Type IV Reflective Sheeting


DINGFEI traffic signs. Ensuring correct signage is installed on public and private roads is essential to motorist and pedestrian safety. Should an accident occur on your property with traffic signage that does not meet federal standards, owners can be held responsible. At DINGFEI, you can expect high-quality traffic signs that fulfill all federal and state requirements, regulations, and specifications. Our staff stays up-to-date with all compliance standards for signs contained in the Manual on Uniform Traffic Control Devices. To meet the reflective specifications your sign requires, DINGFEI offers engineer grade, diamond grade, and high-intensity prismatic grades of reflective sheeting.


Engineer Grade Retroreflective Sheeting

The most basic type of  retroreflective sheeting is Engineer Grade (EG), which is also referred to as Type I. EG is made up of small glass beads, which are either enclosed in a translucent pigmented substrate or two layers of prismatic sheeting. Engineer Grade retroreflective sheeting doesn’t have a distinctive pattern. It is recommended for commercial and non-critical traffic sign applications.


When EG sheeting is applied properly, it can be expected to deliver retroreflection for five to seven years. Road signs with EG sheeting are visible from 400 to 600 feet away.


Commercial Grade Reflective Sheeting

Enclosed lens reflective sheeting's. It is high quality and durable material designed for non critical traffic signage.

Best For:

i) Short Terms Advertisement Signs

ii) Stickers

iii) Number Plates

iv) Lower Speeding Traffic

High Intensity Prismatic Retroreflective Sheeting

High Intensity Prismatic (HIP) retroreflective sheeting is also referred to as ‘encapsulated lens’ sheeting. It consists of two layers: an outer translucent pigmented layer and an inner reflective layer with glass beads. The two layers are connected by a ‘lattice,’ which gives the sheeting its distinctive honeycomb appearance.

HIP sheeting is made up of prismatic cells. When a light beam lands on a sign with HIP sheeting, the light hits the sides of the prismatic cells and reflects back at a wider angle than it came. This means more light is reflected back towards the source of the light.

This type of sheeting is typically used for highway signs and when applied properly can last up to 12 years. Visibility of signs with HIP sheeting is from 800 to 1,200 feet away.


Diamond Grade Retroreflective Sheeting

The most efficient type of  retroreflective sheeting is Diamond Grade (DG). It returns 60% of the light sent its way and is designed to be used on traffic control signs. DG retroreflective sheeting is visible from between 1,300 and 1,600 feet away and can last for 12 years or longer.
