Truss truss industry safety standards

I. Refer to EU mandatory standards. The CE certification contains specific criteria for truss trusses. The European Commission issued a number of CE mark directives/standards updates and expanded the relevant certification requirements, including the European Union EN 1090 steel (aluminum) structure manufacturing certification standards. Mandatory manufacturers in the welding system certification, most domestic manufacturers can not meet this requirement, only Yaona and other professional manufacturers can meet this requirement. Of course, the difficulty is also divided into different levels.

Second, the German TUV and other professional third-party testing agencies certification. Including many aspects of truss truss certification: such as truss truss load test, truss specific process assessment (welding and other processes).

Third, the ISO system certification (pay attention to the qualification and reputation of the certification body), the use of materials testing certificates, business licenses and other licenses.
