Abaco™ tropical hardwood decking, from Aljoma Lumber, features a contemporary European design with a traditional smooth finish on one face and an elegant moulded surface on the other. The moulded surface makes each board slip-resistant and cooler on the feet. Abaco is available in grooved and traditional boards. Abaco's grooved deck board has slotted sides for quick and easy installation using hidden fasteners. Hidden Fasteners help gap each board with the proper spacing and allow for natural expansion and contraction.
