Understanding Welded Wire Fence and Wood Posts
Before you even pick up a tool, it’s crucial to understand the materials you’re working with. Knowing the characteristics of welded wire fence and different wood posts will help you make informed decisions throughout your project. Welded wire fence is a versatile and popular choice for many applications.
It consists of individual steel wires welded together at each intersection, forming a grid pattern.
This construction makes it rigid and strong, unlike woven wire which can be more flexible.
Types of Welded Wire Fence
There are several variations of welded wire fence, each suited for different purposes:
- Standard Galvanized: This is the most common type, offering good rust resistance. The wire is coated with zinc after welding.
- PVC-Coated: Features a layer of PVC plastic over the galvanized wire. This provides superior rust protection, a smoother finish, and often comes in green or black, blending better with landscapes. It’s ideal for pet enclosures or garden fencing where aesthetics matter.
- Heavy-Gauge vs. Light-Gauge: Gauge refers to the wire thickness. A lower gauge number means thicker, stronger wire. Heavy-gauge wire (e.g., 12.5 gauge) is best for containing larger animals or high-impact areas, while lighter gauges (e.g., 16 gauge) are suitable for garden barriers.
- Mesh Size: This is the size of the openings in the grid. Common sizes include 2×4 inches, 2×2 inches, or even 1×2 inches. Smaller mesh sizes are excellent for keeping out smaller pests or containing small pets.
Choosing the Right Wood Posts
Your posts are the backbone of your fence, so selecting the correct type and size is paramount. Pressure-treated lumber is the go-to choice for fence posts.
It’s chemically treated to resist rot, insects, and fungal decay, making it suitable for direct ground contact.
Look for posts rated for “ground contact” or “below ground.” Cedar or Redwood posts are naturally rot-resistant but are typically more expensive.
They offer a beautiful, natural aesthetic if that’s a priority for your project.
For post size, 4×4 inch posts are standard for most residential fences.
Corner and gate posts, which bear more tension and stress, often benefit from 6×6 inch posts for added stability.
Line posts can sometimes be 2x4s or smaller round posts, depending on the fence height and required strength.
Essential Tools and Materials for Fence Installation
Having the right tools and materials at hand makes all the difference in a smooth and efficient installation. Don’t skimp on quality; good tools not only make the job easier but also safer and produce better results.
Must-Have Tools
- Heavy-Duty Fencing Pliers: These are specialized pliers with multiple functions, including cutting wire, pulling staples, and hammering. An absolute essential.
- Wire Cutters: For precise cuts, especially on heavier gauge wire.
- Hammer or Staple Gun: A good claw hammer is fine for driving staples. For larger projects, a pneumatic or manual staple gun designed for fencing can save a lot of time and effort.
- Tape Measure: For accurate spacing of posts and measuring fence sections.
- Level: To ensure your posts are plumb (perfectly vertical).
- Post Hole Digger or Auger: For digging post holes. A hand-operated post hole digger is fine for a few holes, but an auger (manual or powered) is a back-saver for many posts.
- String Line and Stakes: For laying out your fence line straight and true.
- Work Gloves: Heavy-duty gloves are crucial to protect your hands from sharp wire ends and splinters.
- Safety Glasses: Always wear eye protection when cutting or hammering.
- Utility Knife: For cutting any ties or packaging.
- Tension Bar/Stretcher Bar (Optional but Recommended): For achieving proper tension on longer fence runs.
- Come-Along or Ratchet Straps (Optional): For tensioning fence, especially at corners.
Materials You’ll Need
- Welded Wire Fence: Purchase the correct height, length, gauge, and mesh size for your project.
- Wood Fence Posts: Pressure-treated 4x4s or 6x6s for corners/ends, and 4x4s for line posts.
- Galvanized Fence Staples (U-Nails): These are U-shaped fasteners specifically designed for securing wire to wood. Choose staples that are long enough (1.5 to 2 inches) to penetrate the post well, but not so long they risk splitting it.
- Concrete Mix (Optional): For setting posts in the ground, especially corner and gate posts, for maximum stability.
- Gravel: For drainage at the bottom of post holes.
- Post Caps (Optional): To protect the tops of your wood posts from weathering.
Prepping Your Wood Posts and Fence Line
Proper preparation is the foundation of a successful fence. Don’t rush this stage; careful planning now will prevent headaches later.
Laying Out Your Fence Line
Start by marking your fence line with stakes and a string.
This ensures your fence runs straight and accurately.
Measure and mark the locations for all your posts: corners, ends, gates, and line posts.
For line posts, aim for spacing typically between 6 to 10 feet, depending on the fence height and the terrain.
Closer spacing provides more rigidity and prevents sagging.
Digging Post Holes
Dig holes for your posts that are deep enough to provide stability.
A good rule of thumb is to bury one-third of the post’s total length.
