Selecting the right road stud manufacturer matters. A reliable partner ensures quality, safety, and long-term value. Before you place an order, ask clear questions. Make sure the answers match your project needs. Here are 10 key questions to ask your road stud supplier:
1. What materials do you use?
Ask about the body material. Good options include aluminum alloy, PC plastic, and toughened glass. High-grade materials resist pressure, heat, and UV rays. Low-quality ones fade, crack, or deform over time.
2. What is the load-bearing capacity?
Heavy trucks, snowplows, and daily traffic apply pressure. Ask how many tons each stud can handle. Most roads need studs that support over 20 tons. Highways and airports need over 30 tons.
3. What waterproof level do your studs meet?
Water enters cheap studs easily. Good products should reach IP68 or higher. This protects the circuit and battery from rain, snow, and flooding. Poor waterproofing causes failure in harsh weather.
4. How far is the visible distance?
Brightness keeps drivers safe. Ask how far the LED or reflector can be seen at night. Good solar studs offer visibility from 500 to 1000 meters. Dim lights fail to warn drivers in time.
5. What type of LED and battery do you use?
Ask about LED quality and brightness. Taiwan Epistar or other high-end LEDs work well. Battery type matters too. Lithium and Ni-MH batteries last longer and perform better in hot and cold weather.
6. How long does the stud operate after charging?
Charging time and working duration affect performance. Ask for flashing and steady mode durations. Good studs run over 200 hours in flashing mode and 100 hours in steady mode after full charge.
7. Can I customize colors, size, and function?
Projects need different specs. Ask if the factory offers OEM or ODM services. Some jobs need special shapes, colors, or sync flashing features. Custom options help you meet local standards and client needs.
8. What certifications do you have?
Ask for CE, ROHS, ISO, or national standard certifications. These prove the product meets safety and quality standards. Also, ask for test reports, such as compression and waterproof tests.
9. What is the product lifespan?
Ask how long the road stud can work under normal use. Materials, battery, and solar panel all affect lifespan. Good products can last 3 to 5 years. Cheaper models fail faster and cost more over time.
10. What after-sales support do you offer?
Things can go wrong. Ask if the company offers warranties, technical guidance, or replacement service. A good supplier supports you even after the sale. That saves time and builds trust.
Asking smart questions helps you find the right road stud manufacturer. Focus on quality, durability, and service. Don’t choose only by price. A strong product keeps roads safe and reduces maintenance. Use this list. Make the best choice.
