Open Box Beam Made to Your Specification
Open box beam guardrail is a continuous steel barrier with a rectangular cross-section, designed for high-impact resistance and long-term durability in roadside and median applications. It is commonly specified by road authorities in EU countries, where it is commonly specified for highway and urban infrastructure projects. The beam is hot-dip galvanized to 550 g/m2 and supplied in standard 4800 mm sections, with wall thicknesses rolled to customer specification. Production is carried out at Shandong Hongda Industry Co., Ltd using steel from Tang Steel, with full process control in-house.
Procurement Risk
Problems This Category Solves
- Barrier that fails inspection due to insufficient zinc coating on the galvanized surface
- Inconsistent steel grade across a shipment leading to variable crash performance
- Section mismatch at splices when the beam does not align with existing barrier runs
- Corrosion at cut edges or drilled points reducing service life in harsh environments
- Installation requiring on-site welding or drilling, increasing project time and safety risk
Buyers
Who It Is For
- Road authority contractors specifying EU road safety standards
- Highway construction companies sourcing barrier by the container for large-scale projects
- Civil infrastructure importers stocking barrier systems for regional distribution
- Road safety product distributors sourcing from a factory with in-house galvanizing and inspection
Why Hongda
Core Advantages
- Hot-dip galvanized to 550 g/m2
- Rolled from Q235B or Q345 steel supplied by Tang Steel, ensuring consistent mechanical properties
- Standard section length of 4800 mm
- No site welding required—sections bolt together using standard fittings and spacers
- Damaged sections can be replaced individually without replacing the entire run
Where It Goes
Application Scenarios
- Highway median separation in EU countries where box beam is the standard barrier type
- Urban roadways with high traffic volume requiring durable, low-maintenance crash protection
- Rural road edges protecting embankments, drainage channels, and roadside hazards
- Approaches to bridges and culverts where impact resistance and structural integrity are critical
- Roadside installations where long-term corrosion resistance is required without regular maintenance
Open Box Beam Questions Buyers Ask
What standard is your open box beam made to?
The beam is manufactured to meet the requirements of EU road safety specifications. The exact standard is confirmed per order based on the project's tender documents.
What steel grade and thickness do you supply?
Standard is Q235B (equivalent to S235JR) or Q345 (S355JR / ASTM A529M 1994), at 5.00 mm wall thickness. Other thicknesses are rolled to customer specification.
How thick is the galvanizing?
Zinc coating is 550 g/m2, measured at approximately 80 microns. Galvanizing is performed in-house to ensure consistent coating weight.
What are the section dimensions?
Standard section length is 4800 mm. The cross-section depth and width are designed to match EU installation standards. Custom dimensions are available upon request.
Can you supply posts and terminals with the beam?
Yes. Posts, spacers, terminal ends, bolts, nuts, and caps are produced in the same facility, so a complete barrier system can be supplied from one production run.
What is your minimum order and lead time?
Both are confirmed per order based on quantity and specification. Please send your drawing or tender extract to [email protected] for a quotation.
Do you export in full containers?
Yes. Box beam has been exported in around 100 containers per year to EU countries since 2010, primarily in full container loads.
