What is the minimum grade of lumber recommended for load-bearing walls?

• A. Utility grade
• B. No.3 grade
• C. No.2 grade
• D. Stud grade

Answer: (D)

The minimum grade of lumber recommended for load-bearing walls is referred to as stud grade. This designation indicates that the lumber is suitable for structural applications and can adequately support loads. Stud grade lumber is specifically engineered and graded to ensure it meets the necessary strength and stability requirements for framing walls. When it comes to building load-bearing walls, the materials used must be reliable and capable of handling the weight they will bear, including the load from the roof, upper floors, and any additional structural elements. Stud grade lumber has passed specific inspections and testing regulations, confirming its performance for these applications. In contrast, utility grade, No.3 grade, and No.2 grade lumber may not meet the necessary structural standards for load-bearing applications due to their potential for defects or reduced structural integrity. Therefore, stud grade lumber is the optimal choice for ensuring a safe and reliable construction that adheres to building codes and best practices.
