''A wooden construction made from [[log]]s, [[plank]]s and [[ribbon|metal ribbon]]s intended to support walls in [[mine]]s.''
Used to reinforced reinforce cave walls and floors in caves/[[mine]]s/tunnels.
== Usage ==
* A reinforced floor can be mined to remove beam reinforcement with 21 [[body strength]]. No shard is produced in this process, and the slope does not change.
* Finished support beams do not fit into a small cart, rowing boat, or small sailboat.
* Adding a reinforcement is considered [[paving]] for priests.
