Stability Comes from Quality Cast Parts

Is your dock actually built for long-lasting stability?

Many dock parts are stamped or extruded. The problem with these parts is that they tend to bend, slip, or break; this causes instability, especially with bottom plates and crossarm clamps. Alumi-Span uses cast parts, which don’t flex over time like stamped or extruded parts. Using cast parts for your dock eliminates a big instability issue.

Why the Lakebed Matters

The bottom of the post has to sit on something solid. On firm sand or gravel, a post can sit directly on the bottom plates. But on soft, mucky, or silty bottoms, you need more bearing surface. That's where permanent dock bases come in.

• Permanent augers screw into the bottom like a giant corkscrew, anchoring the post in place so it can't shift, even in soft sediment or current.
• Mud boards spread the post's weight over a wider footprint, so the post doesn't sink into soft bottom over time.

For a dock you plan to leave in year-round, an anchored base is worth the extra effort. For seasonal docks, a mud board or well-seated post can be plenty; the key is knowing what your bottom is made of before you set the first section.

Need to Know how to Build a Boat Dock?

Alumi-Span has been building docks since 1956, and we sell everything down to the nuts and bolts, so you can upgrade your existing dock piece by piece instead of starting over.  

If you need instructions on how to build a boat dock, or if you’re just not sure what your dock needs, give us a call at 855-523-2444 or click here to submit a contact form — we’re more than happy to help you match the right parts to your dock.

Stability Starts Below the Deck

Does your dock feel loose or unstable?

Every dock section you walk on transfers its weight to a handful of support points: the posts. Those posts carry the load down to the lakebed, and the crossarms spread the load between them so no single post is doing all the work. When this system is sound, your dock stays level and doesn't bounce or sway underfoot. When it isn't, you feel it in every step — and over time, a wobbly dock puts stress on the connections and deck sections a
bove it.

The good news: you don't have to replace the whole dock to fix the problem. Most stability issues are solved at the support level.

Start with the Right Posts

Posts are the backbone of the dock, so size matters. Alumi-Span's standard is 2" OD aluminum dock posts, which they recommend for all new applications. They're lighter and last longer than the older 1.9" OD posts found on many existing docks. If you're building new, go with 2". If you're retrofitting an older dock, measure carefully before ordering, because the two sizes don't mix.

Aluminum posts are the best choice for a few reasons: they won't rot like wood, they resist corrosion better than steel, and they are lighter for pulling in and out season after season. Many Alumi-Span docks are still in service after more than 50 years, and that longevity starts with the posts.

Don't Forget the Crossarms

Posts hold the dock up, but crossarms and platform trusses hold the posts together. They tie adjacent posts into a rigid frame, which is what keeps the whole structure from racking or twisting when a wave hits or when someone steps on the edge of the deck. If your dock has always felt a little "loose," missing or undersized crossarms are often the culprit.

Long-Term Value

In our last blog, we discussed how the materials used to build your dock contribute directly to safety
and durability. But they do even more than that! In this blog, we’ll discuss how high-quality materials contribute to lower maintenance and long-term value.

Low Maintenance, More Enjoyment

Traditional materials like wood often require:

• Regular sealing or staining 
• Repairs from rot or insect damage 
• Board replacements over time 

In contrast, high-quality materials such as aluminum and vinyl require little to no ongoing maintenance. They don’t need painting, sealing, or frequent repairs—just occasional cleaning to keep them looking their best. 

That means enjoying more time on the water and less time working on your dock.

Long-Term Value Over Upfront Cost

It’s tempting to focus on initial price when choosing a dock. But the real cost of a dock includes:

• Maintenance over time 
• Repairs and part replacements 
• Lifespan of the structure 

Lower-quality materials might save money upfront, but they often lead to higher costs down the road.

Investing in premium materials delivers:

• Longer lifespan 
• Reduced maintenance expenses 
• Greater reliability 

In other words, you’re not just buying a dock, you’re making a long-term investment in your waterfront property.

When it comes to aluminum dock manufacturing, materials aren’t just a detail—they’re the foundation of everything.

High-quality materials provide:

• Strength and durability 
• Safety and stability 
• Low maintenance 
• Long-term value 

At the end of the day, a well-built dock should give you peace of mind every time you step onto it.

Durability and Safety

Did you know that what your dock is made of makes a big difference?

The materials used contribute directly to the safety and durability of your dock. Here’s how:

Durability: Built to Withstand the Elements

One of the biggest advantages of premium dock materials is long-term durability.

For example, anodized aluminum is widely recognized for its ability to resist rust, corrosion, and rot—common issues that affect traditional materials like wood. Unlike wood, which can absorb moisture and deteriorate over time, aluminum maintains its structural integrity even in harsh waterfront environments. 

In fact, well-built aluminum docks can last over 50 years with minimal degradation, while wood docks often require significant upkeep and may only last 10–20 years depending on conditions. 

