Industry Application
Proving Grounds and Test Tracks
A vehicle proving ground puts barrier on banked curves and high-speed loops where the geometry is continuously curved and the tolerance for a poor fit is low. Straight sections chorded across a curve leave gaps and leading edges. Hongda has supplied barrier for automobile proving ground projects, and the curved radius guardrail is bent to the alignment rather than forced to follow it.
The Problem
Industry Pain Points
- Straight barrier sections chording across a continuously curved alignment
- Leading edges and gaps left where the curve is tighter than a straight section allows
- Inconsistent radius across a run when sections are bent individually
- Transitions between barrier types at the entry and exit of a banked section
- Finish quality visible on a facility where the installation is on show
Requirements
What Buyers in This Sector Need
- Sections bent to the actual radius of the alignment, convex or concave
- Consistent curvature across a whole run rather than section by section
- Terminal ends and transitions detailed for the direction of travel
- Galvanized finish that holds up outdoors over the life of the facility
- A supplier that can roll straight and curved sections from the same production run
Where It Goes
Typical Application Scenarios
- Banked curves on high-speed test loops
- Handling circuits with continuously varying radius
- Perimeter protection around test surfaces and run-off areas
- Transitions between straight barrier and curved sections
- Facility installations where finish and consistency are visible
Process
How We Deliver
- Provide the alignment radii and the section type the facility requires
- Curved sections are bent on the automatic bending machine to the radius given
- The passivation ratio is controlled so the galvanized surface resists corrosion
- Straight sections, posts and terminals are rolled and cut alongside the curved sections
- The complete run is bundled and shipped together
Track Record
Delivery Capability
- Supplied to the Mercedes-Benz automobile proving ground project
- Supplied to the Daimler automobile proving ground project
- Curved sections bent to any radius from 1.5 m to 50 m
- Convex and concave forms both produced
- Steel supplied by Tang Steel
Proving Grounds and Test Tracks Questions
Have you supplied proving ground projects before?
Yes. The Mercedes-Benz and Daimler automobile proving grounds are both listed among our project references.
How tight a curve can you produce?
Radii from 1.5 m to 50 m, in convex or concave form, to suit the alignment.
How do you keep the radius consistent along a run?
Sections are bent on an automatic bending machine, which is what holds the radius accurate rather than bending each section separately.
Can you supply straight and curved sections together?
Yes. Straight beam, curved sections, posts and terminals are produced here and can ship as one consignment.
What if the curvature is slight?
Where the curvature is not large it is straightforward to use the beam splice to connect the sections and install the post as support.
