Detecting the squareness of EN 10210 S355J0H rectangular tubes involves three methods:

1. Diagonal method: Ensuring equal diagonals, but as discussed in the adjustment of EN 10210 S355J0H rectangular tubes - diagonal section, confidence in diagonal measurements is not high due to factors like actual corner size and measurement position.

2. Protractor measurement method: Placing one edge of the protractor against the tube surface and moving it up and down until the other edge touches any point on the tube surface, checking for light leakage. However, this method requires a flat measurement surface and emphasizes concave rather than convex surfaces.

3. "Twin inspection method": When a protractor is not available, two segments can be cut from the same rectangular tube, cleaned of burrs at the ends, placed facing each other or opposite each other (with the weld as a reference), placed on a platform, slowly brought together, and judging the squareness of the tube based on the gap position after coming together.
