3.Advantages of Huashida stand

The steel pipe stand can be installed within an error range of ± 80mm of the user's ground foundation. The height of the stand is adjusted by anchor mounting bolts. When installing the stand, a slope of 5 ‰ is reserved, making it easy to roll large pipe diameters. Reduce labor intensity. After the installation of the platform frame, the foundation of the platform frame shall undergo secondary grouting treatment, with a neat and generous appearance
