Stainless steel has less strength than standard roller chains and are suitable for light duty applications that require all stainless steel equipment such as food processing plants. ,
Coated has a surface treatment that withstands harsh outdoor environments such as exposure to seawater. They are stronger than stainless steel and offer more corrosion-resistance than nickel-plated chains. ,
Nickel-plated steel withstands mildly corrosive environments. They are stronger than stainless steel chains and are suitable in humid locations or for operations that require washdown. ,
Poly-steel has polyacetal links that reduce the weight of the chain while still providing resistance to temperature extremes and corrosion. They are suitable for light duty applications that do not require lubrication.
