One Aluminum Plate, Supporting All-Weather On-Site Safety
Whether a warning sign can withstand the site often depends not on the light, but on the body. The LED Arrow Board uses a one-piece bent aluminum alloy plate to build its main structure, solving from the material source the problems of traditional warning signs — easy rusting, easy deformation, and bulky handling — allowing the device to operate stably for long periods in rain, snow, fog, severe cold, and heat.
Material Analysis: Aluminum Alloy Plate Body
One-Piece Bent Forming for a Stronger Structure
The main body is formed from a single aluminum plate through one-piece bending, reducing seams and welding weak points. It offers high overall strength and strong deformation resistance. Whether during transport vibration, on-site impacts, or long-term outdoor use, the body is less likely to loosen or deform.
Aluminum Alloy Material — Both Lightweight and Strong
Aluminum alloy has low density and high strength. While ensuring structural rigidity, it keeps the total weight at 3KG, allowing one person to carry and move it — balancing durability and portability.
Anti-Rust Electrostatic Spraying for Stronger Weather Resistance
The aluminum plate surface undergoes anti-rust electrostatic spraying, forming a uniform and dense protective layer that effectively resists moisture, salt spray, and UV erosion. It is rust-proof, waterproof, and fog-resistant, and won't easily fade, peel, or rust during long-term outdoor use.
Independently Sealed Core Components for Thorough Protection
Beyond the aluminum plate body, the core circuits and battery box use an independent sealed design, effectively isolated from the external environment to prevent moisture and dust intrusion, forming double protection with the aluminum shell.
Wide Temperature Range for Harsh Environments
The aluminum plate structure combined with the sealed design allows the product to operate stably across -20℃~+60℃, remaining reliable in rain, snow, haze, and high-temperature exposure.

Beyond Material, Equally Outstanding
Dynamic LED Illuminated Warning
High-brightness red LEDs with a light guide plate and high-transmittance lens are clearly identifiable from over 500 meters away. Three modes — Steady, Fading, and Flashing — switch according to day/night and road conditions.
DC/AC Multi-Path Power Supply
Supports DC, AC, and solar power with a built-in high-performance battery. Connect to power where available; rely on solar where not — for 24/7 continuous operation.
Four Installation Methods
Choose from wall-mounted, hanging, independent placement, and vehicle-mounted. Used with Truck-Mounted Attenuators (TMAs), it forms integrated "Cushion + Warning" protection.
Low-visibility warnings in rain, snow, fog, and at night
Mobile operations for maintenance, patrol, and rescue
Long-term guidance at fixed construction sites
Integrated protection for high-risk highway operations

FAQ
Q1: What material is the body made of?
A: Aluminum alloy plate, one-piece bent forming, with anti-rust electrostatic spraying on the surface.
Q2: What are the advantages of the aluminum plate body?
A: One-piece bending reduces seams for a sturdy, deformation-resistant structure. Lightweight aluminum alloy keeps the total weight at only 3KG, allowing one-person handling. Anti-rust spraying is waterproof, rust-proof, and fog-resistant for greater durability in long-term outdoor use.
Q3: Will it let in water or rust in harsh weather?
A: No. The aluminum shell is rust-proof, waterproof, and fog-resistant, and the core circuits and battery box are independently sealed, forming double protection for stable operation across a wide temperature range of -20℃~+60℃.
Q4: What are the advantages of dynamic illuminated warning?
A: High-brightness red LEDs actively illuminate, combined with a light guide plate and high-transmittance lens, making it clearly identifiable from over 500 meters away. Three modes — Steady, Fading, and Flashing — can be switched according to day/night and road conditions, making it more striking than traditional static reflective signs.
Q5: What if there is no mains power on site?
A: It supports multiple power options — DC, AC, and solar — with a built-in high-performance battery. Where mains power is available, connect to AC; where not, rely on solar charging or DC power for 24/7 continuous operation.
Q6: Where can it be installed?
A: Supports four installation methods — wall-mounted, hanging, independent placement, and vehicle-mounted. Used with Truck-Mounted Attenuators (TMAs), it forms integrated "Cushion + Warning" protection, suitable for road construction, traffic control, mobile operations, fixed construction sites, and more.
Q7: How heavy is it? Can one person operate it?
A: Weighs only 3KG with a portable handle; one person can carry and deploy it in seconds without lifting equipment.
Q8: What are the purchasing and delivery details?
A: Brand: Riminghuan; Place of Origin: China; MOQ: 10 units; Delivery Time: 30 days; Payment Terms: EXW; Packaging: wooden box or cardboard box. Orders are typically processed within 1-2 business days.
