During vehicle inspection there is a chance of touching metal details, and if the mirror's surface is acrylic it may break. That is why you should consider choosing a mirror made of stainless steel. Stainless steel is an alloy of iron and carbon, so the mirror has high resistance to the scratches that can occur during inspection.
These mirrors are extremely durable and can last a lifetime. Because they have tensile strength they are unbreakable under tension, making them a solid alternative to acrylic and glass mirrors while providing crystal-clear reflection.
