Understanding Hot-Dipped Galvanized Guardrail Systems

According to recent online resources, hot-dipped galvanized W-beam guardrails are vital for highway safety, especially when you need robust, long-lasting barriers. These systems consist of beams (including both W-beams and thrie beams), along with galvanized posts and terminal ends, designed to ensure effective anti-collision measures with varying safety grades ranging from A to SS.

Common Specifications from SciSe Exports:
- Two-wave profile: 310mm x 85mm x 3/4mm
- Three-wave profile: 506mm x 85mm x 3/4mm
- Matching posts for two-wave: 114/140mm x 4.5mm
- Upright posts for three-wave: 130mm x 6mm, 140mm x 4.5mm
- Anti-collision grade: A/B/SA/SB/SS

Manufacturing and Quality Standards: Adheres to JT/T281 for China, AASHTO M-180 for the USA, and RAL-RG620 for Germany, among other international guidelines.

Hot-dipped galvanized steel guardrails serve as effective safety barriers for highways, expressways, and bridges. The thick zinc coating offers impressive corrosion and rust resistance, providing a long service life that justifies the costs associated with high-quality galvanization.

W-Beam Guardrail for Highways

Gregory Highway's W-Beam guardrail meets standard lengths of AASHTO 12' 6" or 25' 0". In addition, custom lengths and post-hole spacing are available on request. The guardrail is constructed using either 10-gauge or 12-gauge steel and is offered in four finish types, including pre-curved shapes.

Galvanizing Process for W-Beam Steel

Prime steel is utilized, matching quality standards for physical properties and chemistry. A meticulous cleaning procedure preps the steel for galvanizing, which is accomplished on a continuous galvanizing line. The process also includes piercing steel for specifications and rolling it into the distinct W-Beam profile.

Compliance with AASHTO Specifications

Manufactured under AASHTO standards, Gregory's W-Beam guardrail adheres to M-180 Classes A or B, with various finish types. Each guardrail piece is distinctly stamped with brand registration throughout its length.
