The powder coating process
Together with affiliated and our own companies, we offer our customers a one-stop powder coating process at several locations. The use of powder coating using polyester resin (SP) is standard for external applications. This is particularly resistant to weathering (good UV resistance). The chalking and discolouration behaviour is significantly lower than that of epoxy resin powder (EP), which is primarily used for priming due to their high chemical and diffusion resistance.
The following layer structures are possible
- Powder-priming as an option for a better surface finish (optics)
- Powder epoxy primer as an option for chemical stability (corrosion protection)
- Powder-SP topcoat is our standard for hot-dip galvanized surfaces
- Clear-coat powder coating to add gloss to matt pearl effect colours, for example
- Anti-graffiti powder coating on request, for easier to clean
Colour groups
- Single coats according to RAL or special colours on request
- Metallic coatings according to RAL or DB colour or on request
- Iron mica coatings according to RAL, DB colour or on request
- Pearl mica coatings RAL with major colour deviations
(single layer only in matt, gloss is possible by adding another clear coating)
Surface finish
- Glossy is our standard in all RAL and DB colours
- Coarse texture only on special request
- Fine texture possible for all DB colours
(RAL 9006, RAL 9007 and other colours on request)
Square meter calculation of components
We have compiled the calculation methods for square meter calculation for you here.
Powder coating of sheet metal, perforated sheet metal & expanded metal
- L x W x 2 ( total area incl. angled surfaces)
Powder coating of railings and blacksmith products
- Flat iron: < 70 mm = L x H
- Flat iron: > 70 mm = L x H x 1.5
Powder coating of two-dimensional structures
- Industrial and decorative blacksmith products: L x H (unless the profile surface is larger)
Powder coating of edged sheets (smooth, punched), expanded metal
- (B1 + B2 + B3 + B4 + B5) x L x 2
Powder coating of poles
- Profile circumference x L x 1.25 (minimum circumference = 150 mm)
Powder coating of stairs
- Stairs with steps: L x W x 2
Powder coating of railings and fence elements
- Rail and fence elements (up to cross bars): < 70 x 8 mm distance of cross bars at least 100 L x H
- Rail and fence elements at the top: > 70 x 8 mm distance of cross bars at least 100 L x H x 1.50
Powder coating of hand rails
- Hand rail: Min. 150 mm x L
- Hand rail with bracket: Min. 200 mm x L
- Curved and tiered hand rail: Min. 150 mm x L x 2
Coating of three-dimensional structures
- L x H (x 2)
Coating of angled railings
- (L1 + L2 + L3) x H (x 2)
Coating of profiles
- Rolled profile = 1D construction steel: Circumference x L (min. circumference = 150 mm and circumference = paint surface steel profile table)
- Pipe profiles, square profiles and rolled profiles with base plate: Circumference x L (min. circumference = 150 mm and circumference = paint surface steel profile table) x 1.05
- Pipe profiles, square profiles and profiles with head and base plate: Circumference x L (minimum circumference = 150 mm) x 1.10
Coating of bevel parts
- (B1 + B2 + B3 + B4 + B5) x L x 2 (x 2)
