About this item:
The CDX Plywood 18mm – 2440 x 1220mm from DISCOUNT BUILDING SUPPLIES Ltd. is a heavy-duty sheet material designed for demanding structural applications. At 18mm thickness, this plywood offers excellent strength, rigidity, and load-bearing capacity, making it the ideal choice for flooring, decking, roofing, and construction projects where durability is essential.

The grading system means one face is “C” grade and the reverse is “D” grade, with visible imperfections that do not affect structural performance. When sealed, it can also be used in semi-exterior applications, making it a versatile and cost-effective alternative to more expensive sheet materials.
