Teräspatterit

Teräspatterit, often translated as steel gratings or steel grids, are versatile structural components manufactured from steel. They consist of a series of parallel load-bearing bars, known as bearing bars, that are typically welded or mechanically interlocked to perpendicular connecting bars, or cross bars. This construction creates a strong, open mesh pattern that allows for the passage of light, air, and liquids while providing a stable and load-bearing surface.

The manufacturing process for teräspatterit usually involves resistance welding or pressure-locking, ensuring the integrity and strength of the interconnected bars. They are commonly made from mild steel, stainless steel, or aluminum, depending on the intended application and environmental conditions. Common finishing treatments include galvanization for corrosion resistance, particularly in outdoor or humid environments, or electro-polishing for aesthetic appeal and enhanced hygiene in food processing or pharmaceutical industries.

Teräspatterit find extensive use in a wide range of applications due to their durability, load-bearing capacity, and safety features. They are frequently employed as flooring in industrial settings, walkways, stair treads, platforms, and mezzanines. Their open structure makes them ideal for drainage purposes and for preventing the accumulation of debris. They are also utilized as protective coverings for ventilation openings, cable trays, and as structural elements in bridges and offshore platforms. The specific design, including the spacing and dimensions of the bars, can be customized to meet particular load requirements and safety standards.
