North American ATH

     With advancements in veining techniques, demand for surfacing with a veining feature is growing. This trend can be seen as many of the leading surfacing companies have continued to introduce translucent, veined designs similar to natural onyx.
The R.J. Marshall Company offers a full line of high quality Onyx fillers carefully controlled for consistency and designed to give optimal performance and beauty.

     The Dense Fill series of White Alumina Trihydrate offers excellent stain resistance, easy wet-out and rapid air release properties. These products are easy to pigment, allowing the creation of a wide range of Solid Surface colors for custom applications. As in all ATH materials, meeting Class I flame and smoke requirements is an added benefit.


The R.J. Marshall Company operates six (6) manufacturing/warehouse locations throughout the United States. Onyx Fill and Dense Fill products are manufactured at our  Erie, Michigan  location.
