Building materials like paints, wallpapers, timber, sheet materials, ironmongery, adhesives, bricks, blocks, drainage pipes, aggregates, bagged materials, and glass each have specific storage requirements due to factors like chemical makeup, breakability, and regulations. Poor storage can cause issues like materials becoming unusable, contamination, or safety hazards. Proper storage is important to keep materials in good condition until they are ready for use on a construction site.
