Description
Products Description
Plastic spray guardrail board
The plastic spraying guardrail board adopts heavy anti-corrosion treatment, and the internal coating is hot-dip galvanized layer, which has strong ability to absorb collision energy and has good line of sight guidance function. The surface coating is made of polyester powder coating, which is firmly integrated with the substrate by electrostatic spraying.
The sprayed guardrail board is mainly used for fence, decoration, protection and other facilities in industry, agriculture, municipal transportation and other industries. It has good anticorrosive properties, anti-aging and beautiful appearance. The installation is simple and fast. Good impact resistance, low cost, long life, higher safety, green environmental protection.

Working principle of spray plastic guardrail
- Spray plastic guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail plates splicing each other and supported by columns.
- It uses the deformation of soil foundation, post and beam to absorb collision energy, and forces out of control vehicles to change direction and return to normal driving direction, so as to prevent vehicles from rushing out of the road, so as to protect vehicles and passengers and reduce the loss caused by accidents.
- The spray plastic guardrail has good hardness, can coordinate with road alignment, beautiful appearance, can be used on small radius bend, and the damaged part is easy to replace.
Performance test of plastic sprayed guardrail
Impact test: no spalling and cracking.
Brine spray test: no foaming, peeling, rusting and so on.
Adhesion test: after the scratch test, the coating has no peeling off. Chemical resistance: no blasting, softening, loss of adhesion and other phenomena. High and low temperature test: no wrinkle, expansion, shedding and other phenomena. Accelerated weathering test: no large discoloration, crack, damage and other phenomena.
Manufacturing Technique
The steel strip becomes a guardrail after passing through the molding machine
After the guardrail is hoisted, it is ready to spray plastic surface treatment
Spray technology of guardrail
Guardrail loading → Pretreatment → Drying → Spraying → Curing → Cooling → Inspection →Packaging
