The difference between welded scaffolding and seamless scaffolding

Jun 13, 2020

1. Welding scaffolding is a hollow square cross-section steel scaffolding, also known as hollow cold-formed steel. It is made of hot-rolled or cold-rolled steel strip or coil plate by cold bending and then processed by high-frequency welding. Section steel with square cross-sectional shape and size.

2. Seamless scaffolding is a long steel bar with a hollow cross-section and no seams around it. It is a scaffold formed by extruding a seamless tube through 4 sides of a die. The scaffold has a hollow cross-section and is used as a large number of pipes for transporting fluids. Mainly used in liquid transportation, hydraulic support, mechanical structure, medium and low pressure. High pressure boiler tube, heat exchange tube, gas. Petroleum and other industries. It is stronger than welded and will not crack
