What is the Weight of Mild Steel and How is it Calculated?

The weight of mild steel is defined as the primary metric for determining the quantity of material required in construction projects, calculated precisely based on approved engineering dimensions.

For the mild steel offered by Matkal (30 mm thickness, 6 mm width, 6 meters length), the approximate weight ranges around 10.8 kg per piece, with a minor margin of error depending on the precise steel thickness. In construction projects within the Kingdom, it is always recommended to add 5% of the total weight as a reserve to ensure material availability during welding and cutting operations.

The physical density of steel varies by type; Grooved steel is characterized by a slightly higher weight due to the grooves that enhance grip strength, while Galvanized steel adds a protective layer that slightly alters its total weight compared to the standard type.

Purchasing Guide: How to Choose the Right Dimensions for Your Project?

Choosing the thickness of mild steel depends entirely on the expected load on the structure. Under the harsh conditions in Saudi Arabia, with high temperatures and coastal humidity in Jeddah, infrastructure engineers recommend using thicknesses of at least 25 mm for heavy loads.

From the Matkal store, we offer you a variety of options covering the needs of the Saudi market for 2026:

• Common Thicknesses: 6 mm, 10 mm, 20 mm, and 30 mm.
• Standard Dimensions: The approved length is 6 meters, while the width ranges from 6 mm to 40 mm according to demand.
• Surface Treatment: Choose between standard steel (for dry indoor projects), grooved steel (for outdoor projects exposed to wear), and galvanized steel (for marine environments and sandy areas).

Ensure that all Matkal steel prices mentioned include the 15% Value Added Tax (VAT) to guarantee financial transparency in your budget.
