The new type of scaffolds from YanDa are made of high-quality steel and manufactured with electronic control digital welding equipment. Typically, the incoming raw materials will be strictly inspected. Before processing, all the components and parts of scaffolds will go through certain mechanical processes, following the instructions of the blueprints, and then we will weld the components and parts together while assuring the structure and quality of scaffolds comply with the blueprints strictly as well. After welding, the products will experience hot-dip galvanizing anti-rust treatment processes, including hot-dip galvanizing, electro galvanizing, power spray, spray painting, etc., which are complied with ISO quality management system standards. To ensure the quality of products, finally YanDa will run strict inspections and tests, for example, we will erect scaffolds to make sure the products are precisely manufactured.
