As a professional manufacturer with over ten years of experience in the aluminum processing industry, Haomei Aluminum, with its profound understanding of road traffic safety, has become a recognized core supplier of road sign aluminum circles in the Asia-Africa, Middle East, and North American markets. We are not just a product provider, but a reliable partner for our clients in global road safety construction.

Our road sign aluminum circle product line covers mainstream alloy grades such as 1050/1060/1100/3003, with diameters ranging from 300mm to 1200mm, and thicknesses precisely controlled within the 1.0-3.0mm range, fully matching internationally accepted standard sizes of 600mm (prohibition signs), 800mm (warning signs), and 1000mm (instruction signs). For special scenarios, we can quickly customize non-standard diameter products to meet the differentiated needs of tunnels, highways, rural roads, etc. We also offer various surface treatment solutions, including anodizing and chemical conversion, to adapt to different reflective film lamination processes, ensuring one-stop procurement for global customers.

The quality of road signs is directly related to life safety. We have established a full-process quality control system, implementing six inspection checkpoints from raw materials to finished products.
At the raw material stage, we only use high-purity aluminum ingots that meet ASTM B209 and EN 573-3 standards, with a 100% pass rate for component testing.
During production, we use laser thickness gauges for real-time monitoring, ensuring a thickness tolerance of ±0.01mm, flatness control of ≤10μm, and no burrs or flash on the edges to ensure a firm adhesion of the reflective film.
At the finished product stage, we test indicators such as tensile strength (≥95MPa), elongation (≥30%), and salt spray resistance (≥1000 hours).
Each batch comes with a complete quality report, supporting third-party re-inspection by customers.
Our products are DOT and CE certified, and can last 8-10 years in extreme environments such as the high temperatures of the Middle Eastern desert and the humidity of the Southeast Asian rainforest, far exceeding the industry average.

Relying on 12 fully automated production lines, we have achieved full automation from aluminum coil uncoiling and precision cutting to annealing. Employing a quadruple feeding control system, raw material utilization reaches over 85%, significantly reducing waste. Modular mold design allows for specification changeover time within 15 minutes, enabling rapid response even for small-batch orders. A precise annealing process at 390-430℃ eliminates internal stress, improves material ductility, and ensures no deformation during subsequent processing. Currently, our monthly production capacity reaches 1.5 million pieces, with regular orders delivered within 7 days, fully meeting the delivery time requirements of global customers.

As a source road sign aluminium circle supplier, we reduce raw material costs through large-scale procurement, minimize labor costs through automated production, and reduce waste costs through lean management, achieving a competitive advantage of prices 10-15% lower than the industry average for equivalent quality. We also use USD for settlement to mitigate exchange rate fluctuation risks and offer flexible payment methods (T/T, L/C, D/P). For long-term clients, we have established a price protection mechanism to ensure stable supply prices during aluminum price fluctuations, helping clients improve project profit margins and enhance market competitiveness.

Our export service team has over 5 years of industry experience, is proficient in international trade rules, and can provide professional logistics solutions, supporting various transportation methods such as sea, air, and land transport to ensure safe and timely delivery of products to ports worldwide. We provide multilingual technical support in English, Spanish, and other languages to assist clients in solving technical problems. We also offer free samples to help new customers quickly verify product compatibility and reduce procurement risks.
