Benefits of Brushing Bitumen on the Bottom of Steel Poles

Brushing bitumen on the bottom of steel poles provides several crucial advantages, making it a widely adopted practice. Firstly, bitumen acts as an outstanding waterproofing agent. The bottom part of steel poles is often exposed to ground moisture, rainwater, and even groundwater seepage. Bitumen forms a dense, impermeable layer that effectively blocks water from reaching the steel surface, preventing rust and corrosion caused by prolonged moisture contact. This significantly extends the lifespan of steel poles, especially in areas with high humidity or frequent rainfall.

Secondly, bitumen offers excellent chemical resistance. It shields the steel from harmful substances in the soil, such as acidic or alkaline compounds, which can gradually degrade the metal. By creating a protective barrier, bitumen helps maintain the structural integrity of the poles over time. Moreover, bitumen has good adhesion properties, firmly bonding with the steel surface and remaining intact even under varying temperature conditions and mechanical stress. This ensures long - term protection without easily peeling off.

In addition, applying bitumen is relatively cost - effective and easy to implement. It serves as a simple yet efficient preventive measure, reducing the need for frequent and costly repairs or replacements of steel poles. Overall, brushing bitumen on the bottom of steel poles is a practical and beneficial approach for enhancing durability and reducing maintenance costs.
