Q235 Galvanized or Powder Coating Steel Highway Guardrail Systems for Road Safety

Product Introduction:

Highway guard rail are mainly used for separating and defining aisle ways, large work areas, walkways and inside loading docks. Guard rail provides a visual and physical barrier between traffic and work areas. It is of protection against accidents due to lift trucks or other mobile equipment in dock areas, aisles, around special equipment, or offices. Using of galvanized steel guard rails reduces costly damage to equipment and inventory. If any need, it is easy to expand or move modular system. It is suitable for indoor or outdoor use as well.

Highway guardrail is also for highway safety. Metal guard rail is fixed on the side of the roads or middle of the road, especially on curves and slopes for preventing vehicles from riding out from roads. The w beam barriers are of excellent anti-corrosion and tensile strength. So that, it is good to minimize the damage to driver and pedestrian.

It’s often need to remove guardrail temporarily for unobstructed maintenance or other access to an area. Layout flexibility and the ability to relocate barriers at minimal cost is an important factor.

Highway Guard Rail Parameters

Sunrise safety highway metal guard rails provide a substantial highly visual physical barrier that addressed all of these issues.

Four types and two classes of steel guard rail is provided follows:

Guard Rails Materials:

• A 307, Standard Specification for Carbon Steel Bolts and Studs, 60000 psi Tensile Strength.
• A 653 / A 653M, Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process.
• F 376, Standard Specification for Carbon and Alloy Steel Externally Threaded Metric Fasteners.

Road Guard Rail Properties:

• W beam metal guardrail and transition sections:
  Yield point, minimum 345 MPa (50000 psi).
  Tensile strength, minimum 483 MPa (70000 psi).
  Elongation in 50 mm (2 in.), minimum 12 %.
• End and buffer sections:
  Yield point, minimum 227 MPa (33000 psi).
  Tensile strength, minimum 310 MPa (45000 psi).

Road Guard Rail Coating Requirements

Type I and Type II beams:
The beams may be galvanized before after fabrication.
The mass of coating shall conform to the requirements in the following table for the types specified. The mass of coating is the total amount of galvanizing on both sides of a sheet or beam, expressed as g/m2 (& oz/ft2) of sheet.

We strictly supply road safety W-Beam highway Guard rail to rigorous local and international standards (JT/T 281-2007, AASHTO-M180, RAL RG620 etc.) or as per clients’ w beam dimensions. With many undergoing crash testing in accordance with international standards such as MASH, NCHRP Report 350.

Highway Guard Rail Features

1. Low costs of raw materials, long service life. special w beam dimensions acceptable.
2. High steel sheets are all processed through antiseptic treatment, which makes guardrail better properties.
3. Excellent impact resistance, high safety performance.
4. Anti-corrosion, anti-aging, elegant shape, be fast and easy to install.
5. Thrie beam barrier Guardrails can be tailored to any application, and are available to meet all design requirements and standards

Applications

1. Highway guard rail can be used in parking lots,single and multi-lane highways, bridges, and bridge approaches.
2. Mainly used for the isolation and protection between highway and lane.
3. Applied to industry, agriculture, municipal administration, transportation and other industries to act as fence, decoration, and safeguard.
4. Can be used in curves and slops, and the damage is easy to replace.
