A 150 × 25 mm solid straight-grain WPC decking board, co-extruded in one piece from wood-plastic composite, weighing a solid 4.494 kg per metre (core density around 1.20 g/cm³, standard formulation, tightly packed) — the widest-faced board in the solid straight-grain range. At 150 mm it is the broadest face in the whole range, and the arithmetic is simple: the fewest boards and the fewest seams per square metre. Fewer seams means the deck reads as one continuous sheet of timber rather than a set of strips clipped together, and the install side benefits just as directly — fewer cuts, fewer clips, fewer man-hours, the highest coverage rate on large areas. The 150 × 25 solid straight-grain board is for the briefs that ask for one unbroken surface, a modern face and easy upkeep — the workhorse for premium residential gardens, terraces, guesthouses and boutique commercial spaces.
