(Wuhan Dachu) supplies qualified barrier systems to the traffic safety area, construction industries, etc. With the strength and reputation of the Central China, Wuhan Dachu is committed to delivering quality, reliability and superior service to meet the demands of clients.

Wuhan Dachu manufacture W-Beam and Thrie-Beam guardrail to both China and abroad, and the products conforms to the requirements of different international standards, such as AASHTO Standard, AS/NZS Standard, EN Standard, etc.

W beam is the world's most widely specified safety barrier system. Highly effective and inexpensive, the most popular means of eliminating the threat from roadside hazards.Being a semi rigid barrier, W beam guardrail provides a desirable outcome for both designer and vehicle occupants. The ability of the barrier to absorb some of the crash energy reduces occupant risk and the deformation of the impacting vehicles.

Thrie-beam Guardrail An important attribute of Thrie-beam guardrail is its high level of performance especially for large vehicles. Due to the greater height of the rail face, Thrie-beam guardrail provides reduced deflection and improved resistance to vehicle vaulting or under running. The reduced dynamic deflection and maintenance demand makes Thri-ebeam guardrail ideally suited for major facilities carrying a high volume of high-speed traffic. Thri-ebeam guardrail should also be used in transition from Flex-beam guardrail to more rigid barriers. This significantly reduces the deflection of the barrier system at transition to the rigid barrier.

Transition beam-the corrugated beam used for the changeover from a Thrie-beam road safety barrier system to a W-beam road safety barrier system. Transitions are also required when Thrie-beam guardrail is terminated at a bridge abutment or a concrete parapet. The purpose of a transition is to smoothly increase the stiffness of the approach guardrail from the more flexible to the less flexible system.
