1. High Accuracy: Laser cutting is a very precise cutting method, with cutting accuracy typically down to the micron level. This means that during the cutting of the channel, the laser beam follows a pre-set path precisely with little to no error. As a result, the dimensions of the cut channel are exactly the same as the design requirements, making it ideal for projects that require high dimensional accuracy.

2. Slag-free cutting: Laser cutting is a non-contact cutting method, whose cutting principle is to heat the channel steel material to a molten or evaporated state by means of a high-energy-density laser beam, and then blow the molten material away from the cutting gap using a gas stream. Since laser cutting involves no actual physical contact, there are no cutting tools and no tool wear or chipping. This makes laser cutting channel steel a dross-free cutting method that avoids the hassle of subsequent processing.

3. Smooth Cutting Surface: Since laser cutting does not introduce tool vibration or cutting forces, it produces a very smooth cutting surface. The cut surface is usually free of burrs, spurs or rough surfaces, which makes the cut edges of the channel very flat and neat.
