Metalltrådgitter

Metalltrådgitter are metal latticed structures composed of interwoven or welded metal bars that form a grid or mesh. They are commonly used as structural support, shading devices, decorative railings, or protective barriers on buildings, bridges, and military or industrial installations. The grids can be made from various metal alloys, such as steel, aluminum, or stainless steel, each chosen for its mechanical properties or environmental resistance. Welded configurations offer rigidity and load‑bearing capacity, while bolted or riveted panels allow for easy disassembly or maintenance.

Typical applications include traffic circles, where the grill improves visibility while preventing vehicles from entering closed areas, or on bridge decks to provide a non‑slip surface. In architectural contexts they may serve as perforated walls, partition screens, or ornamental panels in atria and foyers. Industries often employ gitter structures for containment of hazardous materials or as barriers in secure facilities.

Manufacturing methods involve extrusion of bars followed by cutting and bending, or forging and roll‐forming wherein the grid shape is stamped from a flat plate. Finishes vary from galvanised or powder‑coated to anodised aluminium, offering corrosion protection and aesthetic options. Design standards such as Eurocode, EN 10204, and local building codes specify tensile strengths, fire resistance, and load capacities.

Historical use of metal grilles dates back to early railway platforms and industrial factories, evolving into modern safety features on public transportation hubs and office towers. Advances in metallurgy and automated welding processes have expanded the availability of lightweight, high‑strength alloys, enabling slimmer profiles and higher load capacities. Despite being simple in concept, metalltrådgitter serve a critical role in safety, accessibility, and architectural expression across a broad spectrum of built environments.
