Today, most global road infrastructure projects, highway expansion and renovation projects, rural road lighting projects, and port and industrial park renovation projects opt to purchase Chinese solar road studs. With a mature domestic transportation infrastructure supply chain, outstanding value for money, and strong customization capabilities, China has become the preferred sourcing destination for overseas contractors and distributors. However, the industry is a mixed bag, with frequent incidents such as trading companies posing as original manufacturers, falsifying product specifications, compromising waterproofing and compression resistance, and forging certifications.
Many overseas buyers and general contracting teams frequently encounter problems after making purchases: road studs short-circuit when water enters during rain, shatter under heavy loads, fail to provide sufficient runtime during overcast or rainy weather, and experience rapid brightness degradation. This not only renders road warnings ineffective and necessitates project rework and rectification but also leads to a series of issues, including failed inspections, customs clearance delays, and after-sales service evasion. To mitigate procurement risks and secure stable, durable, compliant, and standard-meeting engineering-grade products, the key lies in identifying truly reliable original manufacturers. Drawing on practical industry procurement experience, this article shares a comprehensive process for manufacturer screening, qualification verification, product testing, and avoiding pitfalls in collaboration. It also analyzes the core advantages of HOAN Traffic as a legitimate original manufacturer, providing professional guidance for global road project procurement.
Many buyers tend to overlook differences in supplier types, blindly comparing prices and placing orders, which ultimately leads to project losses. There is a vast difference between working with trading intermediaries and genuine source manufacturers, and this disparity is the root cause of unstable product quality. Most intermediaries lack independent production, quality control, and R&D capabilities; they merely resell products to earn markups and cannot control the finer details of the manufacturing process. When faced with batch defects, customization requests, or after-sales issues, they are highly prone to passing the buck and failing to resolve problems.
In contrast, legitimate source manufacturers possess complete production lines, aging test equipment, quality inspection systems, and technical teams. From raw material procurement, production and assembly, sealing processes, to final factory testing, the entire process is controllable and traceable, ensuring higher product stability and consistency. Additionally, source manufacturers support customized modifications, stable bulk delivery, and comprehensive after-sales warranties, enabling them to meet the demands of complex engineering scenarios such as overseas municipal tenders, heavy-duty highway applications, coastal salt fog environments, and foggy mountainous regions. For customers involved in long-term road project operations and maintenance, bulk procurement, or customized requirements, selecting a reliable source manufacturer is key to reducing full-lifecycle procurement costs and mitigating project risks.
To quickly screen for reliable Chinese solar road stud manufacturers without resorting to blind trial and error, follow these six standardized verification steps to easily distinguish genuine from counterfeit suppliers and identify high-quality partners.
The first step in identifying a supplier is to distinguish between source manufacturers and trading companies. Legitimate manufacturers possess physical factory premises, standardized production workshops, and complete production lines, and can provide a full set of documentation, including actual photos of the workshop, videos of the production process, factory certifications, and business licenses. They also possess years of experience in the R&D and production of traffic infrastructure, independently completing the entire production process—including die-casting, assembly, resin sealing, and aging tests. In contrast, most trading companies only have product images but lack actual production footage or process records, and cannot provide materials for on-site verification; therefore, careful scrutiny is essential during procurement. HOAN Traffic has been deeply involved in the road safety equipment sector for 15 years. As a physical source factory specializing in solar road studs, reflective road studs, and traffic signals, its production capabilities and capacity are stable and verifiable.
Overseas road projects and cross-border procurement impose stringent requirements on product qualifications; products without proper certifications will directly result in failed customs clearance and project acceptance. A reliable manufacturer must possess a complete set of compliance certifications, including CE and RoHS international certifications as well as ISO 9001 quality management system certification. Additionally, they should be able to provide third-party test reports verifying IP68 water resistance, heavy-load compression resistance, and weather resistance, ensuring full compliance with global road construction standards and tender requirements. When procuring, do not rely solely on verbal claims regarding certifications; always request original certification documents and verifiable reference numbers to eliminate the risk of counterfeit certificates.
