Inspect the surface for any cracks

To discern the quality of collision barriers, one can also inspect their surface for cracks. Bridge railings should be determined based on the highway grade, considering factors such as safety, coordination, the characteristics of the objects to be protected, and the on-site geometric conditions, among others, to decide the collision resistance level. Then, the construction form should be selected based on its inherent structure, economy, and factors such as construction and maintenance. The collision barriers in question have a surface that is intact and free of cracks. In contrast, low-quality collision barriers, made from earthenware material, often result in cracks during the production process.

2. Observe the cross-sectional shape

Upon a close examination of the cross-section of the collision barrier, one can discern the capabilities of the manufacturer. A collision barrier producer that pays attention to production techniques boasts a cross-section that is exceptionally smooth, free from any unevenness.
