Rack decking mesh and wood decking boards are both support panels laid on beams — the former wire mesh, the latter plywood — and their load and fire performance differ markedly. Each has pros and cons in openness, cost and life; select by goods type and warehouse environment.
Wood boards are low-cost and quick to lay out, suiting goods with flat bottoms like cartons, bagged goods and palletized stock. The downsides: moisture-sensitive, prone to mildew, easy to crack under uneven load, prone to bacterial growth in oily workshops and food warehouses, and a notable fire risk.
Rack decking mesh is open, ventilated, dust-free, fire- and corrosion-resistant; the mesh lets you see the bottom of goods directly, and load distributes evenly onto the beams. The downside: it leaks tiny parts, the surface is less flat than wood, and sharp parts need a pad. Tongnuo's decking mesh distributes load evenly and suits machined and hardware parts.
Cost comparison: at the same size, mesh runs about 20%–40% pricier than wood, but wood boards need replacing every 3–5 years while mesh lasts 10+ years, so over the full life cycle mesh is cheaper. Choose mesh first in damp, oily, food and pharmaceutical warehouses.
Decision: dry, light-load, short-term turnover choose wood; heavy load, damp, fire-code and long-term use choose mesh. For something in between, lay mesh over wood boards — combining a flat bottom with openness, a compromise many warehouses use. Damaged mesh panels can be replaced singly, while wood boards are usually scrapped whole.
