In the A&D industry, this word has several meanings, but they all essentially mean the same thing, even if they appear to be completely different. All stringers have to do with stability in construction. Whether they are made of metal or wood, are purely functional or also decorative, stringers are integral to the safety of the “system” at hand.
In regard to stair assemblies, stringers are the sloped members that support the stairway. In ceiling systems, these long horizontal pieces tie in trusses and add strength to the construction; they support joists or other cross members. In raised floors they are the horizontal members that connect uprights in a frame and support the floor. In furniture – such as chairs, tables, and benches – they are the low pieces that connect the legs together, providing the piece strength and making it safe to use.
