三种槽口各有优劣，不能简单的得出哪种好哪种不好的结论，选购时应根据要铺装的位置、面积综合考虑。如果铺装在卧室，那您可以在V型槽口地板和U型槽口地板中选择其一，因为卧室摆放了床等家具后，露在外面的面积少了很多，所以选择R型槽口的大规格地板，无异于浪费，无法实现大板的铺装效果。
The three grooves have their own advantages and disadvantages. It is not easy to draw the conclusion of which one is good or which one is bad. When choosing and purchasing the grooves, we should consider the location and area of the pavement comprehensively. If it is laid in the bedroom, you can choose one of the V-groove floor and U-groove floor. Because the bedroom has laid the bed and other furniture, the exposed area is much less, so choosing the large-size floor with R-groove is no different from wasting, and can not achieve the paving effect of the big board.
如果您的铺装面积够大，比如二十多平米的客厅，您就可以选择R型槽口的地板，它的槽口舒缓方便打理，槽口两侧的耐磨层让地板更加耐用，它的大板规格也更显客厅的大气辉煌，一定会让您和您的客人心情愉悦。
If your paving area is large enough, such as the living room of more than 20 square meters, you can choose the floor with R-groove. Its groove is relaxed and easy to handle. The wear-resistant layer on both sides of the groove makes the floor more durable. Its board specifications also show the splendor of the living room. It will certainly make you and your guests happy.
