Introduction
Corten steel planters are unique in the sense of the ability to combine both aesthetic charm and practical functionality. These planters are often known for their distinctive weathered appearance and remarkable durability. Keep reading to explore the science behind Corten steel, the sustainability benefits of these planters, innovative uses, and the customisation options available so that they are manufactured to the end users' unique needs. Our goal is to provide you with valuable information so you can make the most of these outdoor space elements.
The Science Behind Corten Steel’s Weathering Process
Corten steel, frequently known as weathering steel, is an alloy which develops a rust-like patina over a short period of time. This patina is more than just for appearance; it is very stable and serves as a protective layer which prevents the planter from further corrosion. Briefly, here is an overview of the process:
- Oxidation: Initially, the steel reacts with oxygen and moisture forming a layer of iron oxide (rust).
- Stabilisation: Unlike regular steel, where rust continues to eat away at the metal, Corten steel stabilises after forming a thin layer on the surface. This is thanks to alloying elements such as copper, chromium, and nickel, which promote the formation of a dense, adherent oxide layer that prevents further oxidation. Learn more about weathering steel.
Corten steel’s rusting process begins within days and can take up to 9 months to fully develop. Everforms planters are usually delivered in a raw steel/metallic finish, however, we can deliver at various stages of the weathering process, from new steel to full patina.
When looking for a durable choice for outdoor use, corten steel is the ideal choice as it offers natural protection, reducing the need for maintenance and ensuring longevity even in harsh weather conditions that we come by in the UK!
Innovative Uses and Placement Ideas
Corten steel planters are most commonly found in modern gardens, however, their applications go far beyond conventional placements. Here are some of our ideas on how else you can incorporate these into your space:
- Vertical Gardens: Only have a small area to utilise? Take advantage of tall, narrow planters to create vertical gardens, adding greenery to small spaces or walls. The contrast between the foliage and the weathered steel creates a striking visual effect.
- Outdoor Dividers: Does your space need to be more clearly defined? You can use large, rectangular planters to serve as a stylish divider between areas of your outdoor space. Using planters to separate patios, seating areas or pathways can offer privacy and can be planted with tall grass or bushes for added seclusion.
- Water Features: Want your planter to stand out? Think about choosing a planter without drainage holes and adding a waterproof lining so you can transform your planter into a unique feature. The combination of water alongside the warm hues of Corten steel creates a tranquil area that will enhance any garden.
- Edging and Border: Recently fitted a pathway? Smaller planters can be used as edging elements alongside pathways or garden beds. Their natural, earthy tones blend seamlessly with stone, gravel and wood, providing a cohesive look.
