Choosing The Right Thickness Of Aluminum Diamond Plate For Boat Floors

The thickness of an aluminum diamond plate for a boat floor depends on several factors, including the grade of aluminum, the expected weight it needs to support, the spacing of the cross-supports, and personal preference for weight and cost. The thickness options that are typically available are 1/8, 3/16, and 1/4.

Some boat owners prefer 1/8 thick aluminum diamond plate as it is a good balance between weight and durability. Thicker plates will add more weight to the boat, while thinner plates may not be strong enough and may bend or sag over time, especially if the spacing between cross-supports is wider than 14 or 18.

It is also important to consider the finish of the diamond plate, as the bright finish can be slippery when wet, creating a safety hazard. Some boat owners choose to paint the diamond plate or treat it with a bed liner or non-slip coating to improve traction and reduce the risk of slipping. Sandblasting is another option to create a matte finish, but it can warp the metal and make it more difficult to clean.

Additionally, when installing an aluminum diamond plate floor, it is crucial to use aluminum or stainless steel for the framework to avoid mixing dissimilar metals, which can lead to corrosion. Proper sealing and fastening of the diamond plate are also essential to ensure a secure and long-lasting installation.

Thickness recommendations for aluminium diamond plate for boat floors

When choosing the thickness of aluminium diamond plate for a boat floor, there are several factors to consider, including the weight of the plate, the spacing of the cross supports, and the intended use of the boat. Thicknesses typically range from 1/8" to 1/4", with 1/8" being a common choice for those seeking a balance between weight and durability.

Weight Considerations

The weight of the aluminium diamond plate is an important factor to consider, especially if you are looking to keep the overall weight of the boat as light as possible. Thinner plates, such as those with a thickness of 1/8", will be lighter than thicker plates, such as those with a thickness of 1/4". However, it is important to note that thinner plates may not provide the same level of durability and strength as thicker plates.

Cross Support Spacing

The spacing of the cross supports underneath the boat floor is another crucial factor to consider when choosing the thickness of the aluminium diamond plate. If the spacing between cross supports is wider, you may need to opt for a thicker plate to ensure that the floor does not sag or flex. In general, a thicker plate will provide more support and rigidity, especially when combined with a good framework underneath.

Boat Usage

The intended use of the boat also plays a role in determining the appropriate thickness of the aluminium diamond plate floor. If the boat is primarily used for fishing or other activities that require standing for extended periods, a thicker plate may be preferable to provide added support and stability. On the other hand, if the boat is used for lounging or family outings, a thinner plate may suffice.

Finish and Traction

In addition to thickness, the finish and traction of the aluminium diamond plate are important considerations. Bright or mirror finish plates can be slippery when wet, especially if they have a polished finish. To improve traction, some people choose to sandblast the surface, apply a bed liner, or paint the floor with a light-coloured or textured paint. Alternatively, you can use rubber mats or marine carpet over the diamond plate to provide a non-slip surface.

Cost

Cost is also a factor to keep in mind when choosing the thickness of aluminium diamond plate. Thicker plates will generally be more expensive than thinner ones, and the price can vary depending on the alloy type and the supplier. It is important to weigh the benefits of a thicker plate against the additional cost to determine the best option for your specific needs.

Aluminium diamond plate flooring installation

Aluminium diamond plate flooring is a common choice for boats, thanks to its durability, ease of cleaning, and non-slip properties. It's also relatively easy to install yourself, although it's important to take the necessary precautions to ensure a safe and secure fit. Here's a step-by-step guide to installing aluminium diamond plate flooring in your boat:

Step 1: Choose the Right Thickness and Grade

Aluminium diamond plate comes in various thicknesses, typically ranging from 1/8" (0.125") to 1/4" (0.250"). The thicker the plate, the stronger it will be, but it will also add more weight to your boat. Choose a thickness that balances strength and weight, considering the expected load and the spacing of your boat's cross supports. Additionally, select the appropriate grade for your application. If you're only screwing or riveting the floor, 3003 tread-brite grade aluminium is suitable. However, if welding or forming is involved, opt for the more expensive 5052 grade.

Step 2: Prepare the Surface

Ensure that the surface you'll be adhering the diamond plate to is completely clean and dry. If the surface is glossy or smooth, rough it up with sandpaper to create a better adhesion. Remember to clean the surface thoroughly after sanding to remove any dust.

Step 3: Measure and Cut the Diamond Plate

Accurately measure the area where you want to install the diamond plate flooring. Transfer these measurements to the diamond plate, marking the cutting lines on the back, as the front side has raised bumps. Use a band saw, table saw, or circular saw to cut the plate to the required shape and size. For intricate shapes, a band saw is usually the best option.

Step 4: Smoothen the Cut Edges

After cutting, sand any sharp edges and burs to prevent injury and create a more aesthetically pleasing finish. You can use tools like tin snips or electric metal shears for this step, but remember to wear gloves to protect your hands.

Step 5: Drill Holes

Drill even holes along the tread plate edge, approximately 1/2" from the edge and spaced about 10" apart. You can adjust the spacing based on the size and shape of your floor plate. Use a 1/4" diameter drill bit for the holes.

Step 6: Secure the Diamond Plate

Now, it's time to attach the diamond plate to your boat's floor. If you're covering a metal surface, place the diamond plate over it and mark the holes on the existing surface. Drill corresponding holes in the surface for easy installation. Secure the diamond plate using self-tapping metal screws—1/8" screws for 1/4" holes.

If you're covering a wooden surface, you don't need to pre-drill holes in the wood. Simply use 1/8" wood screws to fasten the diamond plate securely.

Step 7: Apply a Non-Slip Coating (Optional)

If you anticipate using your boat in wet conditions, consider applying a highly abrasive non-slip surface coating to your diamond plate flooring. This will enhance traction and safety, especially when the floor is wet.

Additional Tips:

• When ordering diamond plate sheets, it's recommended to order 10% more material than you need to account for any mistakes or unexpected requirements.
• Always wear protective gear, including gloves, when working with diamond plate sheets and cutting tools.
• If you're unsure about the thickness, grade, or installation process, consult with experts or specialised contractors who can provide guidance and quotes.
