varillas

Varillas is the plural form of varilla, a term used in Spanish to denote a slender, cylindrical piece of material, typically metal or wood, that serves as a rod, stick, or small bar. The concept covers a range of practical items used as structural elements, fasteners, guides, or supports in different trades and applications. The word emphasizes length and slimness rather than a specific material.

In construction and civil engineering, varillas are commonly steel rods used for reinforcement. Varillas de acero, especially when ribbed or deformed, are embedded in concrete to improve its tensile strength and durability. They come in various diameters and lengths and are arranged into a reinforcing system known as rebar or armadura. Varilla de refuerzo is chosen based on the structural requirements, load conditions, and local building codes.

In mechanical and industrial contexts, the term also covers rods used as fasteners, alignment elements, or supports. Varillas roscadas, or threaded rods, are used to connect parts, create adjustable supports, or distribute loads in assemblies. Other uses include dowel-like or guide rods in machines, tooling, and fixtures, where the straight, smooth or finished surface can be important for fit and motion.

Overall, varillas denote slender, elongated pieces that function as fundamental building blocks in construction, machinery, and related crafts, with material, finish, and dimensions tailored to specific technical needs.
