Roof girder price – comprehensive calculation of hall structures
Roof girder price is shaped by the span of the structure, the type of section, the class of concrete and the degree of prestressing of the element. Valuation includes the cost of design, production of prefabricated product, specialized transport and installation by crane. Roof girders price significantly depends on the size of the order – with large halls possible quantity discounts of up to 15-20%.
Cost structure of roof girders
The main component affecting the price of roof girders is the cost of production, which accounts for 65-75% of the value. The unit price for a running meter of a girder with a span of 18 m is 2500-3500 PLN. Prefabricated roof girders price increases non-linearly with the span – a 24 m element costs 4000-7500 PLN/mb net.
Specialized transportation accounts for 10-15% of the total cost. The price of transporting reinforced concrete roof girders with low-loader trailers is 15-25 PLN/km for standard lengths. Pilotage and permits for oversized loads are an additional 2000-5000 PLN.
Price list 2024 for roof girders
In 2024, a stabilization of prefabricated prestressed concrete prices is observed after previous increases. Pre-stressed concrete roof girders price in 2024 for a complete element: span 12 m – 25000-35000 PLN, 18 m – 45000-65000 PLN, 24 m – 80000-120000 PLN, 30 m – 150000-200000 PLN.
Current rates in 2024 show that prefabricated g irders have an assembly price of 80-150 zloty/ton with a crane up to 150 tons. For heavier elements requiring cranes of 200-300 tons, the cost rises to 200-300 PLN/ton. In 2024, an apparent increase in fuel costs affecting transportation and assembly.
Price forecast for 2025
Predictions for 2025 indicate a possible price increase of 4-6% due to rising energy costs. Precast reinforced concrete girders price in 2025 will depend on the price of prestressing steel imported from China. The introduction of EU safeguard duties may raise costs by an additional 8-10%.
Low-carbon concrete girders reducing carbon footprint by 30% are expected to become widespread in 2025. The price of green roof girders will initially be 10-15% higher, but environmental subsidies may make up the difference. Automated production will reduce labor costs by 5-8%.
Cost comparison of different solutions
Economic analysis shows that roof girders prestressed price is 20-30% higher than steel for spans up to 18 m. Above 24 m, precast concrete girders become competitive. Precast roof girders total price over a life cycle of 50 years lower by 40% due to lack of maintenance.
Laminated wood structures cheaper by 15-20% for spans up to 15 m, but require fire protection. Steel-concrete composite girders more expensive by 30-40%, used for special architectural requirements.
Construction cost optimization
Reduction in reinforced concrete roof girder inputs price possible by optimizing spacing – 12 m instead of 6 m reduces the number of elements by 50%. Typification of cross-sections for the entire building reduces production costs by 10-15%. Combined orders for several investors give discounts of 8-12%.
Savings with prestressed concrete roof girders price by choosing the optimal span – it is often better to use more columns than maximum spans. Giving up gabled girders in favor of single-pitch girders saves 15-20%. Winter installation reduces the cost of cranes by 20%.
Operating costs of girders
Operation of prefabricated girders price of maintenance minimal – technical inspection every 5 years (500-1000 PLN), painting of steel elements every 10 years (50-100 PLN/girder). No maintenance of concrete throughout its life. Possible repair of mechanical damage PLN 200-500/m².
Modernization of prefabricated reinforced concrete girders reinforcement price when changing the purpose of the hall 500-1500 zł/mb. Additional external prestressing 2000-4000 zł/mb. Deformation monitoring system 50000-100000 zł for the entire hall.
Additional and hidden costs
In the calculation of the roof girder, the price should take into account: workshop and assembly design 5-10 zloty/m² of the hall, geotechnical research for the crane 5000-10000 zloty, temporary roads 100-200 zloty/mb, securing the yard 20-50 zloty/m²/month.
Additional elements affecting the roof girders price: bracing and braces 80-150 PLN/m² of the hall, purlins 100-200 PLN/m², roofing 80-250 PLN/m², skylights 500-1000 PLN/m², drainage 50-100 PLN/m².
The final prefabricated girders price of each project requires individual analysis of loads, ground conditions and utility requirements. We encourage you to contact us in order to prepare a detailed offer of the roof structure tailored to the parameters of your hall.
