What is Red Iron Steel?
Red iron steel, or structural steel, is used for construction purposes because it is tough and long-lasting. This type of steel is covered with red oxide, which protects it from rust and corrosion. Besides construction, red oxide primer is also used for automotive parts since it can easily be painted over. It is often used for frameworks in buildings, warehouses, and other large structures as it is cheaper than alternatives.
Understanding Red Iron and its Properties
Red iron is highly valued in construction due to its strength and durability. Below are five key reasons why red iron should be considered for structural use.
- Resistance to Corrosion
Using red oxide primer on the surface enhances the material’s potential for enduring rust and corrosion, even in extreme environmental conditions.
- High Strength
Red iron’s strength allows it to shoulder considerable loads while offering stability to support expansive structures.
- Cost-effectiveness
Builders will find red iron to be inexpensive, as it combines low cost with durability over time, a rare combination among building materials.
- Ease of Assembly
Red iron pieces can be pre-engineered, which saves on assembly and increases efficiency, reducing construction time and labor costs.
- Fire Resistance
The material’s high fire endurance achieves increased structural safety and compliance with building safety codes.
The Role of Iron Oxide Coating
Red iron steels are more appealing because of iron oxide coatings. Iron oxide coatings can shield red iron from moisture and oxygen without aesthetics. Studies suggest that harsh conditions do not impact the lifespan of iron oxide-coated red steel. Instead, it can increase its lifespan by 60%.
Moreover, developments in coating technology have also enhanced performance. Newer modern iron oxide coatings have better adhesion; thus, they are more readily bonded to the metal surface. Because of this, maintenance is less frequent, and structural repairs are more cost-effective in the long term. Research indicates that structures with iron oxide-coated red iron require significantly less maintenance and incur about 30% less maintenance cost over 20 years.
In addition, this iron oxide coating is found to be more environmentally friendly than others, because many are water-based which reduces the emission of VOCs into the atmosphere, thus contributing towards a more sustainable option for large construction projects.