Safety

High-quality materials contribute directly to:

• Structural stability under heavy use 
• Slip resistance in wet conditions 
• Consistent performance over time 

Inferior materials can lead to issues like splintering, warping, or weakened joints—all of which increase the risk of accidents.

By choosing durable, well-engineered materials, you’re not just improving your dock—you’re protecting your family, your guests, and your equipment.

Anodized Aluminum vs. Other Dock Materials - How Do They Compare?

When building or replacing a dock, the material you choose impacts everything: maintenance,
durability, and long-term value. Here’s how anodized aluminum compares to the most common options.

Anodized Aluminum vs. Wood

Wood offers a classic and natural look, but it comes with ongoing upkeep. Regular staining, sealing, and inspections are needed to prevent rot, splintering, and insect damage. Over time, boards can warp, fasteners loosen, and structural integrity declines.

Anodized aluminum eliminates those concerns. It won’t rot, splinter, or attract insects, and it doesn’t require seasonal treatments. For long-term performance without yearly maintenance, it’s the more practical choice.

Anodized Aluminum vs. Standard Aluminum

Not all aluminum docks perform the same. Standard (mill-finish) aluminum can discolor, develop surface pitting, and take on a chalky appearance over time (especially in humid environments). It may also leave residue on surfaces it contacts.

Anodized aluminum solves these issues by creating a harder, more stable surface that resists corrosion, discoloration, and wear. The result is a dock that maintains both its appearance and performance far longer.

Anodized Aluminum vs. Vinyl

Vinyl is lightweight and low-maintenance, but it has notable limitations. It can become uncomfortably hot in direct sunlight and may be more prone to surface damage under heavy use.

Anodized aluminum stays cooler all summer long, offers greater surface durability, and provides the structural strength needed for larger or more demanding dock setups.

The Verdict

Each material has its place, depending on budget and preference. But when the goal is long-term durability, minimal maintenance, and consistent performance, anodized aluminum stands out as the stronger overall investment.

What Makes Anodized Aluminum the Best Material for Your Dock?

Choosing the right dock material can mean the difference between constant upkeep and decades of
reliable use. Anodized aluminum stands out as a long-term solution built for real waterfront conditions.

It’s Built into the Metal

Anodizing isn’t a coating; it’s a process that transforms the surface of aluminum into a harder, more durable layer. Because it becomes part of the metal, it won’t chip, peel, or wear away over time.

Superior Corrosion Resistance

In waterfront environments, untreated aluminum can discolor and develop surface damage over time. Anodized aluminum creates a protective barrier that helps prevent moisture and environmental wear, keeping your dock looking and performing better for longer.

Low Maintenance

Wood docks require frequent sealing and repairs, and standard aluminum docks can also require upkeep over time. Anodized aluminum docks keep things simple. Rinsing your dock with fresh water is typically all it takes to maintain its appearance and performance.

Built to Last and Looks Great Doing It 

Anodized aluminum resists fading, darkening, and uneven wear, maintaining a clean, consistent appearance over time. It’s a material designed to deliver long-term performance for years to come.

Make Your Dock Safe for Young Family Members

In our last blog, we talked about accessories that can help make your dock safer. Here are a few
additional safety tips to go with them:

1. Choose Non-Slip Decking for Foot Traffic

Children tend to sprint across a dock toward the water — and slippery surfaces can turn that excitement into a dangerous slip. Non-slip decking materials are essential:

• Vinyl and Aluminum Decking with textured treads keeps traction even when wet and bare feet are involved. 
• Hand-sorted Lumber deck boards reduce the risk of splinters. 

Whether you select premium wood, vinyl, or aluminum options, surfaces designed to shed water and provide traction help prevent falls.

2. Keep the Dock Well-Lit

Good lighting isn’t just for evening dock parties — it’s a safety essential. Dock lights help families spot changes in walking surfaces, avoid tripping hazards, and safely transit the dock at dusk or after dark. 

Solar LED lights or post cap lights are easy to install and low-maintenance.

3. Keep the Walkway Clear & Organized

A cluttered dock is a tripping hazard:

• Store ropes, life jackets, and water toys in designated bins.
• Mount paddleboard and kayak racks to keep walkways clear and free of clutter. 

Organized docking space makes it easier for kids to walk without unexpected obstacles.

4. Ensure Regular Maintenance

A safe dock isn’t a one-time project — it’s ongoing care. Regular checks help catch and fix:

• Loose boards
• Worn connections
• Mildew or algae buildup that can make surfaces slick 

Routine cleaning and seasonal maintenance keep your dock structurally sound and safe for kids.

5. Safety Gear Should Be Easy to Access

Even with the best dock design, accidents can happen:

• Keep child-sized life jackets near dock entrances so kids can easily grab them before stepping onto the dock. 
• Have first-aid kits nearby with supplies for minor cuts and scrapes. 

