Vinkeljärn

Vinkeljärn, also known as angle iron or angle steel, is a type of metal bar that is L-shaped in cross-section. It is formed by bending a single sheet of metal at a 90-degree angle. Vinkeljärn is commonly manufactured from steel, but can also be made from aluminum, stainless steel, or other alloys. The two legs of the "L" can be of equal or unequal length, and their thickness can also vary.

This structural shape is widely used in construction and fabrication due to its versatility and strength. It serves as a fundamental building component for frames, supports, and bracing in various structures. Applications include the construction of buildings, bridges, machinery, and furniture. Its right-angled form makes it ideal for joining other materials at corners or creating right-angle connections.

Vinkeljärn can be found in different finishes, such as hot-rolled, cold-formed, or galvanized, depending on the intended use and environmental conditions. Hot-rolled vinkeljärn is typically used for general construction where precise dimensions are not critical, while cold-formed vinkeljärn offers tighter tolerances. Galvanization provides corrosion resistance, making it suitable for outdoor or moist environments. The material's strength-to-weight ratio and ease of cutting, drilling, and welding contribute to its widespread adoption in numerous industrial and DIY projects.
