Frequently Asked Questions about Planterscape Products:

What is Corten Steel?

Corten steel is a weathering steel which develops a self protecting rust patina when exposed to the weather elements.   The rust patina resists corrosion, requires no treatment or weather-proofing, and does not compromise structural strength of the steel.  Unlike raw steel, Corten steel is corrosion resistant due to its alloy composition - it will not show bubbling, flaking or peeling, which normally occurs with raw steel.  Rather, a soft intended layer of rust blankets the steel with deep earthy tones and is why Corten is favored among architects and artists.  Corten steel is made from recycled content and is 100% recyclable.

Inherent in the natural rusting process of Corten Steel, variations in color, hue, and texture should be expected.  Also, the handcrafted fabrication of our products may result in slight variations. These are not considered flaws or defects.

How do I care for my planter?

Corten steel will produce a carbon run-off which will stain stone, concrete, and decking surfaces if not allowed to weather first. To limit staining to surrounding surfaces, place your planter in grass or soil during the initial weathering period. The weathering rate ranges from 3-9 months depending on location.  Planterscape steel planters do not come pre-weathered.

Should I insulate my planter?

While your Planterscape planter will hold up to the elements of a hard winter, your perennials may not despite the USDA hardiness zone.  The USDA hardiness zone indicated for your area does not mean your perennials can necessarily survive a winter above ground.  To survive a winter in a container, your plants should be rated hardy 2 zones lower than your area's hardiness zone. However, it is also recommended that you insulate your planter.

How do I insulate my planter?

Prior to planting the planter with soil, line the inside of your planter with 0.5"- 1.0" of bubble wrap or 0.5"- 1.0" foam insulation.   This prevents the roots from coming in contact with the metal, which could be susceptible to extreme temperatures.  Bubble wrap can be recycled from any packaging you receive from purchases or can be purchased at any office supply store.  Foam insulation can be purchased at large home improvement stores and is available in various sizes, including convenient project panels (1"x 24"x 24"). The insulation can be cut into panels and sized to fit the interior dimensions of the planter.

WARNING: Must Read Before Use.

Fire pits are extremely hot when in use. This product is designed to allow clearance around the stove unit for proper ventilation and decrease of heat transfer to table surround; however, exercise the same caution you would with any open fire and heat surface, using protective gear if necessary. Discoloration of finish may occur beneath a fire pit due to extreme heat, but may be minimized by use of a manufacturer's stand.  Follow all operating instructions and user warnings designated by fire pit manufacturer.
