If the seller only tells you the price per kilogram, you still do not know how much each profile length will cost. For a proper purchase, you need to consider four figures together: dimensions, thickness, length, and the weight of the length. Light-weight profile is no exception to this rule.
Very simple summary: Light-weight profile, or furniture profile, is a thin-walled steel box section usually made from cold-rolled oiled sheet. Its low weight, clean surface, and good formability make it suitable for tables and chairs, shelves, decoration, and delicate industrial components; however, technical calculations are required for a load-bearing member.
What exactly is a light-weight profile?
On the production line, rollers form the cold sheet into a square or rectangle, and a welding machine joins the edges together. In the market, you may also hear this product referred to as «furniture profile» or «oiled box section». These names are common, but when placing an order, do not rely only on the name; the dimensions and thickness must be written on the pro forma invoice.
Market thicknesses are not the same for all factories. For example, Saba Profile has announced a range of ۰٫۷ to ۱٫۵ millimeters for a ۳۰×۵۰ light-weight box section. This is only one example of market production, not an ever-present rule. The inventory, base sheet, and tolerance of each factory may differ.

The difference between light-weight and heavy profiles in simple terms
| Subject | Light-weight profile | Heavy profile |
|---|---|---|
| Common sheet | Oiled or cold-rolled | Black or hot-rolled |
| Appearance | Usually smoother and cleaner | Usually rougher |
| Weight | Lower in similar dimensions | Higher in similar dimensions |
| Common application | Furniture, decoration, and delicate components | Heavier construction and industrial work |
| Buying note | The final selection must be based on the load, actual thickness, sheet quality, and type of connection. |
A common mistake is for the buyer to compare only the price per kilogram. A light-weight profile may be more expensive per kilogram, but because each meter weighs less, the final cost of the component may be lower.
For example:
At the time of review, the Ahantime furniture profile section had a product titled ۶۰×۶۰ furniture profile and box section. On ۱۴۰۵/۰۶/۰۹, the product page showed a price of ۱۶۰٬۰۰۰ tomans per kilogram and a delivery time of ۷۲ hours.
But an important point: On the same page, the thickness, condition, and length weight were listed as «unknown». Therefore, this figure alone is not enough to calculate the price of each length. Before ordering, ask these three questions: What is the exact thickness in millimeters? How many meters is each length? What is the actual weight of each length?
The above price relates to the latest page entry on ۱۴۰۵/۰۶/۰۹ and may have changed. For the latest figure, see the Ahantime furniture profile price table. If the specifications are still incomplete, ask the expert to record them on the pro forma invoice.
Where is light-weight profile useful?
- Furniture and decoration: Frames for tables, chairs, sofas, clothing racks, and store displays
- Shelves and light equipment: Frames and bases where low weight is important
- Home appliances and industrial components: Parts requiring dimensional accuracy and a clean surface
- Bending and plating: Components that need a neater appearance after production
For a column, beam, or any component whose failure could cause personal injury or financial damage, do not make a decision based on market guesses and experience. The type of steel, unsupported length, load, and connection shape must be calculated.
What is the difference between light-weight profile and furniture tube?
The sheet material and some applications of the two are similar, but the cross-sectional shape is different: furniture profile is usually square or rectangular, while furniture tube has a round cross-section. For bending, connection, or component design, one cannot be substituted for the other without examination.
How do you calculate the weight of light-weight profile?
For a square or rectangular box section, this formula provides a good estimate:
Length weight (kilograms) ≈ ۰٫۰۱۵۷ × thickness × (width + height − ۲ × thickness) × length
Enter the width, height, and thickness in millimeters and the length in meters. The resulting figure is theoretical; the corners of the box section and production tolerances cause the actual weight to differ slightly. For transactions, the scale weight or the factory’s official table is more important.
| Size and thickness | Length of section | Approximate theoretical weight |
|---|---|---|
| ۲۰×۲۰×۱ millimeters | ۶ meters | ۳٫۵۸ kilograms |
| ۲۰×۴۰×۱ millimeters | ۶ meters | ۵٫۴۷ kilograms |
| ۳۰×۵۰×۱ millimeters | ۶ meters | ۷٫۳۵ kilograms |
As a simple check, Markazeahan has announced the weight of a six-meter ۲۰×۴۰×۱ length as approximately ۵٫۶ kilograms; in other words, it is close to the theoretical figure of ۵٫۴۷. This small difference is natural, but investigate any major difference before delivery. For other dimensions, use the steel products weight calculator.
How do you choose the right profile?
First, determine the application. For a decorative display, appearance and weight are more important; for a machine base, load-bearing capacity and vibration matter more. Then determine the thickness, and only after that compare prices. If the seller does not state the weight of the length, you cannot calculate the price of each length correctly.
A short pre-purchase checklist
- Write the dimensions, thickness, length, and number of lengths on the pro forma invoice.
- Compare the theoretical weight with the announced weight and the scale weight.
- Check the surface for rust, waviness, scratches, and dents.
- The weld line should be uniform and should not have any obvious opening.
- For painting, plating, or bending, ask about the quality of the base sheet.
- Do not forget taxes, cutting, packaging, and shipping when comparing prices.
How was this article reviewed?
This guide was prepared by the Ahantime editorial team based on a direct review of the Ahantime catalog on ۱۴۰۵/۰۶/۱۰, the ۶۰×۶۰ product page, Saba Profile technical information, and Markazeahan’s light-weight product weight table. The weight table in this article was calculated using an approximate steel-density formula, and for final orders it must be checked against the factory sheet or scale.
Conclusion
Light-weight profile is a good choice for delicate and low-weight work, provided that you purchase it with complete specifications. Do not forget the four figures: dimensions, thickness, length, and the weight of the length. Then compare the price per kilogram. If any of this information is unclear, obtain it in writing before making payment.
Frequently Asked Questions
پروفیل سبک چیست؟
پروفیل سبک یا مبلی، قوطی فولادی کمضخامتی است که معمولاً از ورق روغنی نورد سرد ساخته میشود و برای قطعات سبک و ظریف کاربرد دارد.
آیا پروفیل سبک همان پروفیل مبلی است؟
در بازار ایران معمولاً بله؛ اما هنگام سفارش حتماً ابعاد، ضخامت، طول، وزن شاخه و کارخانه را دقیق مشخص کنید.
وزن پروفیل سبک چگونه محاسبه میشود؟
برای قوطی مستطیلی از رابطه تقریبی ۰٫۰۱۵۷ × ضخامت × (عرض + ارتفاع − ۲ ضخامت) × طول استفاده کنید. ابعاد و ضخامت میلیمتر و طول متر است.
چرا قیمت هر کیلو پروفیل سبک از پروفیل سنگین بیشتر است؟
ورق روغنی و تولید دقیقتر میتواند قیمت کیلویی را بالا ببرد؛ بااینحال وزن کمتر هر متر ممکن است هزینه نهایی شاخه را کاهش دهد.
