What are the advantages of seamless welded windows?

Advantages of seamless doors and windows: beautiful appearance, better sealing and sound insulation, and better waterproof.

Shortcomings of seamless doors and windows: the most obvious is cracks, and they are all different. Such as surface forming cracks, transverse cracks, solidification cracks, segregation cracks, cracks under weld bead, weld bead center cracks, etc. These reasons are related to low melting point elements. Because it is seamless welding as a whole, once cracks appear, replacement becomes very troublesome.

Secondly, the surface spraying process. Seamless welded doors and windows are welded with aluminum blanks. After welding, the surface should be painted. In many seamless welded doors and windows, there are few white and champagne colors. Seamless welded doors and windows are mostly dark series such as gray and brown. Some manufacturers just cover the surface with a thin layer of paint, which will peel after a long time.
