Will my stainless steel planter rust?

The two grades commonly used for outdoor planters are 316 grade, known as marine grade, and 304 grade, more commonly used for outdoor planters. Both grades are suitable for use at inland locations whereas 316 grade is recommended for use in coastal, marine or heavily chlorinated environments. Our standard planters come in 304 grade stainless steel with a fine brushed finish.

To periodically clean the planters use non-abrasive cloth and warm water with or without a gentle detergent. Always wipe with the directional grain of the steel. After washing, rinse with fresh water and dry thoroughly.

Salt water air and other chemical may result in small brown spots appearing on the surface of the planter. The spots can be easily removed by gently rubbing the surface of the steel, in the direction of the brushed finish, with a Scotch-Brite pad.

Stainless steel will not rust but it is vulnerable to salt air and chlorine. 316-grade stainless steel is made with molybdenum and is manufactured for costal use. The molybdenum provides higher resistance to pitting and crevice corrosion and gives 316 better overall corrosion resistant properties.

A stainless steel planter will provide you with years of use and enjoyment without rust.
