Cold work can induce slight magnetism. If low magnetic permeability is critical, specify it up front and test samples.<\/p>\n<p><strong>What finish should I choose for public railing?<\/strong><br \/>\nBrushed finishes hide fingerprints and minor scuffs. Mirror gives a premium look but shows handling more readily. Match the <strong>acabamento<\/strong>\u00a0to traffic level and cleaning plan.<\/p>\n<p><strong>Can I use 304 near the ocean?<\/strong><br \/>\nYes, but for piers and direct splash from the sea, 316 usually performs better in <strong>ambientes de \u00e1gua salgada<\/strong>. For inland <strong>marinha<\/strong>\u00a0climates with occasional salt exposure, 304 may suffice with proper design and cleaning.<\/p>\n<p><strong>How does square compare to round for structures?<\/strong><br \/>\nSquare makes flat-face connections easy and looks modern. Round is efficient for torsion and bending. Many projects use both: square for frames and round for ties and rails.<\/p>\n<p><strong>Does 304 handle mild acids or cleaners?<\/strong><br \/>\nIn many cases yes, but always test the exact <strong>qu\u00edmica<\/strong>\u00a0and concentration. Persistent <strong>\u00e1cido<\/strong>\u00a0splash or high-temperature chlorides demand special care or upgraded materials.<\/p>\n<p><strong>Can I get matching rectangular and square in one delivery?<\/strong><br \/>\nAbsolutely.
