Why choose a raw marine grade stainless steel flat bar?
The raw marine grade stainless steel flat bar, made from 316L stainless steel, is the go-to choice for projects exposed to salt corrosion, chlorine, or intense humidity. Its molybdenum content provides enhanced protection compared to standard 304L stainless steel.
Exceptional resistance in marine environments
This 316L stainless steel flat bar is ideal for boat building, coastal railings, pool structures, boat reinforcements, or outdoor installations in coastal areas. The raw finish preserves the authentic metal look while ensuring exceptional longevity without deterioration.
Use & maintenance tips
Easy to drill, cut, and weld, this flat bar integrates perfectly into marine metalwork or technical construction projects. Despite its high resistance, occasional rinsing with clean water is enough to remove salt deposits and preserve its original appearance.
