If you are asking how much does diamond plate aluminum cost, you are likely planning a construction, trailer, or industrial project. The price of aluminum diamond plate depends on size, thickness, alloy, and supplier.

Average cost of diamond plate aluminum
The cost of diamond plate aluminum is usually calculated per sheet, per square foot, or per kilogram, depending on the supplier.
Typical price range (reference only)
| Size | Thickness | Price Range (USD) |
|---|---|---|
| 4×8 | 1.6 mm (0.063″) | $90 – $140 |
| 4×8 | 2.5 mm (0.100″) | $130 – $200 |
| 4×8 | 3.2 mm (0.125″) | $180 – $280 |
| Per sq ft | 2.0–3.0 mm | $6 – $14 |
Prices vary by region and market conditions.
Cost by thickness
Thickness is one of the biggest factors affecting diamond plate aluminum cost.
| Thickness | Common Use | Relative Cost |
|---|---|---|
| 1.6 mm | Decorative panels | Low |
| 2.0 mm | General flooring | Medium |
| 2.5 mm | Trailers, truck beds | Medium–High |
| 3.2 mm | Heavy-duty platforms | High |
Thicker sheets cost more due to higher aluminum content.
Cost by aluminum alloy
Different alloys have different strength and corrosion resistance.
| Alloy | Grade | Price Level | Notes |
|---|---|---|---|
| 3003 | H22 / H24 | Lower | Most common, good formability |
| 5052 | H32 | Higher | Stronger, marine-grade |
If you need higher strength or outdoor durability, expect a higher price.
How much does a 4×8 sheet of diamond plate aluminum weigh?
Weight affects shipping cost and total price.
| Thickness | Approx. Weight |
|---|---|
| 1.6 mm | ~48 lbs (22 kg) |
| 2.5 mm | ~75 lbs (34 kg) |
| 3.2 mm | ~95 lbs (43 kg) |
Heavier sheets increase transportation costs.
What factors affect diamond plate aluminum cost?
Several factors influence the final price:
- Aluminum market price
- Sheet size and thickness
- Alloy type
- Quantity ordered
- Supplier location
- Shipping and handling
Buying in bulk usually lowers the cost per square foot.
Local suppliers vs factory pricing
| Source | Price Level | Best For |
|---|---|---|
| Local metal supplier | Higher | Small orders, fast pickup |
| Online distributor | Medium | Nationwide delivery |
| Aluminum factory | Lower | Wholesale and custom sizes |
If you need large volumes, factory-direct sourcing often offers better value.
Is diamond plate aluminum more expensive than flat aluminum?
Yes, diamond plate aluminum typically costs more than flat aluminum sheets because:
