    Main Application

     have a wide variety of applications, including:

    1. Security
    Metal barriers deliver robust physical protection for properties and effectively block unauthorized access to restricted zones. They are widely deployed in high-security sites including airports, government establishments, and military facilities.

    2. Vehicle Control
    Metal barrier systems including bollards, guardrails, and access gates help standardize vehicle flow and reduce collision risks. These solutions are extensively applied in parking lots, toll stations, and construction zones.

    Process of production

    The process of  involves several steps. Here is an overview of the general process:

    1. Raw Material

    High-strength Steel Coils (Q235B/Q355B).

    De-coiling and leveling to ensure flatness.

    2. Precision Punching

    CNC Automated Punching for bolt holes and slots.

    Ensures 100% alignment during site installation.

    3. Cold Roll Forming

    Steel passes through multi-stage rollers to form the "W" profile.

    This shape provides the mechanical strength for impact absorption.

    4. Cutting

    Hydraulic cutting to standard lengths (e.g., 4.32m or 3.81m).

    5. Surface Treatment (Protection)

    Hot-Dipped Galvanizing: Submerged in 450°C molten zinc for superior anti-corrosion.

    Optional Coating: Electrostatic powder coating (Green/Blue/White) for extra durability.

    6. Inspection & Loading

    Testing zinc thickness (min. 79μm) and mechanical properties.

    Bundling for international sea freight.

    Overall, the process of manufacturing a metal barrier is a complex process involving many different steps that requires skilled workers with specialized knowledge and equipment.

    Packing and Transportation

    Packaging is generally naked, steel wire binding, very strong.

    If you have special requirements, you can use rust proof packaging, and more beautiful.

    packaging

    Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)

    FAQ

     

    Q1: What is the standard length of a W-Beam guardrail?

    A: The standard effective length is typically 3.81m (12.5 ft) or 4.32m. However, custom lengths can be manufactured to match specific post spacing requirements.

    Q2: What is the difference between Class A and Class B guardrails?

    A: This refers to the steel thickness according to AASHTO M180:

    Class A: Base metal nominal thickness of 2.67mm (12 Gauge).

    Class B: Base metal nominal thickness of 3.43mm (10 Gauge).

    Q3: How long does the galvanizing last?

    A: Hot-dipped galvanizing (with a standard 550g/m² or 79μm coating) typically provides a service life of 20–50 years, depending on the corrosivity of the environment (coastal vs. inland).

    Q4: Can W-Beam guardrails be used on curves?

    A: Yes. For curves with a radius of less than 45 meters, the guardrails must be shop-curved (pre-bent in the factory) to ensure a precise fit and structural integrity.

    Q5: What are the standard post types used for installation?

    A: The most common are C-Posts, U-Posts, Sigma Posts, and H-Posts. The choice depends on the soil conditions and the specific highway safety standard of the region.

    Q6: Do I need a spacer (blockout) between the post and the rail?

    A: Yes. Spacers reduce the "wheel snagging" effect during a collision, preventing the vehicle's tires from hitting the posts, which helps maintain the vehicle's stability.

    Q7: How are the rails connected?

    A: They are overlapped in the direction of traffic flow and secured using 8 to 12 sets of M16 high-strength splice bolts.
