Galvanized pipe hanger straps provide a practical, budget-friendly way to securely hang pipes. The zinc coating gives corrosion protection for indoor and outdoor applications. Galvanized steel offers strength to support piping while resisting rust and weathering. With so many types and sizes available, finding the right galvanized hanger strap or pipe suspension bracket for your project is straightforward.

What are Galvanized Pipe Hanger Straps?

Galvanized pipe hanger straps feature the same designs as standard carbon steel straps. The difference is that galvanized straps go through a zinc galvanization coating process. This applies a thin bonded zinc layer to the steel beneath.

The zinc acts as a sacrificial anode, protecting the base metal. When the zinc coating gets scratched or damaged, it will first oxidize and corrode before the exposed steel. This preserves and extends the life of the galvanized pipe clamp or strap.

Galvanization makes steel straps suitable for wet, humid, coastal, and chemical-exposed environments. It prevents rusting that could lead to ugly stains, drips, and eventual structural failure.

Galvanized pipe hangers provide a key component of pipe hanging systems and support:

  • Outdoor plumbing lines
  • Chemical and liquid transfer pipes
  • Electrical conduit runs
  • Commercial fire suppression piping
  • Utility lines in coastal regions

They provide strength, safety, and longevity in demanding settings. The stable zinc layer enables decades of reliable pipe support.

Sizing Galvanized Pipe Hanger Straps

Choosing the right galvanized pipe hanger strap size depends on:

Pipe Size & Schedule

Make sure the strap opening fits the outer diameter of the piping. Account for pipe schedule thickness variations.

Pipe Contents

The strap load capacity must handle the pipe contents weight per linear foot.

Structural Support Location

Measure attachment points to order threaded rods, plates, or brackets of proper lengths for your pipe hanging hardware.

Insulation Allowances

The clamp opening must leave room for any pipe insulation without compressing it.

Ambient Temperatures

Higher temperatures require reducing hanger spacing due to pipe expansion.

Take detailed measurements and consider all factors when selecting and ordering hangers. This ensures proper support and positioning for lasting performance.

Benefits of Galvanized Pipe Straps

Galvanized pipe hanger straps bring important advantages:

Corrosion Resistance

The thick zinc coating prevents rusting and oxidation, extending pipe system longevity.

Cost Effectiveness

Galvanized steel provides protection at a significantly lower cost than stainless steel strapping.

Strength & Durability

The underlying steel withstands considerable load capacities to support piping needs.

Electrical Grounding

Galvanized straps maintain continuous electrical ground bonding for safety.

Visually Appealing

Galvanized straps offer a clean, professional look for exposed piping.

Fire Resistance

Galvanization produces a finish resistant to fire damage or heat distortion.

Suitable for Extreme Environments

Galvanized hangers endure outdoor, chemical, coastal, and humid settings.

With so many strengths, it makes sense to choose galvanized pipe straps for reliable support and protection.

Galvanized Steel Pipe Hanger Limitations

While galvanized pipe straps serve well in many applications, they have some limitations to note:

  • Lower maximum temperature than stainless steel – approximately 500°F
  • Heavier than non-metallic strapping which becomes cumbersome for large systems
  • Not suitable for concentrated acidic or alkaline environments
  • Coating can be damaged by sharp impacts, leaving unprotected steel exposed
  • Carries rust staining risk if installation damages the protective layer
  • Zinc coating requires replacement every 15-20 years depending on use
  • More difficult to fully sterilize than plastic strap alternatives

Being aware of these potential downsides allows for better system planning and material decisions.

Additional Accessories for Galvanized Systems

Beyond galvanized pipe straps, accessories like fasteners, supports, and insulation shields ensure optimal installations:

  • Use galvanized bolts, nuts, washers, and threaded rod to prevent corrosion.
  • Floor flanges, wall brackets, and beam attachments anchor straps.
  • Riser clamps, clevis hangers, and U-bolts provide adjustable support.
  • Pipe guides maintain proper alignment and allow linear movement.
  • Rigid pipe shields at clamp contact points prevent compressed insulation.
  • Vibration dampeners reduce noise transfer and oscillations.
  • Safety cables provide secondary retention as needed by codes.

Take advantage of a wide accessory range to customize galvanized pipe hanging systems.

Choosing a Reputable Galvanized Pipe Hanger Manufacturer

Selecting the ideal galvanized pipe strap supplier involves:

Shopping by Pipe Size

Simplifies finding straps pre-sized for the piping used on the project.

Comparing Materials

Consider options like stainless steel for certain high-risk corrosion areas.

Reviewing Product Certifications

Look for reputable standards like MSS SP-58 compliance for quality assurance.

Validating Quality Processes

Ask about quality checks performed and sourcing specs.

Exploring Product Range

More diverse offerings provide a one-stop shop for all needs.

Researching Company History

Look for extensive industry experience supporting customers.

Examining Customer Reviews

Feedback from past clients indicates satisfaction and service.

Partnering with the right manufacturer ensures obtaining top-tier galvanized hangers tailored to the application.

Conclusion

Galvanized pipe hanger straps offer an affordable, low-maintenance means of safely and securely suspending pipe systems. When properly selected and installed, galvanized straps prevent sagging issues and pipe movement failures. Sizing components correctly, spacing hangers properly, and using compatible accessories improves performance. With the right galvanized hanger products protecting your piping infrastructure, you can have peace of mind knowing critical systems are supported for the long run.

Frequently Asked Questions

How long does galvanized coating last on pipe hangers?

Properly applied galvanized coating lasts 15-20 years on pipe hanger straps before reapplication is needed. Environmental factors affect longevity.

Can you use galvanized pipe hangers on plastic pipes?

Yes, galvanized hangers often support plastic piping. Avoid tight clamping that could distort softer pipe materials. Use shields to prevent surface damage.

What thickness of galvanizing is best?

For pipe hangers, a galvanized coating thickness of 2.0 to 4.0 mils provides optimal corrosion protection and cost balance. Thicker coatings up to 9 mils provide maximum longevity.

What spacing is required between galvanized pipe hangers?

12 feet is the maximum spacing between hangers for steel pipes under 2 inches in diameter. Reduce spacing for larger pipe sizes or follow manufacturer instructions.

Are galvanized pipe hangers suitable for fire sprinkler systems?

Yes, galvanized hangers meet NFPA 13 standards for fire sprinkler installations. Ensure hangers are FM Approved with proper UL classification.
