Producing large castings with perfect surfaces is a difficult task. The larger the surface area, the more likely there is to be some air pockets or voids during the casting process that only show up after machining.

Our castings are optimized to produce a high quality top surface, but even a typical table will often have some small imperfections on the top or side of the machined surfaces.

When the tables experience a higher number or severity of surface defects we designate them as factory seconds and sell them at a discounted price.
