Perforated metal hanger straps are an essential component in numerous industries. Made from galvanized steel or stainless steel, these straps feature holes or slots along their length for easy fastening and adjustment. Their high tensile strength allows them to securely mount heavy pipes, conduits, ductwork, solar panels, and more. With simplicity, strength and flexibility, metal hanger straps provide endless versatility across infrastructure installations.

These perforated straps serve vital roles in construction, infrastructure, manufacturing plants, commercial buildings, and residential settings. Their effectiveness and ease of use make them a staple product for engineers, contractors, maintenance teams, and DIYers alike. As infrastructure demands intensify worldwide, metal hanger straps will only increase in popularity and innovation.

Heavy Duty Metal Strap with Holes

Galvanized or stainless steel hanger straps designed for heavy duty applications typically have thickness ranging from .023” to .105”. Bulkier straps are obviously built to bear more weight. But the material grade also factors in. G90 galvanized steel provides basic corrosion protection, while stainless steel offers maximized weather-resistance.

Heavy duty perforated straps work well securing:

  • Large hot and cold pipelines
  • Electrical cable trays and busway
  • Giant HVAC ductwork
  • Solar array frames
  • Support columns and racks
  • Commercial signage and lights

For outdoor installations, stainless steel delivers unmatched longevity. The perforations allow for flexible positioning not possible with custom brackets. In high temperature areas like power plants, thicker G90 straps withstand heat exposure better. Their strength and simplicity eases maintenance access for inspection and upgrades.

Metal Strapping for Framing

Hanger straps play a fundamental role in construction for framing wooden structures. Nailing perforated straps to joists and rafters enables heavy beams, columns and lintels to be securely mounted. This flexibility reduces complex fabricated brackets.

Strapping for framing uses lighter, thinner steel than other applications:

  • Hot-dipped galvanized coating prevents rust
  • Minimum .023” thickness supports vertical loads
  • Narrower 1⁄2”, 3⁄4”, 1” widths conserve material
  • Holes spaced 2” apart for nail fastening

Code compliant straps meet key criteria:

  • ASTM A653 specification grade 33+
  • Minimum G60 zinc coating
  • Printed product rating markings

Proper installation is crucial:

  • Use straps in parallel pairs for distribution
  • Place washers under bolt heads
  • Confirm adequate fastener sizing

How to Use Metal Hanger Straps

Installing perforated metal hanger straps involves this straightforward process:

Step 1) Determine needed load capacity and strap location/configuration

Step 2) Measure area and cut strap to required length with tin snips

Step 3) Position strap against mounting surface and mark hole locations

Step 4) Drill clearance holes for fasteners in mounting surface

Step 5) Secure strap through clearance holes with bolts/screws and washers

Step 6) Level item being hung and tighten fasteners

Follow this sequence for straightforward results:

  • Mark all hole locations before drilling
  • Use washers to prevent strap pull-through
  • Confirm torque specs for bolts/screws
  • Use multiple anchors for heavy loads

Safety is also imperative. Wear gloves and eye protection when cutting steel straps and drilling. Follow all product capacity, building codes and manufacturer instructions.

Applications: What Are Hanger Straps Used For?

The inherent versatility of perforated metal straps allows innovative use across countless sectors:

Construction: Securing HVAC, plumbing, conduits, ductwork, suspended grids, lighting, mechanical equipment, structural framing

Infrastructure: Mounting cable trays, industrial pipe runs, busway, solar panels, antennas, cameras, signs

Manufacturing: Hanging conveyors, robotic arms, assembly line components, ventilation

Energy: Nuclear/fossil fuel piping supports, cable runs, conduit brackets

Transportation: Suspending lighting, cameras, equipment in airports, train/subway stations, docks

Retail: Racking/shelving, security systems, wiring runs, HVAC supports

Residential: Mounting outdoor equipment, garage/basement piping, home theater setups

The list expands continually as engineers discover new applications for these strong, adaptable fasteners. Their simplicity allows builders of all skill levels to handle secure installations.

Galvanized Self-Fastening Hanger Strap

Galvanized self-fastening straps enhance traditional perforated strap benefits with notched teeth that grip firmly into wood without nails or screws. This unique design feature streamlines installing straps on wood studs and joists.

Brands like Simpson Strong-Tie produce self-fastening straps in various sizes and weight loads. Compared to ordinary straps, benefits include:

  • Faster mounting without separate fasteners
  • Firm grip into wood framing members
  • Allows for repositioning during install
  • Works on irregular or angled surfaces
  • Compatible with standard perforated straps

By sliding easily into position and locking firmly in place without extra steps, self-fastening straps simplify the hanging process while retaining extreme tensile strength.


Offering exceptional adaptability, strength and simplicity, perforated metal hanger straps provide endless value across infrastructure demands. These steel fasteners present the ultimate balancing act – flexibly addressing unique requirements with straightforward installation. Engineers continue finding new applications in existing and emerging sectors.

With advanced durability coatings and innovative self-fastening designs, metal straps grow more versatile and resilient each year. Their unmatched capabilities, ease of use and jobsite importance will only increase into the future. Whether building complex systems or basic home projects, metal hanger straps deliver reliable assistance.



Can metal hanger straps be used outside?

Yes. Galvanized and stainless straps resist corrosion in outdoor applications. Use additional paint/coatings as needed.

How are self-fastening straps installed?

Self-fastening straps lock into wood studs/joists simply by sliding into position. No need for extra nails or screws.

What’s the strongest metal for hanger straps?

Stainless steel rates strongest for weight load and weather-resistance. Grade 304 works for most applications.

Should I use tape/glue to reduce metal strap slippage?

Yes. Adhesive-backed foam or felt tape minimizes movement. Check product approvals.

Can metal straps touch nearby water or gas pipes?

Yes. But use protective tape on contact areas against corrosion or leakage.
