1. Understanding Different Types of Steel

Before purchasing, it’s essential to understand the differences between low galvanized steel, carbon steel, and stainless steel:

Low Galvanized Steel Sheet Rolls

- Coated with a thin layer of zinc to prevent rust.

- Ideal for outdoor applications, roofing, and automotive parts.

- Available in various thicknesses and finishes.

Carbon Steel

- Contains higher carbon content, making it strong but less corrosion-resistant.

- Used in construction, machinery, and industrial applications.

- Comes in low, medium, and high carbon variants.

Stainless Steel

- Contains chromium for corrosion resistance.

- Common in food processing, medical equipment, and marine environments.

- Grades include 304, 316, and 430, each with different properties.
