Metal profiles and steel structural components used in the construction sector are constantly exposed to harsh outdoor conditions. Sun, rain, frost, salt air, and mechanical impacts — all of these factors directly affect the surface coating. That is why choosing the right coating for construction profiles directly determines the lifespan and safety of a structure.
Applications in the Construction Sector
- Steel door and window frames
- Balcony and staircase railings
- Steel scaffolding and platform systems
- Load-bearing steel columns and beams
- External facade metal panels and curtain walls
- Anchor and connection elements
- Steel roof elements and supports
Why Powder Coating, Not Liquid Paint?
- UV resistance: Quality powder coatings retain their color even after years of direct sunlight exposure
- Corrosion resistance: When combined with phosphating, powder coating provides superior protection in salty and humid environments
- Impact resistance: Withstands the inevitable knocks and abrasions of construction site conditions
- Speed: Parts are ready to use immediately after curing — no waiting time
Key Considerations for Outdoor Applications
- Choose polyester-based powder coating: Epoxy-based coatings are less UV-resistant outdoors; polyester is the recommended choice for exterior applications
- Film thickness should be 60–80 microns: Thin coatings provide inadequate protection in outdoor conditions
- Surface preparation must be thorough: The rust removal and phosphating stages must not be skipped
Choosing the Right Color
Color selection in construction projects is usually dictated by the architectural design. The RAL color standard ensures that the color code specified by the architect or property owner is communicated perfectly between manufacturer and applicator. The most frequently selected colors include RAL 7016 (Anthracite Grey), RAL 9005 (Jet Black), and RAL 8019 (Grey Brown).
