All of our corrugated steel beam guardrails at Zhengda are manufactured in-house to ensure the highest quality control in our production processes. To begin our production, we purchase the highest quality goods, i.e., carbon steel, and zinc steel. These materials are the highest of quality and are the strongest and most resistant to corrosion. We utilize the best automated production lines in the industry, where we perform laser cutting and CNC machining to achieve the best quality guardrails. To ensure the protection of all future users of our guardrails, we complete a large variety of safety tests to ensure their safety in varied environments. These environments include, but are not limited to, highways and construction sites. We are the most innovative business in the sectors we work in, exemplified by our nearly one hundred patents for prefabricated drive guardrails. We work hard in our industry, and this results in great support for our international customers to ensure that and safety through quality guardrails that are durable. A great additional technical automation is provided in the assembly of the guardrails, as well as their ongoing routine maintenance.
