All columns, trusses and other components and joints are processed and welded first, and then hot-dip galvanized;

Site assembly, no welding.Metallic coatings-- Hot dip galvanized steel all other steel parts and fasteners shall be made according to GB/T 13912-2002 Metallic coatings-- Hot dip galvanized steel

The connecting fixed parts are mainly used in line with GB5782 standard and are treated by hot dip galvanization. The service life of the main structure of greenhouse is not less than 25 years.
