Zinc Planter Quality Comparison

Zinc Planter Quality Comparison

Zinc planters are a popular choice for many gardeners. Often admired for their contemporary modern look and durable qualities, it’s no wonder zinc planters are growing in popularity. Find out what makes our zinc planters better than the rest in our Zinc Planter Quality Comparison guide.

What Makes our Zinc Planters Better than the Rest?

Our range of planters have been made from steel and coated in a layer of zinc; a tough and durable duo. Steel, though known for its strength, is also prone to rust, but don’t worry! We’ve coated our planters in a layer of hardy zinc to protect it from rust and make it last.

Our planters have a steel thickness of 0.69mm on planters up to 60cm, and a thickness of 0.80mm on planters exceeding this size. To protect the steel, they have been electroplated in zinc at a thickness of 120g/m2.

Often you will find other manufacturers galvanising their planters at a much lower quality of around 40g/m2. This thinner coating has far less protection and is much less durable. We want your planter to last as long as possible, and with our thick zinc coating, your planter will do just that.

Caring for Your Zinc Planter

Zinc provides the raincoat that your steel planter needs, helping to protect it from water and subsequent rusting. Our planters are tough and durable, but there are still ways in which a galvanised planter can be affected.

1. Scratches and other mechanical damage
It’s crucial to be careful not to scratch its surface, as once the steel is exposed, rusting can occur.

2. Impurities in the soil and air
Zinc won’t be degraded by oxygen and pure water but there are many trace chemicals, especially in soil and fertiliser. These chemicals will slowly react with the zinc until one day the steel is exposed, and rusting will start to set in.

Although you can place soil directly into these planters, we advise using a thick, non-biodegradable plastic liner or bag to help protect your planter from these trace chemicals. This simple trick will help to prolong the life of your planter, so that you can enjoy it for longer. Learn how to line a planter in our useful guide.
