosion resistance and longevity.

One of the standout features of perforated metal hanger straps is their alternating holes or perforations. These holes allow for easy installation by nailing or screwing the straps to studs, joists, or other support structures at various lengths. This flexibility makes them suitable for a wide range of applications, from hanging insulated flexible ducts and round pipes to securing rectangular ductwork.

Applications of Perforated Metal Hanger Straps

Perforated metal hanger straps have a multitude of applications in both residential and commercial settings. Here are some common uses:

HVAC Systems: Hang insulated flexible ducts, round pipes, and rectangular ductwork from joists and rafters, ensuring proper support and preventing sagging.

Plumbing Systems: Support various pipe diameters, including CTS (Copper Tubing Size), IPS (Iron Pipe Size), and DWV (Drain, Waste, and Vent) pipes, while adhering to national codes for hanger spacing and slope requirements.

Electrical and Telecommunication: Secure conduits, cables, and wiring for electrical and telecommunication installations.

Industrial and Commercial: Hang and support piping, tubing, and ductwork in factories, warehouses, and other commercial buildings.

Benefits of Using Perforated Metal Hanger Straps

Investing in high-quality perforated metal hanger straps offers numerous benefits for your HVAC and plumbing systems:

Durability: Made from galvanized steel, these straps are built to withstand harsh environments, moisture, and temperature fluctuations, ensuring long-lasting performance.

Versatility: With their alternating hole design, perforated metal hanger straps can accommodate various pipe diameters and installation configurations, making them suitable for a wide range of projects.

Easy Installation: The pre-drilled pilot holes allow for quick and secure installation using nails or screws, saving you time and effort.

Code Compliance: When installed according to national codes and guidelines, perforated metal hanger straps help ensure your systems meet safety and performance standards.

Cost-Effective: Compared to custom-made or specialized hangers, perforated metal hanger straps offer an affordable and readily available solution for your support needs.

Choosing the Right Perforated Metal Hanger Strap

When selecting perforated metal hanger straps for your project, consider the following factors:

Material: Galvanized steel is the most common and durable choice, but other materials like copper or stainless steel may be preferred for specific applications or environments.

Width: Wider straps are generally recommended for heavier loads or larger pipe diameters. Common widths range from 1/2 inch to 1 inch.

Length: Perforated metal hanger straps are typically available in various lengths, such as 10 feet or 25 feet, allowing you to choose the most suitable option for your project.

Hole Spacing: The spacing between holes can vary, so consider the distance between your support structures and choose a strap with appropriate hole spacing for easy installation.

Installation Tips for Perforated Metal Hanger Straps

Proper installation is crucial for ensuring the effectiveness and safety of perforated metal hanger straps. Here are some tips to keep in mind:

Safety First: Always wear gloves and eye protection when handling and cutting metal hanger straps to prevent injuries.

Measure Twice, Cut Once: Carefully measure the required length of the strap before cutting to avoid waste and ensure a proper fit.

Secure Attachment: Use appropriate hardware, such as nails or screws, to securely fasten the straps to the support structures, following manufacturer recommendations and local building codes.

Adequate Support: Ensure that the support structures (joists, rafters, or studs) are capable of bearing the combined weight of the piping, ductwork, and the hanger straps.

Proper Spacing: Follow guidelines for hanger spacing based on the type and size of the pipes or ductwork being supported to prevent sagging or excessive stress.

Looping or Wrapping: Depending on the application, you may need to loop or double-wrap the strap around the pipe or ductwork for added support and stability.

Maintaining Your Perforated Metal Hanger Straps

While perforated metal hanger straps are designed for durability, proper maintenance can extend their lifespan and ensure optimal performance. Here are some maintenance tips:

Regular Inspections: Periodically inspect the straps for signs of corrosion, loosening, or damage, and replace them if necessary.

Tightening Hardware: Over time, the hardware (nails or screws) securing the straps may become loose. Regularly check and tighten them as needed.

Cleaning: For harsh environments or areas with excessive dust or debris, gently clean the straps and their surroundings to prevent buildup and potential corrosion.

Replacement: If a strap shows significant wear, corrosion, or damage, replace it promptly to maintain the integrity of your support system.


Perforated metal hanger straps are an essential component for properly supporting and securing your HVAC and plumbing systems. With their durability, versatility, and ease of installation, these straps offer a cost-effective and reliable solution for preventing sagging, ensuring code compliance, and prolonging the lifespan of your ductwork and piping.

By choosing high-quality perforated metal hanger straps and following proper installation and maintenance practices, you can have peace of mind knowing that your systems are well-supported and functioning efficiently. Invest in these versatile straps today and enjoy the benefits of a sturdy and long-lasting support system for years to come.
