Quick Answer: How Much Does OSB 4×8 Sheet Cost?
The price of a 4×8 OSB sheet depends on market conditions and specifications.
Typical price ranges:
| OSB Thickness | Size | Approximate Price Range |
|---|---|---|
| 1/2 inch OSB | 4×8 sheet | USD $10–$25/sheet |
| 3/4 inch OSB | 4×8 sheet | USD $18–$40/sheet |
Prices may vary based on:
Country
Supplier
Quantity
Certification
Shipping cost
For bulk international orders, factory pricing from a reliable China OSB Board Supplier can be significantly different from retail market prices.
