Types of Joist Hangers – The Ultimate Guide

The importance of proper bracing cannot be overstated when it comes to building a strong, reliable frame for your building or deck project. One critical component in this support system is the joist hanger. Whether you’re building a deck, a floor system, or a ceiling, joist hangers play a key role in ensuring your structure is both secure and durable. In this ultimate guide, we’ll walk you through everything you need to know about joist hangers, from what they are to how to choose the right type and install them correctly. I hope the following content will help you.

 

What is a Joist Hanger?

A joist hanger is a wood connector metal joist bracket designed to provide a secure connection between a joist (horizontal support beam) and a supporting structure such as a ledger board, wall, or beam. They are commonly used in both residential and commercial construction to keep joists properly aligned and secure while helping to distribute the weight of the structure evenly. Joist hangers are usually made of galvanized steel or stainless steel, which is corrosion-resistant. We can provide you with a variety of designs and sizes to meet your different market application needs.

Different Types of Joist Hangers

Joist hangers come in various styles, each designed for different structural needs and applications. Here are the main types of joist hangers:

1. Face-Mount Joist Hangers

The most common type, face-mount joist hangers, are attached to the face of the supporting beam or ledger board. This type is ideal for most residential applications, especially when the joist is positioned perpendicular to the supporting structure.

2. Top-Mount Joist Hangers

These hangers are mounted on top of the supporting beam, making them useful when the joists need to rest on top of a ledger board, rather than hang off it. Top-mount joist hangers are often used in framing for floor systems and ceilings.

3. Heavy-Duty Joist Hangers

In situations where there’s more weight or larger loads to bear, heavy-duty joist hangers are essential. These are constructed from thicker gauge steel and are designed for use in commercial buildings or larger residential projects, providing extra strength and support.

4. Adjustable Joist Hangers

Adjustable joist hangers offer flexibility, as they can be adjusted to fit joists of various widths. This makes them a great option for projects that require precise placement of the joists, especially in renovation or retrofit situations.

5. Flanged Joist Hangers

This type of hanger includes a flange on the side that helps to further secure the joist. It is typically used when extra stability is needed, particularly in high-stress areas of the building, like the perimeter of a deck.

 

Joist Hanger Load Capacity

When choosing a joist hanger, it’s important to consider the expected load it will carry, which is typically determined by the size of the joist and the weight it will support. Buildings-hardware Manufacturers provide specifications for each type of hanger, including load-bearing capacity, so you can select the appropriate hanger based on your project’s requirements.

Be sure to factor in the type of materials you’re using (wood, steel, etc.) and the span of the joists when determining load capacity. If in doubt, it’s always best to choose a hanger with a higher load capacity to ensure the safety and stability of your structure.

 

How to Install Joist Hangers?

Installing joist hangers is a relatively straightforward process, but it requires some precision to ensure that everything is properly aligned and secure. Here’s a step-by-step guide for installing joist hangers:

Step 1. Nail the Joists to the Beams

Use galvanized nails to nail the deck joists into position on the wall beams. Make sure the top of the joists is flush with the top of the flashing on the wall beams so that the deck lays evenly. Use hot-dip galvanized nails for exterior work and regular (non-countersunk) nails for interior work. Start nailing the joists before you put them in place and hammer them in.

Step 2. Set the Beam Hangers

Squeeze the joist hangers tightly around the joists and drive the speed forks into the beam boards to temporarily hold the joists in place. Make sure the joists are upright in the joist hangers with no gaps next to and under the joists.

Step 3. Nail to the Beams First

Use galvanized nails to secure the joist hangers to the wall beams outdoors. To allow the joist hangers to perform to their rated load capacity, fill all holes in the joist flanges with nails specified by the beam hanger manufacturer.

Step 4. Nail the Joists – Double Shear Hangers

For double shear joist hangers, drive four galvanized nails at 45-degree angles through the beam hanger, through the joist, and into the ledger board.

Step 5. Nail the Joists – Standard Hangers

For standard joist hangers, use only galvanized joist hanger nails to secure the hanger to the joist. Avoid using longer nails that will pierce the joist and come out the other side of the hanger.

Step 6. Check Alignment and Stability

Finally, check to make sure the joists are properly aligned and that the hangers are securely held to the joists. If needed, make adjustments to ensure everything is level and stable.

 

Tips for Ensuring a Strong Connection the Joist Hangers

- Use the correct fasteners: Always use nails or screws suitable for exterior use, such as galvanized or stainless steel fasteners, to avoid rust and ensure long-lasting performance.

- Pre-drill Holes in Joists: To prevent splitting, pre-drill pilot holes in your joists before attaching them to the joist hangers.

- Double-Check the Load Capacity: Make sure the joist hangers you select are appropriate for the load they will carry, taking into account the span and weight of the structure.

- Consider Using Hurricane Clips: In areas prone to high winds, consider using hurricane clips along with joist hangers for added stability and resistance against lifting forces.

 

Where to Buy Joist Hangers?

If you are purchasing your own joist hangers, you can do so at your local hardware store, lumberyard, or online. If you are a dealer or have a large project that requires joist hangers in bulk, buying wholesale from Building-hardware is a great option to reduce costs.

FAQ

 

What are the Uses of Joist Hangers?

Joist hangers are used to securely fasten joists (horizontal support beams) to another structural element, such as a ledger board or support beam. It distribute the weight of the structure evenly, preventing the joist from sagging or shifting.

 

What Types of Materials are Joist Hangers Made of?

Joist hangers are typically made of galvanized steel, stainless steel, and sometimes coated with an anti-corrosion coating. Because of their durability, strength, and resistance to rust, especially in outdoor applications such as decks.

 

Can I Use Joist Hangers for Both Wood and Steel Joists?

Yes, joist hangers can be used for both wood and steel joists. However, it is critical to choose the right type of hanger designed for the specific material you are working with to ensure a secure and stable connection.

 

Can I Use Joist Hangers for Ceiling Joists?

Yes, joist hangers are commonly used for both ceiling and floor joists. They are versatile and can be used in a variety of applications where horizontal beams need to be securely fastened to a vertical support.

 

Are Joist Hangers Adjustable?

Yes, adjustable joist hangers are available and can be used in situations where the width of the joists may vary. These hangers provide flexibility, allowing you to adjust the position of the joist to fit specific needs.

 

Do Need to Use Joist Hangers for Every Joist in My Structure?

Typically, joist hangers are used where the joists meet a supporting structure, like a beam or ledger board. If a joist is connected to another joist (e.g., in a continuous beam setup), you may not need a hanger. However, it’s always best to use joist hangers at critical load-bearing points to ensure the strength of the structure.

 

Can Reuse Joist Hangers?

While joist hangers can technically be reused, it’s not recommended if they’ve been in use for an extended period or have been exposed to significant loads. Reused hangers may have weakened or deformed, compromising their strength. It’s often best to use new hangers for each installation to ensure safety and stability.
