Standards ISO 9001 Joint of Poles or lattice or angular towers Lap connection or flange connection, lattice tower by bolts and nuts. Length of per section Within 14m once forming without slip joint Welding CO2, welding, Submerged  arc  welding , internal and external double welding makes the welding seam beautiful in shape      Welding Standard :AWS D 1.1 ( American Welding Society ) Thickness 1 mm to 50 mm Packages as normal cover by Mat or straw bale at the top and bottom ,we can following by client required , each 40HC or OT can load how many will calculate based on the actually specification and data. We use ISO standard, zero defects& 5S management system. When receive a new order, vice manager will organize sales, technical,procurement& logistics depart to evalue the production cycle, processing requirement, technical requirement, material supplies and other aspects to get a comprehensive analysis. Meanwhile, we should evaluate the manufacture difficulties,technique focus and product cycle therefore to make some reasonable decisions for the project that the organization, coordination will be ok to ensure the successful completion of each project.
