Why choose galvanised steel?
Galvanised steel is a popular choice for planters, raised beds, and outdoor furniture because it combines a timeless appearance with exceptional durability and minimal maintenance requirements. The protective zinc coating makes the steel highly resistant to rain, frost, and moisture, making it ideal for year-round outdoor use.
Designed for year-round outdoor use
At byJEMA, we create products designed to withstand outdoor use throughout the year. That is why we carefully select materials and finishes that can endure changing weather conditions while maintaining their appearance and quality for many years to come.
Our planters, raised beds, and outdoor furniture are manufactured from hot-dip galvanised steel, combining outstanding durability with a clean, timeless design.
Galvanised steel – what you should know
Galvanised steel products can be placed on most surfaces, including paving, concrete, gravel, and grass. For optimal durability and stability, we recommend installing the product on a level and well-supported surface.
A solid foundation helps ensure that the product remains stable and maintains its appearance over time. For larger planters or structures, we recommend installing the product on a compacted gravel or concrete base.
Always ensure good drainage in planters and raised beds. Standing water should be avoided, as it can negatively affect soil conditions and plant health.
Galvanised steel does not normally cause staining or discolouration of surrounding surfaces. However, on particularly delicate surfaces, regular cleaning is recommended to prevent the build-up of dirt, mineral deposits, or limescale.
Galvanised steel has a distinctive silver-grey surface that will gradually become more matte and uniform over time. This is a natural process and does not affect the material's durability or corrosion resistance.
Galvanised steel develops naturally
Galvanised steel is protected by a layer of zinc that provides long-lasting durability and excellent resistance to weathering.
When galvanised steel is new, the surface appears bright and slightly reflective, with the characteristic zinc pattern that is typical of the material.
Over time, the zinc surface naturally reacts with its surroundings and develops a more matte and uniform appearance. This is a completely natural process and does not affect the material's durability or corrosion resistance. Under normal outdoor conditions, galvanised steel will retain its protective properties for many years.
In periods of high humidity or prolonged exposure to moisture, light or whitish surface marks may occasionally develop. This typically occurs in areas with limited air circulation or where moisture remains on the surface for extended periods.
How to minimise the risk
✅ Ensure that the product is not covered by leaves or other materials that trap moisture.
✅ Avoid allowing the product to stand in stagnant water for extended periods.
✅ Ensure good drainage in planters and raised beds.
With normal use and proper drainage, galvanised steel will maintain both its protective properties and its distinctive appearance for many years to come.
No legal restrictions
Personal considerations when growing vegetables in galvanised steel
When using galvanised steel in the garden, including for growing vegetables and herbs, it is worth noting that there are no general legal restrictions on the use of galvanised steel for this purpose.
Galvanised steel is widely used in both private gardens and professional landscaping projects due to its long lifespan and excellent resistance to corrosion.
The decision to grow edible crops in galvanised steel planters is therefore largely a matter of personal preference and individual choices regarding garden design and aesthetics.
If you would like additional peace of mind, you can choose to line the inside of the planter with a geotextile fabric or a similar barrier between the soil and the steel.
This is not a requirement, but it is an option that some gardeners prefer for added reassurance.
Good drainage and nutrient-rich soil remain among the most important factors for healthy plants and successful growing conditions—regardless of the material used to construct the planter.
Ultimately, the choice is yours. Galvanised steel combines a clean, timeless appearance with exceptional durability and minimal maintenance requirements.
For many gardeners and landscape designers, the choice of material comes down to aesthetics, growing needs, and personal preferences.
Galvanised steel – built to last
Galvanised steel is designed to withstand the Nordic climate and requires only minimal maintenance. Although laser cutting breaks the zinc coating along the cut edge, the majority of the galvanised protection remains intact.
Any scratches or processed edges will continue to benefit from the protective effect of the surrounding zinc coating, contributing to the material’s long service life.
Simple cleaning with lukewarm soapy water and a soft cloth or sponge is typically all that is required to maintain the product’s appearance and performance.
From bright to a natural patina
When galvanised steel is new, the surface appears bright and reflective, with the characteristic zinc pattern typical of the material.
Over time, the zinc coating naturally reacts with its surroundings and develops a more matte and uniform appearance.
This process is completely natural and does not affect the material’s durability or corrosion resistance.
A timeless choice for modern gardens
Galvanised steel is a popular choice for planters, raised beds, and outdoor furniture alike. Its bright, elegant surface creates a striking contrast to the greenery of the garden and blends naturally into both modern and traditional outdoor spaces.
The material combines a clean, contemporary design with practical benefits and requires only minimal maintenance. For this reason, many homeowners choose galvanised steel when creating outdoor spaces with solutions that are both visually appealing and built to last for many years.
