Highest standards & tested safety
As a premium staircase manufacturer, we undergo ongoing quality controls in all relevant areas and implement reliable and uniform product and testing standards in planning and design, in the production and in the assembly and installation.
We are certified according to…
Welding Certificate EXC-2 for Steel and Stainless Steel
Welding Certificate EXC-3 for Steel and Stainless Steel
FPC Certificate EXC-3 Steel
AbP for All-Glass Railings System MetallArt (own licences with general test certificates issued by the building authorities)
Certifications for load-bearing steel components in accordance with the execution classes (EXC) stipulated by DIN EN 1090
As a certified specialist welding company, the CE marking for steel stairs, which has been legally required since 1st July 2014, is a matter of course for MetallArt. It includes the proof of work in accordance with DIN EN 1090 required for the development and manufacture of load-bearing steel components as well as the factory production control (FPC). The FPC system set up in our company is regularly tested and monitored by a monitoring and certification body recognised by the German Centre of Competence in Civil Engineering (DIBt). Depending on the type of construction, different execution or hazard classes apply. The “Execution class (EXC)” according to which the component is to be manufactured, must be determined by the office issuing the invitation to tender (architect, planner), depending on the desired resistance of the steel material, the welding process and other criteria. MetallArt holds the following qualifications:
- Certification | Welding certificate as per DIN EN 1090-2 (steel) EXC2:
Approval for predominantly and not predominantly statically loaded steel components or steel load-bearing structures up to strength class S 700, which are not classified in EXC1 or EXC3
- Certification | Welding certificate as per DIN EN 1090-2 (steel) EXC3:
Approval for predominantly and not predominantly statically loaded steel components or steel load-bearing structures up to strength class S 700, which are among the following structures:
- building with more than 15 storeys
- large-area roof constructions of meeting places / stadiums
- the following not predominantly statically loaded load-bearing structures or their components: walking and cycle bridges, road bridges, railway bridges, towers, masts, craneways
- Certification | Welding certificate as per DIN EN 1090-1 (steel) up to EXC3:
Conformity of the factory production control for load-bearing components and set of components for steel load-bearing structures in all types of buildings
General Building Inspection Test Certificate (abP) for all-glass railing system by MetallArt
The glass railings we offer are designed and manufactured on the basis of the standard DIN 18008-4 which applies in Germany. In order to be able to exceed the specified dimensions of individual glass panes in the standard, we have developed an all-glass railing system and obtained the approval by the German building authorities in form of a General Building Inspection Test Certificate (abP). This General Building Inspection Test Certificate was issued in Germany and is valid. It was obtained through a large number of component tests and is characterised by the integration of the glass recesses in the structurally supporting stair stringers. With this innovation, the trend to use greatest possible pane lengths for glass parapets can be met. The abP certificate is valid for all straight, curved, and rising railings made of glass.
DIN 18008 requires a glass edge protection profile on top of the glass panes that are retained at the bottom of a railing. Our railing constructions meet this requirement with a continuous filigree U-profile of stainless steel that is placed on top of the glass panes as a handrail and provides for a minimalist look.
To obtain the abP, the necessary pendulum impact tests to prove impact resistance were carried out in the laboratory in cooperation with a testing institute recognised by the German Centre for Competence in Civil Engineering (DIBt). Furthermore, an extensive structural calculation was carried out for the all-glass railing system assuming various load and installation situations.
