The markings on the safety helmet contain rich and important information. The manufacturer's identification can clearly indicate the source of the product, facilitating the traceability of quality issues and after-sales service. Brand identity helps consumers identify product quality and reputation. The model identification can distinguish different styles and functions of safety helmets. The implementation of standard markings (such as GB2811-2019) indicates that the safety helmet complies with the corresponding national standards, and its various performance indicators have been strictly tested. The production date label is used to determine the service life of the safety helmet and help users replace expired products in a timely manner. These markings are important criteria for determining whether the safety helmet is qualified and safe to use.
