It is not just one thing. It is five things working together.<\/span><\/p>\n<h3><b>Corrosion risk (chlorides, humidity, pollution)<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">This is the biggest enemy. <\/span><b>Chlorides<\/b><span style=\"font-weight: 400;\"> are salt. Salt is in the sea air. It is in pool water. It is used to melt ice on roads. Salt eats steel. This causes ugly brown marks called <\/span><b>tea staining stainless steel railing<\/b><span style=\"font-weight: 400;\"> or even small holes. This is <\/span><b>pitting corrosion chloride resistance railing<\/b><span style=\"font-weight: 400;\">. Another problem is <\/span><b>crevice corrosion in railing fittings<\/b><span style=\"font-weight: 400;\">. We measure this resistance with a <\/span><b>PREN rating stainless steel railings<\/b><span style=\"font-weight: 400;\">. A higher number is better.<\/span><\/p>\n<h3><b>Safety &amp; stiffness (wall thickness, spans, connection design)<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A railing must keep you safe. It cannot bend or break. The <\/span><b>structural steel for guardrails<\/b><span style=\"font-weight: 400;\"> must be strong. The <\/span><b>stainless steel railing tolerance and wall thickness<\/b><span style=\"font-weight: 400;\"> are very important. This is why standards like <\/span><b>IBC guardrail requirements stainless steel<\/b><span style=\"font-weight: 400;\"> \u0456 <\/span><b>OSHA railing compliance materials<\/b><span style=\"font-weight: 400;\"> exist.

A <\/span><b>brushed finish stainless steel railing<\/b><span style=\"font-weight: 400;\"> looks soft. A <\/span><b>mirror polished stainless steel balustrade<\/b><span style=\"font-weight: 400;\"> is shiny and bright.
