Introduction
MS Square Pipe (HSH) is a type of steel pipe, mostly used in the construction and manufacturing industries. Most MS square pipes are hollow, which can reduce weight while taking into account structural strength. This can be better used in frames, columns, machine brackets, etc.
For those who are new to the pipeline industry, to understand MS square pipes, you need to understand materials, weight calculations, dimensions and wall thickness. You also need to know the weight and price of square pipes per meter under normal circumstances. This is helpful for quoting customers or calculating costs.
What Is an MS Square Hollow Section?
MS square pipes are steel pipes with a square shape, a hollow middle, and a material of low-carbon steel. Usually the standard length of the steel pipe is 6 meters, of course, the factory can also produce according to customer requirements.
Common applications of square pipes:
Structural frames and supports
Frames for greenhouses and sheds
Fences and railings
Furniture frames
Its characteristics are: uniform shape and no burrs. Easy to cut and weld and install.
How Is the Weight of MS Square Pipes Calculated?
The weight of a square pipe depends mainly on the following factors:
Side length (A) is the cross-sectional width of the square pipe (unit: mm)
Wall thickness (T) is mostly in mm
Length: 6 meters in general, customizable
Steel density: about 7850 kg/m3
Basic Formula
Weight (kg/m) = [(A² – (A – 2T)²) × 7850] × 10⁻⁶
Sample Weight Chart (in kg/m)
| Size (mm × mm) | Thickness (mm) | Weight per meter (kg/m) |
|---|---|---|
| 20 × 20 | 1.6 | 0.91 |
| 25 × 25 | 2.0 | 1.50 |
| 30 × 30 | 2.5 | 2.25 |
| 40 × 40 | 3.0 | 3.45 |
| 50 × 50 | 3.2 | 4.60 |
| 60 × 60 | 4.0 | 6.60 |
| 75 × 75 | 5.0 | 10.75 |
| 100 × 100 | 6.0 | 15.70 |
Note: The above values are for reference only. The specific data may have tolerances due to different production processes, and the range is mostly around 2.
Why the Weight Chart Matters
1. Structural design
Engineers and builders need to choose the appropriate size and wall thickness according to the actual application to support their corresponding applications.
2. Material cost
Depending on the production process and raw materials, the cost of the steel pipe is also different. With the above data, the price of the steel pipe used is calculated based on the price per meter.
3. Transportation and moving
Accurately calculating its weight helps to choose the right handling tools.
4. Project budget
The price can be roughly calculated based on its weight and length, so that the contractor can estimate the price in advance. Convenient for procurement.
Tips for Beginners
Square tubes can withstand different pressures with different wall thicknesses. The thicker the wall thickness, the greater the pressure it can withstand, but the corresponding cost is also higher.
For some furniture frames, etc., lightweight square tubes can be selected.
The price should be calculated based on weight, number of meters, material and production process. If there is waste of scraps, the price should be adjusted accordingly.
Summary
MS square tubes are one of the preferred choices for many construction and industrial uses. Its structure is stable.
So how to calculate the price:
First, use the size and wall thickness to determine the weight.
Then use the weight per meter multiplied by the length to get the total weight.
Then determine the price based on the unit price.
Knowing the above, both sales and procurement have a certain understanding of MS square tubes, and can better choose the size and length they need.
