1. Maintaining Distance: Spacers are strategically positioned between the W-shaped beams (W-Beams) of a crash barrier. Their primary function is to maintain the proper distance and alignment between these beams, ensuring that they are evenly spaced and provide effective coverage along the road or bridge.
2. Enhancing Efficiency: By ensuring consistent spacing between W-Beams, spacers contribute to the overall efficiency of the crash barrier system. This uniformity helps the barrier absorb and redirect impact energy during accidents more effectively.
3. Preventing Overlapping: Spacers prevent the W-Beams from overlapping, which could reduce the barrier’s effectiveness in absorbing and deflecting the force of a collision.
4. Support: Spacers provide additional support to the W-Beams, helping to keep them in place and maintain their structural integrity.
5. Versatility: Spacers can be used on both ground-level roads and elevated structures like bridges, offering flexibility in crash barrier deployment.
1. Structural Strength: Spacers are constructed using channel sections of 75*150*75*5mm and 5mm thick HR sheets. This robust construction ensures that they can withstand the forces generated during accidents without deforming or collapsing.
2. High-Quality Steel: They are typically made from high-grade steel, such as Fe 410/Fe 360, which conforms to standards like IS 5986 or IS 10748. This choice of material guarantees durability and longevity, even in harsh outdoor environments.
3. Corrosion Resistance: Spacers are hot-dip galvanized to 550 gms/sq.m, conforming to industry standards like MORT&H and IS. This galvanization provides excellent resistance to rust and corrosion, ensuring a long service life.
4. Precise Spacing: The design of spacers ensures precise and consistent spacing between W-Beams, which is crucial for the barrier’s proper function.
5. Ease of Installation: Spacers are designed for straightforward installation, allowing for efficient deployment as part of the crash barrier system.
6. Cost-Effective: They offer a cost-effective solution for improving road safety by enhancing the performance of crash barriers.
7. Proven Effectiveness: Spacers play a vital role in ensuring that crash barriers perform effectively in reducing the severity of accidents and protecting road users.
