Wood Framing is primarily from which species?

• A. Oak, Maple
• B. Fir, Pine or Spruce
• C. Cedar
• D. Bamboo

Answer: (B)

Wood framing relies on softwoods because they balance strength, workability, and cost. Fir, pine, and spruce grow in large quantities, provide long straight boards, nail and fasten easily, and offer a favorable strength-to-weight ratio for studs, joists, and rafters. They’re also readily available in standard sizes and more affordable than many hardwoods, making them the practical default for framing in most regions. Hardwood species like oak or maple are denser and harder to work with, which raises cost and labor without providing a necessary advantage for typical load conditions. Cedar is valued for exterior durability and corrosion resistance but is usually reserved for cladding, siding, or trim rather than primary structural members, while bamboo isn’t standard framing lumber in common building practices.
