Rolled-Edge C-Shaped Support Profile
The C-Channel Guardrail Post is a main support component used in corrugated highway guardrail systems. It has an open C-shaped section with inward-rolled edges and can be connected to W-beam panels, spacer blocks, brackets, and fastening bolts.
The inward-rolled edge helps increase the stiffness of the section and reduces the possibility of twisting during transport, installation, and loading. Compared with some solid or heavier steel support sections, the C-shaped profile balances structural support with component weight. This can make bulk transportation and on-site handling more manageable.
The post can be used with mechanical driving, prepared foundations, or another installation method specified by the project. Its final application should follow the complete guardrail system drawing.
The product information lists two common size groups: 120 × 55 × 16 × 4.0 × 1800/1830 mm and 120 × 68 × 20 × 4.3 × 1830 mm.
Forming, Holes, and Galvanized Protection
The post can use a one-piece formed structure. Installation holes are produced through punching to match the guardrail beam, spacer block, or bracket.
Hot-dip galvanizing creates a zinc layer on the external surfaces and accessible internal surfaces. This helps protect the steel during long-term outdoor use.
The source information states that this type of post can be used in corresponding EN 1317 H1 or H2 guardrail systems. However, the containment level applies to the approved complete system rather than to one post alone. The beam type, post spacing, spacer blocks, fasteners, installation height, and approved system documents must all match.
Buyers should provide the complete section dimensions, wall thickness, post length, hole drawing, and galvanizing requirements. C-channel posts used in different projects may have different opening widths, rolled-edge dimensions, or hole positions and may not be directly interchangeable.
Controlled Production for Standard and Custom Sizes
The factory has forming, cutting, punching, and hot-dip galvanizing capabilities for guardrail post production. Before a non-standard order enters production, the technical team can review the section size, steel thickness, post length, hole diameter, hole spacing, and beam connection method.
A first piece can be produced and confirmed before mass production. The production process includes incoming material inspection, in-process checks, anti-corrosion process control, and final inspection.
Important inspection points include the formed dimensions, component straightness, hole positions, and zinc coating condition. Buyers may inspect the products during production or before shipment. Third-party inspection of dimensions, thickness, and coating can also be arranged.
Coordinated Supply and Export Packing
The C-Channel Guardrail Post can be purchased as part of a complete W-beam guardrail order or separately for road maintenance and replacement work.
Common sizes may support small orders depending on available stock. Custom sections, special hole arrangements, and private-label products are manufactured according to approved drawings.
For export, posts can be bundled and secured with steel straps. Waterproof materials and separators can be added to reduce surface damage. Bolts and small connecting parts are packed separately, while timber supports can be used inside the container. Large orders can also be delivered in stages according to the construction schedule.
