W Beam
The W Beam is the primary component of highway guardrails. It's made of high-strength steel, shaped like a "W," and is designed to absorb and deflect the energy of an impact, protecting vehicles and passengers. The beam is typically hot-dip galvanized to resist corrosion and ensure longevity in outdoor environments.
Key Features:
Corrosion Resistance: Ideal for chemical plants, offshore platforms, and areas with high humidity.
Lightweight: Easier to transport and install compared to metal trays.
High Strength: Offers superior mechanical strength and load-bearing capacity.
Electrical Insulation: Non-conductive, making it safe for electrical installations.
Low Maintenance: Requires minimal upkeep, reducing lifecycle costs, Fire Retardant: Often treated with fire-retardant materials for added safety.
Post
The post is the vertical support structure for the W Beam. Posts are anchored into the ground and hold the W Beam at the correct height and alignment. They are usually made of steel or timber and are also galvanized for durability. Posts are essential for providing the structural stability of the guardrail system.

Spacer
The spacer separates the W Beam from the post and maintains a consistent distance between them. This gap ensures the guardrail can deflect properly during an impact, reducing the severity of collisions. Spacers are also hot-dip galvanized and designed to withstand harsh weather conditions.
