What is the difference between raw steel and galvanized steel?

Raw steel and galvanized steel are two common metal materials used in industry and construction. They have obvious differences in materials, properties and applications. This article will delve into the characteristics, differences and application scenarios of raw steel and galvanized steel.

First, let us understand the basic concepts of raw steel and galvanized steel. Raw steel, also known as ordinary steel or black steel, refers to ordinary steel without any surface treatment, and its main components are iron and carbon. Raw steel has good strength and plasticity, but is easily affected by oxidation, corrosion, etc., leading to surface rust. Galvanized steel is a layer of zinc coated on the surface of the original steel to improve its corrosion resistance and weather resistance.

Secondly, there are obvious differences in materials and properties between raw steel and galvanized steel. Raw steel is mainly composed of iron and carbon and has certain strength and toughness, but its surface is prone to rust and requires surface treatment to improve corrosion resistance. Galvanized steel is coated with a layer of zinc on the surface of the original steel, which effectively prevents oxidation and corrosion on the steel surface. It has better corrosion resistance and weather resistance, and is suitable for harsher environmental conditions.

In addition, raw steel and galvanized steel also have different application fields. Raw steel is commonly used in construction, manufacturing and furniture industries to make structural parts, pipes, mechanical parts, etc. Due to its excellent corrosion resistance, galvanized steel is often used in outdoor construction, marine engineering, automobile manufacturing and other fields that require high weather resistance, such as manufacturing roofs, walls, guardrails, etc.

To sum up, although raw steel and galvanized steel are both common metal materials, there are obvious differences in materials, properties and applications. Raw steel is mainly composed of iron and carbon, and is susceptible to oxidation, corrosion, etc., and requires surface treatment; while galvanized steel is coated with a layer of zinc on the surface of the raw steel, which has better corrosion resistance and weather resistance, and is suitable for more for harsh environmental conditions. According to different needs and application scenarios, selecting appropriate materials can better meet engineering and product requirements and ensure their performance and service life
