Material Performance Comparison
| Type | Description | Tensile Strength | Yield |
|---|---|---|---|
| 304 | Excellent corrosion resistance, high tensile strength. Ideal for chemical processing, food industries, power plants, and wastewater treatment. Suitable for high-temperature applications. | 75,000 psi (min.) | 30,000 psi (min.) |
| 316 | Superior corrosion and pitting resistance compared to 304. Excellent heat resistance for chemical, pulp, paper processing, marine environments, textile equipment, and petroleum refining. | 75,000 psi (min.) | 30,000 psi (min.) |
Load & Deflection Standards
| Metric Legend | Imperial Legend |
|---|---|
| U = Safe Uniform Load (kPa) C = Safe Concentrated Load (kN/meter of grating width) D = Deflection (mm) |
U = Safe Uniform Load (lbs./ft²) C = Safe Concentrated Load (lbs./foot of grating width) D = Deflection (inches) |