No matter how impressive the product specifications may be, nothing is more persuasive than the actual results from completed projects. A high-quality manufacturer will inevitably have a wealth of completed projects both domestically and internationally, and can provide actual project photos, engineering feedback, and collaboration records from diverse scenarios such as expressways, mountainous fog-prone areas, coastal salt fog environments, rural roads, and port and industrial zones. By reviewing project case studies under similar operating conditions, you can intuitively determine whether the manufacturer’s products are suitable for complex and harsh environments and whether they can reliably withstand frequent engineering challenges—such as heavy-load rolling, prolonged rain, and salt fog corrosion—thereby avoiding mismatches between the product and the project’s actual conditions.
This is the most critical step to avoid pitfalls in overseas procurement; never place large bulk orders directly. Reputable source manufacturers all offer free sample requests and small-scale field testing. Buyers can use samples to simulate real-world operating conditions: test water resistance through rain immersion, assess compression strength under heavy loads, and simulate battery life in overcast or rainy weather by keeping the samples away from light. At the same time, verify details such as light brightness, flashing modes, and housing materials to accurately judge the product’s true quality, eliminate issues like inflated specifications and compromised quality, and mitigate bulk procurement risks at the source.
Different countries and road projects have varying requirements for road studs, including light color, flashing modes, housing logos, packaging specifications, and installation dimensions. Reliable manufacturers possess mature OEM and ODM customization capabilities, allowing them to adjust product specifications, appearance, and lighting modes according to customer needs to meet various customized engineering requirements. In contrast, small workshops and middlemen lack customization capabilities and can only provide standardized finished products, failing to meet the detailed and personalized requirements of project implementation.
For bulk engineering procurement, it is essential to confirm the manufacturer’s minimum order quantity (MOQ), standard production lead times, inventory and production capacity, and after-sales warranty terms. High-quality factories have sufficient production capacity, stable lead times, and the ability to handle orders of all sizes, while also providing clear written warranty policies that specify services such as replacement for defective units, after-sales repairs, and technical support. Avoid suppliers who offer only verbal warranty commitments without written documentation to prevent situations where product failures later result in no after-sales support or no recourse for rights protection.
When selecting manufacturers, it is crucial to thoroughly verify the product’s core performance metrics. High-quality engineering-grade solar road studs must meet multiple mandatory standards. Regarding protection ratings, projects on highways, in rainy regions, or in coastal areas must use products with genuine IP68 fully sealed waterproof construction, avoiding products falsely labeled as IP65 or IP67, to ensure long-term resistance to rain immersion and dust accumulation. Regarding materials and compression resistance, cast aluminum one-piece housings are preferred for main thoroughfares. These are impact-resistant and corrosion-resistant, capable of withstanding repeated rolling by heavy-duty trucks without cracking or deforming.
For energy storage and battery life, the products must be equipped with high-efficiency solar panels and long-lasting lithium batteries to ensure high charging efficiency and sustained operation during overcast or rainy weather, making them suitable for long-term, stable operation in foggy and rainy regions. Lighting performance must meet long-distance visibility requirements and support multiple modes—including constant-on, slow and fast flashing, and synchronized strobe—to comply with traffic regulations in different countries. The entire HOAN Traffic line of solar road studs meets or exceeds the above engineering-grade specifications, offering stable performance and accurate specifications, making them fully suitable for all types of high-standard road engineering projects.
During overseas procurement, most issues stem from common industry pitfalls. First is the “rock-bottom price” trap: products priced far below the industry average inevitably suffer from compromised materials, falsified specifications, substandard batteries, and simplified sealing processes. These result in extremely high failure rates later on, with total O&M costs far exceeding the initial price difference. Second, some traders pose as manufacturers—lacking actual production capacity, quality control systems, and after-sales support.
At the same time, be wary of schemes involving forged certifications and fake test reports; always verify the authenticity of certificates. Avoid blind purchasing by placing bulk orders without first conducting sample testing. Reject vague warranty terms—all after-sales service, warranty coverage, delivery schedules, and customization requests must be documented in writing to prevent future disputes and comprehensively safeguard your procurement rights.
