Smart & Steadfast: Why Steel Is Used In Car Manufacturing

A range of materials goes into automotive manufacturing, including plastic, aluminium and glass. But the primary material used in modern cars is steel, where the chassis and body are generally made from this durable metal alloy.

Steel as a known material has been produced since antiquity but did not begin to replace iron as a key component for construction until steel production began to become more efficient in the 19th century.

The first steel-bodied car was built in 1914, and its successful design became the template for automotive manufacturing in the decades that followed. Steel has now become a staple of the automotive industry for a variety of reasons. Read on to discover why steel is the foundational material in car manufacturing.

Strong Chemical Makeup

Steel is a metal alloy made up of iron and carbon. This means that it has an ideal atomic composition for construction. Steel atoms are differently sized, which disrupts the atomic layers. This means a great force is needed to make these layers slide, meaning that steel is incredibly strong and durable.

It has a high strength-to-weight ratio, where its lightweight qualities help to produce more fuel-efficient cars. Steel is also resistant to corrosion, meaning it creates long-lasting and reliable products.


Safety is a top priority when it comes to car and automotive manufacturing. Steel is the perfect material for designing crash resistant structures that excel at absorbing the impact of a collision.

A steel chassis is designed to collapse on impact. It also becomes harder and stronger when crushed, meaning it absorbs more energy from the crash in order to limit impact and protect the occupants of the vehicle.

Environmental Factors

Steel production has become more environmentally friendly in recent years, focusing on managing emissions and waste products. Steel produces less harmful emissions when produced compared to other materials, and only releases carbon dioxide, which can be managed with new and innovative eco-technologies.

Steel is also recyclable, and can be recycled infinitely back to its original structure. This helps to manage the sustainability of steel vehicles, whilst reusing and repurposing materials to save money and reduce waste.
