Product Parameters

Features

Material Grades:     Common grades: 304, 304L, 316, 316L, 321, 2205 (Duplex).
    316/L is ideal for marine & chemical environments (high molybdenum   content).
    Duplex 2205 offers higher strength and chloride resistance.
   
    Advantages:     Corrosion Resistance: Excellent performance in humid, acidic, or saline   conditions.
    High Strength: Suitable for structural and load-bearing applications.
    Aesthetic Finish: Polished or brushed options for architectural use.
    Low Maintenance: Does not require protective coatings like carbon   steel.
   
   
    Standard Sizes & Specifications:     Available in standard (S), wide-flange (W), and lightweight (L)   profiles.
    Dimensions follow ASTM A554, EN 10088, or custom specifications.
    Typical sizes: 3" to 12" (flange width), varying web   thicknesses.
   
    Fabrication & Welding:     Can be cut, drilled, and welded (TIG/MIG recommended).
    Requires proper techniques to avoid weld decay (e.g., low-carbon 304L/316L   for welding).
