How do you determine the Highway Road Barrier Guardrail Price?

The price of highway guardrails depends on key factors such as W Beam thickness (typically 3.0 mm or 4.0 mm), zinc coating weight , and required standards like ASTM A36 or AASHTO M180. It may also vary based on order quantity, surface treatment, and whether accessories are included. Please provide your project specifications (dimensions, standards, quantity), and we will offer a precise and competitive quotation.

Can samples be sent before placing an order? What are the costs?

Yes, we can send guardrail samples free of charge; you only need to cover the shipping costs.

What is the lead time for the guardrails?

The standard production cycle for guardrail kits is approximately 5 to 35 days; the final delivery time will depend on the type and quantity of the guardrail order.

AI-Powered supplier vetting

SummaryThe supplier operates in metal products, steel processing, traffic and public-administration signage, traffic-safety equipment, metal structures, and high-performance fibers and composites. It holds ISO9001:2015 and CE certifications, reports documented procedures for service assessment, corrective actions, and complaint handling, and has six to ten quality-control staff. The supplier demonstrates customization capability and reports new products within the past year, but does not provide ODM services, SDKs, overseas warehouses, showrooms, agents, or branches. Financial information is limited to year labels without substantive performance figures, so financial credibility cannot be determined. No Fortune 500 cooperation or well-known-brand OEM experience is reported. Production scale, capacity, and customer references are not sufficiently evidenced.

Supplier typeThe supplier is a manufacturer and seller covering metal structures, metal materials and products, steel rolling, traffic and public-administration signs, traffic-safety equipment, mechanical and electrical equipment, and high-performance fibers and composite materials. The stated scope also includes goods import and export, indicating both manufacturing and trading activities.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification. These are explicit certifications relevant to quality management and product conformity, although the supplied information does not specify their scope or validity dates.

After-Sales capabilityThe supplier has written and followed procedures for service-capability assessment, corrective and preventive actions, and customer complaint handling. However, it has no overseas warehouse, showroom, agent, or branch, and reports zero countries with overseas services, which limits documented overseas service coverage.

R&D capabilityThe supplier reports two years of total R&D engineer experience, one national science and technology progress award, and new products within the past year. It does not provide an SDK and does not offer ODM services, so the evidence supports some innovation activity but not broad software or ODM capability.

Production capacityThe supplier lists multiple manufacturing activities, including metal products, steel rolling, signage, traffic-safety equipment, metal structures, and composite materials, and reports six to ten quality-control staff. Lead times are stated as within 15 working days in both peak and off-season, but production capacity, equipment, output, and facility scale are not provided.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. This directly supports a broad product-customization capability, although ODM service is specifically unavailable.
