Steel "s" Beams (standard)
Steel "S" Beams, or American Standard Beams, are hot-rolled structural beams designed with tapered flanges to optimize load distribution and strength. They are frequently used in heavy-duty structural frameworks.
Standard Steel Beams are engineered for load-bearing applications that require superior strength and rigidity. Their structural design makes them essential in large-scale commercial, residential, and industrial construction.
Steel "S" Beams are widely used in the construction of bridges, platforms, and building frameworks due to their high strength and support capabilities. Their shape provides efficient weight distribution over long spans.
