The netting we uses in Schools, fields, gyms depends on the size of projectiles to be stopped and can include:
1, 100/120mm mesh to stop footballs, basketball or similar kind
2, 45/30mm mesh to stop cricket balls, tennis or similar kind
3, 20mm mesh to stop golf balls or similar kind
Ceiling, roof, and wall protection netting is typically made from high-strength polypropylene (PP) & UV treated. These materials have excellent durability and load-bearing capacity.
