For stainless steel material, the more corrosive, the lower carbon composition percentage; the more corrosive, the higher nickel composition.
The carbon composition/C is below 0.08, the nickle composition/Ni is 8 for stainless steel 304, the carbon composition/C is below 0.08, the nickle composition/Ni is 10 for stainless steel 316.
For costal and humid areas, it is more corrosive environments, stainless steel 316 is the most situable option.
The security screen is usually in pieces, it is with high impact strength, anti-theft, and good ventilation.
