8 Core Methods for Reducing Costs of Small-Span Steel Structure Plants
8 Core Methods for Reducing Costs of Small-Span Steel Structure Plants
Design optimisation (reduce material consumption by 30%-50%)
Accurate load calculation of Steel Structure Plants
Select the optimal load rating based on actual usage requirements to avoid redundant steel usage due to over-design. For example, for a light warehouse Steel building without heavy equipment, the live load can be controlled at 0.3-0.5kN/m², which reduces steel consumption by 15%-20% compared with conventional design.
Adopting a standardised rigid frame system
Using a standard portal rigid frame layout with a plant roof slope of 1:10 and column spacing of 6-8m reduces steel consumption by 10-15% compared to non-standard designs. For plant with a span of 15-24m, variable section H-beams are preferred, and steel consumption can be reduced by 8% after optimising the section height.
Steel building of Lightweight enclosure system design
adopts 0.4-0.5mm thick single-layer colour steel plate (including galvanized layer Z80), which reduces the cost by 30% compared with sandwich panels; the heat preservation layer adopts glass wool with density of 12kg/m³ (75mm thick), which balances economy and heat preservation performance.
Material cost control of Steel Structure Plants
High-strength Steel building substitution
Using Q345 steel instead of Q235 in major load-bearing components (e.g. steel columns) can reduce the cross-section by 15-20 per cent after a 30 per cent increase in strength, reducing the overall cost by 5-8 per cent. Secondary components still use Q235 to ensure cost-effectiveness. -1
Reuse of used Steel building
Non-critical parts (e.g. walkway platforms, access ladders) can be made of second-hand steel that meets the specifications, reducing procurement costs by 40%-60%. Yield strength ≥195MPa to be confirmed by third-party testing.
Construction Technology Innovation of Steel building
Prefabricated Assembly Technology
Adopting bolted nodes instead of welding, the prefabrication rate is increased to over 85% and the construction cycle is shortened by 30%. A case study of a 24-metre-span plant showed that labour costs were reduced by 25 per cent.
Precision Lifting Solutions
Using a 25 tonne car crane instead of a 50 tonne machine saves 40% on the bench cost. Optimising the lifting path through BIM simulation to reduce machine standstill time.
Full-cycle cost management of Steel building
Foundation treatment optimisation
When geological conditions permit, priority is given to the use of 0.8-1.2m deep strip foundations instead of pile foundations, and the proportion of foundation cost can be reduced from 15% to 8%.
Long-lasting anti-corrosion technology of Steel Structure Plants
Choose epoxy zinc-rich primer (80μm) + acrylic polyurethane topcoat (60μm) coating system, with an anti-corrosion life of 20 years, which is one times longer than the maintenance cycle of ordinary coatings
