Installation Instructions

Prior to installation, check with your local regulatory agency for special coding requirements in your area. The purchaser is solely responsible for compliance with applicable local codes. We recommend checking with a licensed architect engineer or local building official before installation.

Recommended tools: Circular saw (carbide tipped with less than 20 teeth is prefered), carpenter's level, tape measure, corded or cordless drill

Joist span: 16-inch center to center joist span is recommended for residential installation. 12-inch center to center joist span is recommended for commercial installation. When installing boards at 45-degree angles, 12-inch center to center joist span is recommended.

Installing Decking
As illustrated, there are two methods to install deck board. Method-1 is the traditional one, while Method-2 taking advantage of Cellek™'s fastener & groove system eliminates pre-drilling and enables faster installation as well. You may fasten the outside edge of the first board to deck with screws. Then from the second board, you can just use Cellek™ fasteners to secure each board onto the joists underneath at the intersection.Cellek™ fastener will automatically maintain an identical spacing between each board. When apply a screw through the fastener, you need to makesure that the screw head is relativelyflush with the fastener; and never over tighten screwsand bow fasteners. Thefastener's long edge must remain parallel tothe deck board so thenext deck boardwill fit snugly. Repeat the sameprocess for each board until the outside edge of the last board is fastened with screws.



Gapping Gaps between decking boards allow water to drain off and also for the slight thermal expansion. A gap of 1/8" to 1/4" is recomanded. Cellek's groove & fastener system will provide a uniform spacing between deck boards.

End-to-end & Abutting gap Deck boards must be gapped end-to-end, based upon the temperature at installation. See chart on right. When deck boards are abutting a wall or a solid objects, gapping is also required. The gapping could be a half of the end-to-end gapping.

Stairs Traditional stairs require at least four stringers for a 36" wide stair.
