When fire engines, ambulances and police vehicles are carrying out emergency tasks, they require the highest level of passive safety warnings. Our diamond-grade reflective stickers employ micro-prism technology, with an inverse reflection coefficient of over 700 cd/lux/m², which is 7 times that of engineering-grade products. They can be clearly detected by drivers from a distance of 1 kilometer. The product complies with the strict requirements for reflective signs in the NFPA 1901 standard (fire vehicle safety standard). The base material is made of ultra-flexible polycarbonate layer, which can closely fit the curved cabin and protruding rivet areas. It maintains good flexibility even in low-temperature environments and does not crack. The accompanying pressure-sensitive adhesive has high strength and can firmly adhere to metal, fiberglass-reinforced plastic and composite material surfaces for a long time. The product offers standard emergency service colors such as red, yellow, white, and fluorescent yellow-green, with a width customization range of 5 cm to 30 cm. Installation is recommended to be carried out using a heat gun with a dedicated tool to ensure no bubbles on complex curved surfaces. Each roll of product comes with a reflective performance test report. For B-end emergency vehicle modification factories and government procurement suppliers, we provide bulk discounts and rapid delivery solutions to help you win institutional large customers.
