Sheet Weight Table and Its Calculation Formula Before Cargo Delivery

Suppose a customer asks how much a ۲ by ۱ متر sheet with a thickness of ۵ میلی‌متر weighs. Instead of guessing, simply perform a basic multiplication: ۲ × ۱ × ۵ × ۷.۸۵ equals ۷۸.۵ کیلوگرم. Unlike rebar and I-beams, whose weight is tied to the factory table, sheet weight can be calculated directly and accurately from its dimensions, and this provides you with a powerful tool for cargo control.

The Golden Formula for Sheet Weight

The weight of each steel sheet equals its length (متر) multiplied by its width (متر), multiplied by its thickness (میلی‌متر), multiplied by the constant ۷.۸۵. This number is the density of steel in grams per cubic centimeter and is the same for all types of sheet, from black and oiled to galvanized. This single relationship is the basis of the entire sheet weight table.

Unlike rebar, sheet weight can be calculated directly from its dimensions; this makes cargo control easier.

Weight Table for Several Common Dimensions

How to Use This Table for Cargo Control

Before settling the payment, multiply the number of sheets of each dimension by the theoretical weight of that dimension and compare the total with the weighbridge weight. A small difference due to permissible tolerance is natural, but if the actual weight is several percent and consistently lower than the theoretical figure, you are probably dealing with under-thickness sheets.

This table does not replace the factory catalog, but for a trader who wants to quote a price quickly or check the cargo weight on the spot, it is faster and more accurate than any ready-made table, because it requires only three simple numbers.

A Brief Reminder

Always use ۷.۸۵ for carbon steel sheet; for stainless steel sheet, the density is approximately ۸.۰.
