Which type of beam is typically preferred for long spans where depth is a concern and point loads are significant, such as supporting heavy roof loads over a large open space?

Question: Which type of beam is typically preferred for long spans where depth is a concern and point loads are significant, such as supporting heavy roof loads over a large open space?

Answer options: ✅ Glued-laminated timber (Glulam)

• Solid sawn lumber beam
• Wood I-joist
• Light-gauge steel C-channel

Correct answer: Glued-laminated timber (Glulam)

Explanation: Glued-laminated timber (Glulam) beams are manufactured by bonding together multiple layers of dimensional lumber. This process allows for creation of very strong, stiff beams capable of spanning long distances and handling heavy loads, making them ideal for large open spaces.
