To calculate the price of a crowd control barrier, we begin by determining its total weight. Using this weight, we then break down the costs by calculating the price for each specific type of steel tube utilized in the barrier’s construction. By multiplying the weight of each steel tube by its corresponding price, we can establish the total raw material cost.
After determining the material cost, we factor in additional elements such as manufacturing, labor, galvanization (if necessary), and transportation costs. We then add these components to the material cost to calculate the final price of the crowd control barrier.
This methodical approach ensures precise pricing based on the weight of materials and the inclusion of production-related costs. We will use the following crowd control barrier specifications as a reference for calculating its price:

Total Length | 2170mm |
Total Height | 1090mm |
Top Frame Tube Diameter | OD38 x 1.5mm |
Vertical Tube Diameter | OD16 x 1.2mm |
Vertical Tube Spacing | 100mm |
Base Plate Dimensions | 500 x 50 x 10mm |
Handle Height | 570mm |
Top Space (Gap) | 180mm |
Bottom Space (Gap) | 100mm |
Vertical Tube Length | 904mm |
Arc Radius | 166mm |
When calculating the weight of a crowd control barrier, we employ a segmented approach to analyze each component of the barrier. Based on the provided image and specifications, we can break down the barrier into the following parts for easier calculation:
By calculating the weight of each part separately, we can accurately determine the total weight of the crowd control barrier, which will be essential for further cost calculations.
First, we need to calculate the weight of one meter of OD38mm x 1.5mm galvanized steel tube. The calculation process is as follows:
To calculate the weight of a 38mm x 1.5mm x 1000mm steel tube, you can follow these steps:
By following this method, we calculated the weight to be approximately 1.35 kg for a 1-meter section of a 38mm x 1.5mm steel tube.
Due to the base plate’s thickness of 10 mm, the total height of the barriers will be 1,080 mm and female and male locking equal to 170mm
Parameter | Calculation | Result |
---|---|---|
Total Horizontal Width (W_c) | 2000 mm – 2 × 19 mm | 1962 mm |
Total Vertical Height (H_c) | 1080 mm – 19 mm | 1061 mm |
Horizontal Straight Length (L_straight) | 1962 mm – 2 × 166 mm | 1630 mm |
Arc Length per Bend (S_bend) | π × 166 mm / 2 | ~260.8 mm |
Total Arc Length (S_total bend) | 2 × 260.8 mm | 521.6 mm |
Vertical Straight Length (L_vertical) | 1061 mm – 166 mm | 895 mm |
Total Vertical Length (L_total vertical) | 2 × 895 mm | 1790 mm |
Total Pipe Length (L_total) | 1790 mm + 521.6 mm + 1630 mm | 3941.6 mm |
Total Pipe Length in Meters | 3941.6 mm ÷ 1000 | 3.94 meters |
Total weight : 3.94 meters x 1.35kg =5.319kg
The total length of the crowd control barriers is 2170mm, including the male and female locking mechanism, which together measure 170mm. After deducting the 170mm for the locking mechanism, the overall dimension is reduced to 2000mm. The frame consists of two tubes, each 38mm in diameter, resulting in a bottom rail length of 2000mm – 76mm = 1924mm.
The total weight is calculated as 1.924m × 1.35kg, which equals 2.6kg.

With a total barrier width of 2,000 mm, the two outer pipes take up 76 mm. Adding 16 vertical pipes uses an additional 256 mm. The spacing between these pipes, at 97.18 mm each, totals approximately 1,457.7 mm. Together, all components occupy about 1,789.7 mm, leaving 210.3 mm for side margins. This configuration ensures that the barrier is balanced and structurally sound with 16 vertical pipes.
So total need 16 x 914mm x 0.44kg/m =6.43kg

The crowd control barrier is equipped with two base plates, each measuring 50mm x 10mm x 100mm. The total weight of the two base plates is 3.92kg, as each plate weighs 1.96kg.
The crowd control barrier also includes male and female hooks, which weigh 1kg in total. The price for these hooks is 1 Australian dollar. These hooks are designed for secure connection between barriers, ensuring stability during use. They are durable and easy to install, providing a reliable solution for maintaining orderly crowd control in various settings.
The price of Powder coating ranges from 0.3 to 0.8 Australian dollars per kilogram, depending on the type of polyester used. For example, standard export-grade polyester costs around 0.3 AUD per kg, while AkzoNobel powder, known for its excellent anti-aging and UV resistance properties, can reach 0.8 AUD or higher. For this calculation, we will use a mid-range price of 0.55 AUD per kg. The cost of hot-dip galvanizing (ranging from 300 grams to 600 grams per square meter) varies between 0.5 and 1.0 AUD per kg, meeting international shipping standards. However, in this case, we will focus solely on calculating the price of powder-coated crowd control barriers.It is worth mentioning that after polyester powder coating, the total weight of each crowd control barrier will increase by 2.5% to 3.5%.
Since China is a major steel producer with significant overcapacity, the price of steel in China is generally much lower than the local price in Australia. For a rough estimate, you can refer to this link: https://www.sunsirs.com/uk/sectors-13.html.
For example, if today’s steel price is 1,000 Australian dollars per ton, and the total weight of our barrier is 19.329 kg, with polyester coating costs at 0.55 AUD per kg, the final price calculation would be:
19.329 kg x (1.00 AUD + 0.55 AUD) = 29.96 AUD.
This price includes both the cost of raw materials and surface treatment.
The total cost of a crowd control barrier, delivered to an Australian port, is broken down as follows:
Adding these components together, the total price per crowd control barrier, landed at an Australian port, is 44.96 AUD. This includes the cost of raw materials, welding, freight, and profit margin.
In conclusion, the pricing of crowd control barriers is a comprehensive process that meticulously accounts for each component’s weight and associated costs. By segmenting the barrier into its constituent parts—such as the round top section, bottom rails, upright tubes, base plates, and connection hooks—we ensure an accurate and transparent calculation of raw material expenses. The integration of factors like steel pricing, polyester powder coating, welding, and freight costs further refines the final price, resulting in a landed cost that is both competitive and reflective of quality.
Our example illustrates a total barrier cost of 44.96 AUD, which encompasses materials, surface treatment, welding, freight, and a modest profit margin. This methodical approach not only highlights the cost-efficiency achieved through China’s steel production capabilities but also underscores the importance of factors such as currency fluctuations and transportation logistics in determining the overall pricing.
