With the rapid development of traffic, speed enhancement, our traffic protection measures are also keeping pace with the times of rapid development and upgrading. So far our country's guardrail is roughly divided into three grades: S grade, A grade, B grade. What do these three grades represent? Below I will take you to explain the specifications of the guardrail plate and its anti-collision ability: First of all, the guardrail plate specifications are as follows: Gr-B-4E roadside B double-wave beam guardrail, column spacing 4m, driven; Gr-B-2E roadside B double-wave beam guardrail, column spacing 2m, driven; Gr-B-4C roadside B double-wave beam guardrail, column spacing 4m, concrete foundation; Gr-B-2C roadside B double-wave beam guardrail, column spacing 4m, concrete foundation; Gr-B Gr-B-2C roadside B double-wave beam guardrail, column spacing 2m, concrete foundation; Gr-A-4E roadside A double-wave beam guardrail, column spacing 4m, driven-in; Gr-A-2E roadside A double-wave beam guardrail, column spacing 2m, driven-in; Gr-A-4C roadside A double-wave beam guardrail, column spacing 4m, concrete foundation; Gr-A-2C roadside A double-wave beam guardrail, column spacing 4m, concrete foundation; Gr-A-2C roadside A double-wave beam guardrail, column spacing 4m, concrete foundation; Gr-A-2C roadside A double-wave beam guardrail, column spacing 4m, concrete foundation; Gr-A-2C roadside A double-wave beam guardrail, column spacing 2m, driven-in. Gr-A-2C roadside A-grade double-wave girder guardrail, column spacing 2m, concrete foundation; Gr-SB-4E roadside SB-grade double-wave girder guardrail, column spacing 4m, driven-in; Gr-SB-2E roadside SB-grade double-wave girder guardrail, column spacing 2m, driven-in; Gr-A-2B1 roadside A-grade double-wave girder guardrail, column spacing 2m, pre-buried socket; Gr-SB-1B1 roadside SB grade three-wave beam guardrail, column spacing 1m, pre-buried sleeve type; Gr-Am-4E median divided type Am grade double-wave beam guardrail, column spacing 4m, driven-in type; Gr-Am-2E median divided type Am grade double-wave beam guardrail, column spacing 2m, driven-in type; Gr-SBm-1B median divided type SBm grade three-wave beam guardrail. Column spacing 1m, pre-buried sleeve type; Grd-Am-2E central divider combined type Am grade double wave beam guardrail, column spacing 2m, driven type; Grd-Am-1B1 central divider combined type Am grade double wave beam guardrail, column spacing 1m, pre-buried sleeve type. The above is for you to introduce the guardrail plate 17 kinds of high-speed anti-collision guardrail plate specifications, applicable to a variety of roadway protection role. Waveform guardrail plate is semi-steel, when a group of a group of guardrail plate spliced together, and supported by the column. When received a strong external impact is, forcing the ground, columns, anti-group block, waveform guardrail plate deformation to absorb energy, which each part of the deformation can absorb strong energy. Semi-steel guardrail plate buffer capacity is greater, absorption capacity is better, and then receive a large impact will not break. High-speed waveform guardrail plate is a high-speed road, "small diamond", high-speed waveform guardrail plate for our lives and property safety has played an important role in protection.
