Different metal surfaces compared
Metal is not just metal – this is especially true when choosing the right surface for your DIY project. Whether indoors or outdoors, whether furniture making, garden design or privacy screens: the surface influences both the appearance and the durability and care properties of your workpiece.
In this blog article, we give you an overview of the most common metal surfaces and show which ones are particularly well suited to your projects.
1. Raw metal
Typical for: industrial look, indoor furniture making, decorative DIYs
Suitable for: aluminium, steel, stainless steel, brass
Raw metal surfaces are natural, uncoated and show the original structure of the material. Visible weld seams, grinding marks or signs of use are especially popular in the industrial style – they add character.
Tip: Use untreated metal only indoors or protect it with clear lacquer, oil or wax. Otherwise, corrosion may occur – especially with steel or iron.
2. Brushed
Typical for: modern furniture, kitchen cladding, privacy screens
Suitable for: stainless steel, aluminium
Brushed surfaces are created through a uniform sanding process. They have a matt sheen, are slightly textured and are particularly resistant to fingerprints – a major advantage in everyday use.
3. Powder-coated
Typical for: outdoor projects, garden furniture, railings, privacy screen elements
Suitable for: aluminium, steel, stainless steel
Powder coatings are not only extremely resistant to weathering, scratches and UV radiation – they also offer maximum design freedom: choose your preferred colour from over 1,500 RAL colours in our shop!
4. Anodized
Typical for: window frames, balcony components, design elements
Suitable for: aluminium only
During anodizing, the natural oxide layer of aluminium is strengthened through an electrochemical process. This provides excellent corrosion protection while also creating a decorative appearance!
5. Galvanized
Typical for: fences, posts, structural parts for outdoor use
Suitable for: steel
Galvanized metal parts are coated with a protective layer of zinc that prevents rust. A distinction is made between hot-dip galvanizing (thick, robust) and electrogalvanizing (thinner, visually finer).
Tip: Ideal for anyone looking for a low-maintenance outdoor solution.
6. Polished
Typical for: interior construction, furniture, decoration
Suitable for: stainless steel, brass, aluminium
Polished metals shine with a high gloss – they look elegant and reflect light particularly well. Outdoors, however, they are more sensitive to scratches and weathering.
Tip: Use polished surfaces more for accents than for large, heavily used areas.
Which metal surface suits which project?
- Indoor areas: raw, brushed or polished surfaces for furniture, decoration and design accents.
- Outdoor areas: powder-coated, anodized or galvanized surfaces for weather protection and durability.
- Garden and terrace: powder-coated metal for railings, privacy screens, planters and garden furniture.
- Modern architecture: brushed stainless steel or anodized aluminium for a clean, high-quality look.
- Industrial style: raw metal for deliberately visible material structure and characterful surfaces.
Our conclusion
The choice of surface should match your project goal, the place of use and your desired style. While raw or brushed metals tend to shine indoors, powder-coated, anodized or galvanized surfaces are ideal for outdoors. Polished variants create highlights – but are more sensitive.
With our configurator, you can define not only dimensions, material and profile shape – you can also order the right surface finish directly. This makes your project not only stable and precise, but also visually exactly to your taste.
Frequently asked questions about metal surfaces
Which metal surface is suitable for outdoors?
Powder-coated, anodized or galvanized surfaces are particularly suitable for outdoor use. They protect the metal better against weathering, moisture and corrosion.
What is the difference between brushed and polished?
Brushed surfaces have a matt sheen and are slightly textured. Polished surfaces are significantly glossier, reflect more strongly and look particularly elegant.
Which projects is powder coating suitable for?
Powder coating is particularly suitable for outdoor projects, garden furniture, railings, privacy screen elements, balcony cladding and metal parts that should be durable and individually designed in colour.
Can aluminium be anodized?
Yes. Anodizing is suitable exclusively for aluminium. The natural oxide layer is strengthened, making the surface more corrosion-resistant and visually higher quality.