For example, a 6-foot tall fence will need an 8-foot post, with 2 feet buried.
Make the holes about three times the width of your post.
So, for a 4×4 post, a 12-inch diameter hole is appropriate.
Add 4-6 inches of gravel at the bottom of each hole for drainage.
This prevents water from pooling around the post and accelerating rot.
Setting Your Posts
Place your posts in the holes, ensuring they are plumb using a level.
For stability, especially for corner and end posts, it’s highly recommended to set them in concrete.
Mix the concrete according to the manufacturer’s instructions and pour it around the post.
Slope the top of the concrete away from the post to shed water.
For line posts, you can tamp dirt firmly around them in layers, wetting each layer to aid compaction.
Allow concrete to cure fully (usually 24-48 hours) before attaching any fence material.
Step-by-Step: how to attach welded wire fence to wood post securely
Now for the main event! This section will guide you through the process of how to attach welded wire fence to wood post, ensuring a strong and lasting connection. Remember to always work safely, wearing gloves and eye protection.
1. Starting at a Corner or End Post
The corner or end posts are your anchor points.
These posts will bear the most tension, so ensure they are extremely stable.
Unroll a section of your welded wire fence, aligning the bottom edge with your desired height from the ground.
Often, a 2-4 inch gap at the bottom helps with drainage and prevents debris buildup.
Hold the fence firmly against the side of the post.
Using your fencing pliers or hammer, drive the first few galvanized fence staples into the post.
Start with one staple at the top, one in the middle, and one at the bottom.
Drive the staples almost all the way in, but leave a tiny bit of space so they don’t pinch the wire too tightly, allowing for slight movement due to expansion and contraction.
For corner posts, you’ll eventually wrap the fence around or cut it and start a new section.
2. Attaching to Intermediate Line Posts
With the fence anchored at one end, unroll it along your fence line to the next post.
Align the fence to the correct height.
You’ll need to apply some tension to the fence as you move from post to post.
For shorter runs (under 50 feet), you might be able to manually pull the fence taut.
For longer runs, consider using a tension bar or a come-along with a stretcher bar.
Attach the tension bar vertically to the fence about a foot or two from the post, then use the come-along to pull the fence towards the post.
Once taut, secure the fence to the line post using fence staples.
Place staples every 6-12 inches vertically along the post, ensuring each strand of horizontal wire is secured or at least every other strand.
Drive staples at a slight angle to increase their holding power.
3. Reaching the Next Corner or End Post
As you approach the next corner or end post, apply significant tension.
This is where a tension bar and come-along are invaluable.
Attach the tension bar to the fence, then use the come-along to pull the fence until it is taut but not overstretched, which could damage the welds.
You’re looking for a firm, even tension across the entire height of the fence.
Once the desired tension is achieved, secure the fence to the post with plenty of staples, just as you did at the starting post.
You can also wrap the end of the wire around the post and secure it back to itself with wire ties for extra strength.
4. Joining Sections of Welded Wire Fence
If your fence run is longer than a single roll of wire, you’ll need to join sections.
Overlap the ends of the two fence sections by at least 6-12 inches.
Use heavy-duty hog rings or specialized fence clips to securely fasten the overlapping wires together.
Space these fasteners every few inches vertically and horizontally to create a strong, seamless connection.
Alternatively, you can cut one section precisely at a post and start the new section on the same post, treating it like a new end post attachment.
Achieving Proper Tension and Preventing Sagging
Proper tensioning is critical for a professional-looking and effective fence. A saggy fence is not only unsightly but also less effective at containing or excluding animals.
Techniques for Tensioning
Manual Pulling (Short Runs): For short fence runs (under 50 feet), you might be able to pull the fence taut by hand.
Have a helper hold one end while you pull and staple at the next post.
Use your body weight and leverage. Tension Bar and Come-Along: This is the most effective method for longer runs.
A tension bar is a piece of steel or wood that you weave through the fence mesh near the end of a section.
Then, attach a come-along (a hand-operated winch) to the tension bar and hook it to the post.
Crank the come-along to gradually pull the fence taut. Stretcher Bar and Clamp: Similar to a tension bar, a stretcher bar is clamped onto the fence.
A come-along or ratchet strap is then used to pull the bar towards the post, tensioning the fence.
Preventing Sagging Between Posts
Even with good tension at the ends, welded wire fence can sag slightly between line posts, especially with wider post spacing.
To counteract this, consider adding a “top wire” or “tension wire.”
Run a heavy-gauge wire (e.g., 9-gauge) along the top of your fence, just above the welded wire.
Attach this tension wire to the posts using staples and then secure the welded wire fence to this tension wire with smaller wire ties or hog rings every few feet.
This provides an additional horizontal support, helping to keep the top edge straight and prevent the welded wire from slumping.
