What are the aluminum plate thickness and reflective film levels for traffic sign posts?

As a core component of traffic sign posts, the aluminum plate thickness and reflective film grade on the signboards are categorized accordingly, with different grades naturally serving various functions. Below, a professional manufacturer provides a detailed introduction to the aluminum plate thickness and reflective film grades of traffic sign posts. Come and learn about them in detail together.

Category 1 typically features an embedded lensed glass bead structure, known as ultra-engineered reflective film, with an expected lifespan of 10 years. It is suitable for durable traffic sign and work zone equipment.

Category 2, typically featuring a microprismatic structure with a metallic coating, has a service life of around 3 years and is suitable for regulatory signs and traffic poles. It can also be used for equipment in work zones and signs with fewer characters when not coated with metal. Category VII, generally microprismatic and made of flexible materials, also has a service life of approximately 3 years and is used for temporary traffic signs and equipment in work zones.

Three types, typically microprismatic in structure, are known as reflective sheeting. Their lifespan is generally around 10 years and they are suitable for road signs, work zone equipment, and summary markers.

Category 4, general sealed capsule-type glass bead structure, known as reflective film, has an average lifespan of 10 years and is suitable for traffic signs and work zone equipment.

Five types, typically featuring a micro-prismatic structure, are known as high-angle reflective film, with an average lifespan of 10 years. They are suitable for traffic signs, work zone equipment, and summary markers.

6 types, typically lens-embedded glass bead structures, known as engineering-grade reflective film, have an expected lifespan of 7 years and are suitable for traffic signs and work zone equipment.
