Steel grating load capacity and span specifications
Steel grating load capacity and span specifications Steel grating load capacity and span specifications determine whether a walkway, platform, or trench cover will hold up under real-world conditions. Get the span wrong, and the grating deflects — or worse, fails. Get the load rating wrong, and you overpay for steel you do not need. This tutorial walks you through the engineering logic behind load tables, span limits, and bar spacing so you can specify grating with confidence. Introduction Every steel grating project starts with the same question: What load must this panel carry, and how far apart can the supports be? The answer is not a single number — it depends on bearing bar size, spacing, steel grade, and the type of load (uniform or concentrated). Many buyers rely on guesswork or copy a previous spec without checking whether the conditions match. That approach leads to either unsafe installations or wasted material. This guide covers the core calculations and reference data ...
