Lintels are typically made from which materials?

• A. Stone
• B. Wood
• C. Steel or precast concrete
• D. Plastic

Answer: (C)

Lintels are the load-bearing members placed above openings that transfer the weight of the masonry or structure above to the sides of the opening. In modern construction they’re typically made from steel or precast concrete because these materials provide the necessary strength, predictable performance, and fire resistance for supporting openings of various widths. They also offer durability and easier installation for architectural and structural requirements. Stone lintels exist, but they’re heavy and less versatile for different spans, and wood is prone to rot and insect damage, while plastic generally cannot provide the required strength or fire performance.
