RoyalStone™ Synthetic Stone Column Covers
RoyalStone™ synthetic stone columns are offered in 6 standard colors which fully permeate the column. In other words, the stone-like appearance isn’t skin deep; the color pigment is absorbed by every particle of the column. In addition to our standard colors, we are virtually unlimited as to the colors that we can produce. Typically our columns come in one uniform color; however, we are able to mix in various aggregates to achieve a “dirtier” stone look. The majority of our columns are lightly textured using a sandblasting method but we also offer a smooth finish and even a coral finish where actual coral aggregate is used to create a load-bearing coral column. These columns are roto-cast resulting in a load-bearing yet hollow column. RoyalStone™ columns typically use calcium carbonate filler, which is fine particles of crushed rock that when mixed with polyester resin solidify or harden to form a robust man-made stone column. Since RoyalStone™ is predominately used as exterior columns, they typically do not require an ASTM E 84 Class A test method for flame spread and smoke density. However, if a project calls out for polymer stone columns with a Class A rating, we add Alumina Trihydrate “ATH” to the matrix in order for the columns to pass the smoke density portion of the test. Without the ATH, the columns would pass only the flame spread portion of the test. These columns typically weigh from 60 lbs. to 4000 lbs., depending on the size of the column. This is considered a lightweight alternative when compared to natural and cast stone but if even lesser weights are required, we can substitute lightweight filler which will decrease the weight of the column by a factor of 2. For example, a column weighing 300 lbs. would now weigh 150 lbs. In essence we offer “lightweight stone columns” but can offer “very lightweight stone columns”.
