Renting steel formwork manufacturers: How much does the material of steel formwork affect the price?

1、 Comparison of Material Price Differences (Direct Cost Impact)
Material type price range (yuan/ton) price difference characteristics
Ordinary carbon steel (Q235) 3000-4000 is the preferred basic building material with the lowest cost of 69
Low alloy steel (Q345) 4000-5000 has a 37% increase in strength and a 3-8% increase in unit price, but with a 15-20% reduction in usage
Stainless steel (304) 18000 unit price is 4-6 times that of carbon steel, with strong corrosion resistance of 12
Note: The premium for customized high-strength steel (such as Q390) can reach 20-30%.
2、 Indirect costs caused by material properties
Correlation between strength and dosage
The Q345 steel formwork has a yield strength of 345MPa, and the beam column section can be reduced by 15% -20% compared to Q235, reducing the overall procurement cost.
Process adaptability
Stainless steel requires laser cutting technology, with processing costs 25-40% higher than carbon steel
Welding high-strength steel requires low hydrogen welding materials, which increases costs by 8-12%
3、 Market linkage effect
Price Transmission of Alloy Elements
For every 10000 yuan/ton increase in nickel prices, the cost of 304 stainless steel increases by 6% simultaneously.
The impact of policy regulation
During the period of environmental production restrictions, the supply of low-alloy steel is tightening, and regional premiums may reach 10-15%.
4、 Typical scenario cost comparison
Taking the standard box girder formwork for bridge engineering as an example (with a usage of 10 tons):
Q235 steel formwork: total cost ≈ 38000 yuan (including 5% process surcharge)
Q345 steel formwork: total cost ≈ 42000 yuan (reduced usage after strength improvement, comprehensive cost only increases by 10%)
304 stainless steel template: total cost ≈ 180000 yuan (additional calculation is required for full lifecycle anti-corrosion cost savings)
5、 Procurement optimization suggestions
Ordinary buildings: Q235 is preferred as the optimal solution for cost sensitive scenarios
Heavy load structure: Q345 is used to achieve a balance between strength and cost
Corrosion environment: The full cycle cost of stainless steel formwork may be lower than the maintenance cost of carbon steel
Note: The main contract price for rebar futures in May 2025 is 4850 yuan/ton, an increase of 12% from the beginning of the year. It is recommended to track the steel index in real time and adjust the procurement strategy.
