Strong piece of eg wood or metal used in construction (4)

I believe the answer is:

beam

(Other definitions for beam that I've seen before include "Ray; piece of timber" , "Ray of light or a large smile" , "Light - heavy timber - wide smile" , "Shine" , "Ray of light - structural piece of wood" .)

I've seen this clue in The Guardian.
