The choice of material for impact protection products depends on three main factors:The most critical factor is the level of performance that the collision protection needs to provide. Generally, the thicker the material and diameter, the more resistant the impact protection.Steel or plastic have different advantages and disadvantages when it comes to using impact protection in outdoor areas. Only plastic or hot-dip galvanised steel collision protection products can offer reliable protection against rust damage caused by moisture. Steel can cause damage to the protective zinc layer after collisions with vehicles, however it is preferable to plastic products for permanent UV resistance. Plastic impact protection is less durable when exposed to constant sunlight.Although steel elements are typically better at absorbing forceful impact, plastic impact protection products provide better protection for the approaching vehicle.
