Nine-fold profiles and sixteen-fold profiles refer to the column and beam structures of cabinets named for the number of bends. The nine-fold profile and sixteen-fold profile are closed column and beam structures, which have higher strength and greater force than the traditional open beam and column and C profile structures.
If only from the perspective of force, the sixteen-fold profile is obviously better than the nine-fold profile, on the one hand, because the load-bearing of the beam and column is determined by the cross-sectional area of the beam and column, and the larger the cross-sectional area, the better the load-bearing. On the other hand, the more bends, the same material is equivalent to more stiffeners. However, the application of nine-fold profiles is also very extensive, because the cost is low, the beam and column occupy a small space, and it is favored by users.
As for which is good, it depends on your needs.
