Traffic warning sign materials

Many people are unaware of the names of the traffic warning signs they see on the road. Although some refer to them as “blue signs“, Qixiang will tell you that they are actually known as “road traffic signs” or “traffic warning signs”. Additionally, some people want to know what kind of material is used to make the typical blue traffic warning signs. Qixiang will respond to that for you today.

Reflective film, aluminum plates, clamps, tracks, and posts make up road traffic signs. We’ll give you a thorough overview of their materials today.

I. Traffic warning sign Materials – Reflective Film Materials

Class I: Typically a lens-embedded glass bead structure, called engineering-grade reflective film, used for permanent traffic warning signs and work area facilities.

Class II: Typically a lens-embedded glass bead structure, called ultra-engineering-grade reflective film, used for durable traffic warning signs and work area facilities.

Class III: Typically a sealed capsule-type glass bead structure, called high-intensity reflective film, used for permanent traffic warning signs and work area facilities.

Category IV, typically with a microprism structure, is called high-intensity reflective film and can be used for permanent traffic warning signs, work area facilities, and delineators.

Category V, typically with a microprism structure, is called wide-angle reflective film and can be used for permanent traffic warning signs, work area facilities, and delineators.

Category VI, typically with a microprism structure and a metallic coating, can be used for delineators and traffic bollards; without a metallic coating, it can also be used for work area facilities and Traffic warning signs with few characters.

Category VII, typically with a microprism structure and flexible material, can be used for temporary traffic warning signs and work area facilities.

II. Traffic Warning Sign Panel Material – Aluminum Plate

1. 1000 Series  Aluminum Sheets

Represents 1050, 1060, 1070.

1000 series aluminum plates are also known as pure aluminum plates. Among all series, the 1000 series has the highest aluminum content. Purity can reach over 99.00%.

2. 2000 Series Aluminum Sheets

Represented by 2A16 (LY16) and 2A06 (LY6).

The 2000 series aluminum sheets are characterized by high hardness, with copper content being the highest, approximately 3-5%.

3. 3000 Series Aluminum Sheets

Represented primarily by 3003 and 3A21.

Also known as rust-proof aluminum sheets, my country’s 3000 series aluminum sheet production technology is quite advanced.

4. 4000 Series Aluminum Sheets

Represented by 4A01.

The 4000 series aluminum sheets have a high silicon content, typically between 4.5% and 6.0%.

Qixiang, as a source factory, directly supplies traffic warning signs, covering all categories including warning, prohibitory, instruction, directional, and tourist area signs, suitable for municipal roads, highway intersections, industrial parks, parking lots, and other scenarios. Custom patterns, sizes, and materials are supported! We use national standard aluminum sheet as the base material, coated with imported reflective film, which has high reflectivity, strong nighttime visibility, UV resistance, and is resistant to wind and rain, and does not easily fade or age. Equipped with thickened grooves, clamps, and other accessories, it ensures a secure installation and is compatible with various light poles and columns. We have our own large-scale CNC cutting and coating production line, ensuring high precision and sufficient production capacity, and we support rush orders.

Qixiang has complete qualifications, meets national road traffic safety facility standards, and provides one-stop service from design, production, to delivery. Wholesale prices are competitive, and discounts are available for bulk orders.
