Steel Beam Weight Table and a Trick for Counting the Delivered Bundle

You have received a bundle of size ۲۰ steel beams containing ۱۸ pieces. The invoice says the total weight is ۴٬۸۴۰ کیلوگرم. Before signing the receipt, how can you determine in less than a minute whether this figure is reasonable? The answer lies in two simple numbers: the number of pieces and the weight of each piece according to the کارخانه table.

Steel Beams Are Also Traded by Weight, Like Rebar

Steel beam pricing is based on weight, not the number of pieces. The important difference compared with rebar is that each steel beam individually has considerable weight, so even a small error in counting or calculation quickly turns into a large figure.

Counting the number of pieces and multiplying by the table weight is faster than opening the entire bundle to weigh the pieces individually.

A Trick for Counting the Bundle Without Weighing Each Piece

Instead of opening each piece and weighing it separately, simply count the number of pieces in the bundle and multiply it by the table weight. For example, a standard size ۱۶ bundle usually contains ۲۶ pieces; ۲۶ multiplied by ۱۸۹.۶ کیلوگرم is approximately ۴٬۹۳۰ کیلوگرم. A size ۲۰ bundle with ۱۸ pieces comes to approximately ۴٬۸۴۰ کیلوگرم, and size ۲۴ with ۱۳ pieces comes to approximately ۴٬۷۹۰ کیلوگرم. All three figures fall within the usual کارخانه packaging range (approximately ۴.۵ to ۵ tons); if your invoice figure is noticeably outside this range, it is worth questioning.

Why This Method Is Better Than Weighing Each Piece Individually

• It is faster; you take the entire bundle to the weighbridge once, rather than weighing each piece separately.
• There is no need to open the bundle’s straps, so the bundle remains intact until settlement.
• It immediately reveals a large and unusual discrepancy, without additional equipment.

Why the Actual Weight Sometimes Differs Slightly from the Table

The table weight is a theoretical figure; in practice, the thickness of the flange and web varies slightly from one کارخانه to another, and this affects the final weight. ذوب‌آهن اصفهان is usually considered the market reference for this table because of its high rolling precision; other factories may be a few percent higher or lower. The point is that this difference should be small and fall within a reasonable range, not be a large one-sided reduction.

These few minutes of calculation are exactly what distinguishes a routine transaction from an unexpected loss; especially when steel beams are involved, each piece by itself is worth an amount equivalent to several rebar pieces.
