XTrays flood tables and grow trays are manufactured with durable, high impact ABS plastic. Made in Canada at their cutting edge thermoforming facility, XTrays are of the highest quality and a level of durability unmatched in the industry. By choosing to use high impact ABS instead of the more common, lower grade, HIPS (Styrene), XTrays can easily withstand temperature fluctuations and the hazards of daily agricultural use.
