We are often asked if our bases are strong enough to support granite or solid stone table tops, however many times it is not the weight of the table top that is the issue. The high quality 304 grade stainless columns we supply have a crush capacity of up to 10 tons.
The three factors that must be taken into consideration when determining if the base and the top are compatible are;
1) what is the ratio of the top size in comparison to the base
2) how heavy is the base in relation to the top and
3) how long is the column of the table base?
TABLE TOP SIZE TO TABLE BASE SIZE RATIO If the tabletop size is too large there is a danger of the table toppling over. When using heavy table tops such as granite, it is wise to use a larger base. Remember also to choose a base that can accommodate a chair still being pushed in far enough under the top. Table bases with multiple columns add greater stability to heavier tops. There will be less column shake or flex than with a single column design.
WEIGHT OF THE BASE VS. THE WEIGHT OF THE TOP. The weight of a table base must also be taken into consideration when choosing a table top. A light weight table base would not be a suitable option to pair with a granite or stone tabletop. Even if the top size to base size ratio is good, it is normally not recommended, as the risk of the table top being too top heavy is too high. A base with a heavy bottom plate such as our RFL and RSQ series bases in stainless or black powder-coat are a good choice for heavier table tops.
LENGTH OF THE TABLE BASE COLUMN. Taller tables (such as bar height) will also require a heavier and larger base because the taller the table is, the less stable it becomes.
