Shanghai Metal offers a comprehensive solution for highway safety and infrastructure. We provide galvanized steel guardrails for traffic management on roads.

The most common forms of beams are the W-beam and Thrie beam types. The guardrail assemblies, available in two-wave and three-wave panels, can be paired with highway noise barriers or metal security fencing systems.

Operational Mechanism:
Steel beam guardrails are engineered to minimize harm to both the vehicle and its occupants upon impact. The wavy steel panels efficiently absorb impact energy by compressing laterally and keeping vehicles from veering off course during collisions. In the event of an accident, these guardrails assist in preventing a vehicle from skidding back onto the roadway while managing exit angles, thereby facilitating gradual deceleration and redirecting the vehicle back onto the road.

Benefits:
1) Quick repair capabilities after accidents
2) Comprehensive road safety throughout the length of the guardrail
3) Entirely galvanized steel reduces corrosion and enhances longevity
4) OEM or ODM services provided
5) Supply of posts, spacers, washers, bolts, and reflectors
6) Superior energy absorption during collisions

Railing Assembly Components:
a) Posts (C posts, U posts, H posts, Sigma posts, Flange posts, Round posts, etc.)
b) Additional Accessories (Spacers, Terminal Ends, Guardrail Reflectors, Flat Plates, Bolts, Nuts, and Washers, etc.)

THRIE BEAM GUARDRAIL – Case Study: Kuwait Al Nafae Industries

Overview

Thrie beam guardrail features three waves, enhancing its structural integrity beyond that of the traditional W-beam. This design allows for greater strength and impact resistance. It has been rigorously tested against heavy truck impacts, demonstrating exceptional durability against crash forces.

Made from high-quality materials (such as Q235, Q345, etc.) and coated with superior anti-corrosive zinc or PVC, this guardrail excels in long-lasting rust prevention. Additionally, it is cost-effective, often used as a physical barrier to prevent vehicles from leaving the roadway. Its visibility also serves as a crucial marker at transitions to high-speed roads, bridges, etc.
