Design
Architectural Metalwork require a mix of performance attributes, including aesthetics, UV, weather, and corrosion resistance, and much more.
At GreenMet AM, we combine expertise in architecture, civil engineering, design engineering, and industrial design to offer bespoke aluminium and steel fencing solutions. With a commitment to excellence and customer satisfaction, we take pride in delivering exceptional products designed to elevate your security and aesthetics.
Standards we follow
BS EN 1090 - Structural Steel and Aluminium Construction
Fences and barriers must be manufactured according to certified processes, including welding and structural assembly.
BS 1722 - Fences
Part 14 covers open mesh steel panel fences, often similar to aluminium barriers in function and appearance.
Part 9 specifies the requirements for steel palisade fencing, which includes similar materials such as aluminium in some contexts. It covers aspects like the height, width, and durability of fencing.
BS EN 1991 - Eurocode 1: Actions on Structures
Aluminium fencing should be designed to withstand expected wind loads, which are particularly relevant in large or open spaces.
BS 6180 - Barriers in and about Buildings
Aluminium barriers, particularly in public spaces or around buildings, must be designed to prevent falls and withstand loads from people or objects.
BS EN 755-2 - Aluminium and Aluminium Alloys
Ensures the correct grades of aluminium are used for the structural and durability requirements of fencing.
Building Regulations (Part K)
Aluminium barriers must be of adequate height and strength to prevent falling in specific contexts (e.g., balconies, stairs).
Protecting our products against corrosion
By adhering to C5 standards, aluminium products are suited for challenging environments, ensuring longevity and reduced maintenance costs.
PPC Coating Process for Class C5
Surface Preparation:
- Aluminium surfaces are cleaned and pre-treated, often with chromate-free treatments or anodising to ensure strong adhesion and corrosion resistance.
- Blasting may be used to roughen the surface, improving the powder’s grip.
Application of Powder Coating:
- A polyester or epoxy powder coating is electrostatically applied to the aluminium surface. The powder is chosen based on its performance under harsh conditions (UV, salt, and chemicals).
- Thickness of the coating is crucial; for Class C5, it typically exceeds 60 microns.
Curing:
- The powder-coated aluminium is cured in an oven at a high temperature (typically around 180-200°C), ensuring that the coating bonds tightly to the metal.
