The difference between pressed paving bricks and strong extruded paving bricks
As far as outdoor floor tiles are concerned, pressed paving bricks strictly speaking cannot be used for outdoor floor paving. Its advantage is that the density of the bricks is relatively low and the bricks are loose and can play the role of thermal insulation (such as refractory bricks). Therefore, when used on outdoor floors, they cannot play the role of pressure resistance, wear resistance, and frost resistance.
For strong extruded paving bricks, it is specially used for outdoor floor paving. The advantages are high brick strength, good wear resistance, and strong frost resistance, which are fully consistent with the performance requirements of outdoor floor tiles.
