Chain Link Coating

Aluminized Vs. Galvanized: What’s the difference?

When choosing chain link fabric for guardrail and fencing projects, steel coating matters. Two of the most common coating types are aluminized and galvanized, but what is the difference? These two coatings deliver very different levels of performance in the field. As customers look for longer-lasting systems with lower lifetime costs, understanding these differences becomes essential.

This guide explains how aluminized and galvanized coatings compare, and why aluminized fabric is considered a superior product, and how it fits into our broader lineup of guardrail solutions.

Galvanized After Weave: The Standard Option

Galvanized chain link fabric is coated with molten zinc to protect the steel underneath. Most bleacher manufacturers utilize Galvanized After Weaving (GAW). It is widely used, cost effective, and familiar to most specifiers, but has a specific set of limitations...

Benefits:

• Affordable initial cost
• Readily available
• Provides basic corrosion resistance

Limitations:

• Coating can wear more quickly in environments with moisture, salt, or chemicals
• Prone to dulling, oxidation, and rust over time
• Shorter service life compared to aluminized coatings
• The galvanizing process (GAW) fully coats the steel, however it often results in a product having burrs or drips, which can lead to rough or sharp edges for spectators who may make contact with the uneven surface

Aluminized Steel: The Performance Upgrade

Aluminized chain link fabric uses a coating of aluminum rather than zinc. Aluminum naturally forms a protective barrier on its surface that resists corrosion, oxidation, and degradation.

So, what are the overall benefits?

1. Cleaner, Smoother Finish

The aluminized coating provides a more uniform finish than galvanization. It will not have burrs or drips, which creates a safer, smoother, and neater appearance. This makes aluminized fabric an excellent choice for schools, parks, and public spaces where both safety and presentation matter.

2. Longer Service Life

Aluminum coating offers significantly stronger resistance to corrosion. In many environments, aluminized chain link lasts one and a half to two times longer than standard galvanized chain link.

3. Improved Aesthetic Appeal

While galvanized fabric tends to fade and develop a chalky surface, aluminized maintains its visual appeal with brighter, shinier look for a longer period of time.

4. Low Maintenance

The durable aluminum coating resists chipping, cracking, and flaking. This reduces the need for ongoing repairs and maintenance, which lowers lifetime operating costs for property owners and municipalities.

Because of these performance advantages, aluminized chain link is commonly accepted as an equal or better substitute when galvanized chain link is listed in bid specifications.

Our Full Range of Guardrail and Fencing Options

Choosing the right chain link fabric is just one part of designing a long-lasting fencing system. Our product lineup includes:

• Aluminized Chain Link Fabric: Our recommended high-performance option for corrosion prone or long duration installations.
• Black Vinyl Coated Chain Link: Provides additional protection along with a modern, architectural appearance that is ideal for schools, parks, and commercial spaces.
• Vertical Picket Guardrail Systems: A premium solution that offers safety, visibility, and strong design appeal.

Why We Are Prioritizing Aluminized Chain Link

Aluminized chain link continues to prove itself as the best balance of durability, long term value, and visual appeal. It stands up to corrosion more effectively, requires less maintenance, and maintains a cleaner appearance over the lifetime of the installation. These advantages directly reduce long-term costs for owners, improve the quality of the finished project, and strengthen the reliability of the installations our dealers provide.

For these reasons, we are making aluminized chain link our recommended product moving forward. By emphasizing this higher performing option, we are helping contractors and customers achieve longer service life and better overall results with no increase in cost and with a stronger warranty behind it.

We remain committed to supplying guardrail and fencing solutions that last, perform, and deliver value. Aluminized chain link supports that commitment and reflects the direction we believe best serves our customers in the years ahead.