When safety gear is visible and accessible, family members are more likely to use it.

Upgrade Your Dock Hardware This Off-Season

Need to upgrade your dock, but not ready to invest in a brand-new setup?

This off-season, you can replace parts and rebuild your existing dock to make it nicer for the spring, without committing to the time and price of installing an entirely new dock!

Replace Old Hardware & Upgrade Parts

Bolts, brackets, and cleats wear down over time. Replacing rusted or loose hardware now can prevent dangerous failures next season. Consider upgrading to higher-quality hot-dipped galvanized or stainless-steel parts for a longer-lasting dock.

If you already use our hardware, the hot-dipped galvanized won’t corrode, but it can still wear down with age. If your hardware is old, we recommend at least inspecting it to make sure it’s in good shape for next year.

Rebuild Your Old Dock

If your dock has seen better days but still has a usable frame, rebuilding may be the best option. New decking materials can bring fresh life to an old dock while keeping costs manageable.

Winterization vs Removal

What’s the difference between winterizing a dock and removing it from the lake?

In short, winterization is for boat docks that are permanent and can withstand winter weather in the lake, and removal is for docks that aren’t permanent. Here’s a few tips for preparing for both situations.

If You’re Leaving the Dock in for Winter

Whether or not a dock can be left in depends mostly on the lake.  If your lake doesn’t get large ice flows, AND there are no regulations against it, a dock can be left in. Ice flows are what usually cause dock damage, rather than just plain freezing.

If you’re leaving your dock in, you “winterize” the dock. If that’s your plan:

• Remove accessories like lights, ladders, bumpers, and cleats to protect them from ice damage.
• Double-check that cables, anchors, and hardware are in good condition to prevent shifting or breakage.

If You’re Removing the Dock

If your lake gets large ice flows or there are regulations against leaving it in, the dock needs to come out for the winter. If that’s the case:

• Always remove leg sets from each section before storing.
• Number your leg sets so when you install your boat dock next spring, you’ll have minimal re-leveling to do—saving both time and effort.
• Store sections and parts in a secure place to protect.  If you decide to cover them to protect them from snow and ice, be sure there is air flow.  Don’t seal them in completely.

Time to Start Planning for Fall!

How do you know when to start winterizing or removing your dock?

Here are a few tips on general timing, as well as regional recommendations!

Signs It’s Time to Start Planning

While every lake and river has its own seasonal rhythm, here are a few signs you should start thinking about dock removal or winterization:

• Water Temperatures Are Dropping. Cold water makes late-season work more uncomfortable and potentially unsafe.
• Weather is Becoming Unpredictable. Fall storms can bring wind, waves, and ice sooner than expected.
• End of Boating Season. Once you’re done with boats and personal watercraft for the year, your dock’s off-season prep can begin.

Regional Timing Recommendations

Your ideal timing will depend on your location. Here are a few examples:

• Northern Climates: Ice formation can start as early as October or November, so removal or winterization should happen before freezing conditions set in.
• Milder Regions: You may have more flexibility, but don’t wait until heavy winds or snow are in the forecast.
• Fluctuating Water Levels: If your area sees significant water level changes in the fall, factor that into your schedule to avoid working in unsafe conditions.

Prepping Your Dock for Summer Storms, Part 2

Is your dock ready for the best storm Michigan can throw at it?

In our last blog, we described two tips for protecting your dock from summer storms. Here are two MORE tips for keeping your dock in tip-top shape, even in Michigan’s wild summer storms!

Elevate Dock Height and Monitor Water Levels

• Pre storm adjustment: Ensure your dock is high enough that typical late summer waves won’t wash over the deck.
• Easy aluminum adjustment: Thanks to Alumi-Span’s lightweight anodized aluminum structure, leg-height modifications are quick and pain-free.

Protect Dock Electronics & Boat Equipment

• Power down and unplug: Disconnect lights, pumps, sensors—anything that uses electricity or floats water—before the storm hits.
• Bin and stow cords: Coil extension cables neatly and move them far enough inland to avoid flooding.
• Check boat covers: Secure all boat covers as recommend by manufacturer.  High winds can make covers into sails and can send boats flying, causing damage to not only the boat but docks as well.

Here are two tips for protecting your dock from storms and keep your investment in prime condition!

Secure and Stow Loose Items

• Quick sweep: Remove movable items such as chairs, hoses, planters, and equipment and store them inland.
• Tie down essentials: If something must stay dockside—such as dock lights or ladders—secure them with durable straps or bungee cords.

Reinforce Anchoring & Post Stability

• Tighten connections: Walk the perimeter, check all bolts in stringer brackets, and tighten any that are loose.
• Leg and brace check: On auger-anchored docks, give each leg a firm shake to ensure it remains firmly embedded—reset and tighten if needed.
• Boat secured correctly: If not on a lift, ensure the boat is tied correctly to allow for storm waves.  Check all ropes for wear.