For very long runs or heavy-duty applications, a mid-span tension wire can also be added.
Finishing Touches and Maintenance Tips
Once your fence is up, a few finishing touches and regular maintenance will ensure it lasts for years to come.
Trimming Excess Wire
After all sections are securely stapled, use your wire cutters to trim any excess wire.
Be careful to cut flush with the post or fold sharp ends away to prevent injury.
Walk the fence line and snip off any loose strands or sharp edges.
Post Caps and Protectors
Consider adding decorative or protective post caps to the top of your wood posts.
These caps shield the end grain of the wood from rain and sun, significantly extending the life of your posts.
They also add a finished, professional look to your fence.
Regular Maintenance
Inspect Annually: Walk your fence line at least once a year.
Look for loose staples, damaged wire, or leaning posts. Repair Promptly: Re-drive any loose staples or add new ones.
If a section of wire is damaged, patch it with a new piece of welded wire and hog rings or replace the entire section if necessary. Clear Vegetation: Keep weeds and vines from growing on or through your fence.
Vegetation can hold moisture against the wire, promoting rust, and can also put undue stress on the fence structure. Check Post Stability: Ensure posts remain plumb and secure.
If a post starts to loosen, you might need to re-tamp soil around it or add more concrete.
Troubleshooting Common Welded Wire Fence Issues
Even with the best planning, issues can arise. Knowing how to address common problems will save you time and frustration.
Fence Sagging After Installation
If your fence starts to sag shortly after installation, it’s usually due to insufficient tension during the initial setup.
You’ll need to re-tension the section.
Remove staples from the end post, re-stretch the fence using a tension bar and come-along, and then re-secure it.
Consider adding a top tension wire for extra support, as discussed earlier.
Posts Leaning or Loosening
Leaning posts indicate improper installation or soil conditions.
If posts weren’t buried deep enough or didn’t have adequate concrete/tamping, they can shift.
For minor leans, you might be able to straighten the post and re-tamp soil firmly around it, ensuring good drainage.
For significant leaning, especially at corner posts, you may need to dig out the post, reinforce the hole, and reset it with proper concrete.
Rusting Wire
While galvanized wire is rust-resistant, it’s not rust-proof, especially if the coating is scratched or damaged.
If you see small spots of rust, you can try cleaning them with a wire brush and applying a rust-inhibiting primer and paint designed for metal.
For extensive rust, consider replacing the section of fence.
Next time, opt for PVC-coated welded wire fence for superior rust protection.
Animals Pushing Under or Over the Fence
If animals are getting through, your fence might not be high enough or buried deep enough.
For digging animals, consider burying the bottom edge of the fence 6-12 inches into the ground.
You can also bend the bottom 6 inches of the fence outwards (an L-footer) and bury it horizontally to deter digging.
For jumping or climbing animals, you might need to extend the height of your fence or add a deterrent like an outward-sloping top section (often used for cat enclosures).
Frequently Asked Questions About Attaching Welded Wire Fence
What’s the best way to secure welded wire fence to wood posts for long-term durability?
The best method involves using galvanized fence staples (U-nails) that are long enough (1.5 to 2 inches) to penetrate the post well. Drive them firmly but not so tight that they pinch the wire, allowing for slight movement. For critical anchor points like corner posts, consider doubling up on staples or using a combination of staples and wire ties for extra security. Proper tensioning is also key to durability.
Can I use screws or nails instead of fence staples?
While you can use screws with washers or roofing nails, fence staples are specifically designed for this purpose. Their U-shape cradles the wire without crimping it, and they have excellent holding power against the pulling forces of a tensioned fence. Screws and nails can pinch and damage the wire, potentially leading to rust or breakage over time. Staples are generally the superior choice.
How far apart should fence staples be placed on wood posts?
For line posts, aim to place staples every 6 to 12 inches vertically, ensuring at least every other horizontal wire strand is secured. At corner and end posts, which bear the most tension, you should place staples much closer, often every 2-4 inches, to provide maximum grip and prevent the fence from pulling away.
Do I need to stretch welded wire fence, or can I just staple it?
Yes, you absolutely need to stretch welded wire fence, especially for runs longer than a few feet. Without proper tension, the fence will sag between posts, look unprofessional, and be less effective as a barrier. Using a tension bar and come-along is the most effective way to achieve even, taut tension across the entire fence line.
What if my ground isn’t level? How do I attach welded wire fence to wood post then?
If your ground is uneven, you have a couple of options. You can “step” the fence, meaning each section between posts follows a level line, and then the fence drops down at the post to meet the next level section. This creates a stepped appearance. Alternatively, you can “follow the contour” of the ground, which means the bottom of your fence will rise and fall with the terrain. This can be more challenging to tension evenly and may leave larger gaps at low points that animals could exploit. Stepping is often preferred for a cleaner look and better security.
