Problems needing attention in selecting square pipe
1. Select materials according to the use environment: materials for square pipes include Q235, Q345, 16Mn, etc. Select suitable materials according to the use environment. If used at the seaside, choose materials with good corrosion resistance.
2. Select specifications according to load-bearing requirements: the selection of square pipe specifications should be determined according to load-bearing requirements and use environment. Generally speaking, the higher the load-bearing requirements, the larger the specifications.
3. Select the surface treatment method according to the processing requirements: the surface treatment methods of square pipes include spraying, hot dip galvanizing and electroplating. And choose the appropriate surface treatment method according to the processing requirements.
