Steel Structure Project Estimator

Get a preliminary tonnage, budget range and factory-to-site timeline in under a minute. The numbers come from rules of thumb we apply to 500+ delivered projects since 1999 — then our engineers refine them against your drawings, free of charge.

Fill in the fields below. The estimator returns a planning range — a binding quotation always follows a drawing review by our engineering team.

Estimated Steel Tonnage
330 - 450 t
Budget Range (USD)
USD 0.43 - 0.72 M
Shop Drawing
3 - 4 wks
Fabrication
6 - 8 wks
Sea Freight
3 - 5 wks
Expected Total Lead Time
12 - 17 wks
How to read this: tonnage includes main frames, secondary steel, bracing and typical connections (excludes cladding, foundations, deck and MEP). Budget is an indicative FOB + design + fabrication range in USD and does not include freight, duties or site erection. Final numbers depend on drawings, local codes, wind/snow/seismic loads and site conditions.
Engineering Basis

What the Numbers Are Based On

These unit rates come from our fabrication records and project database. They are the same figures our estimators use before opening Tekla — shared so buyers can plan budgets and financing early.

Structure Type Typical Unit Rate (kg/m²) Typical Span (m) Fabrication Rate (t/week)
Portal frame — warehouse / factory 28 – 40 18 – 36 250 – 500
Prefab sandwich-panel building 22 – 32 12 – 30 250 – 450
Space grid (bolted sphere) roof 18 – 32 24 – 80 200 – 400
Pipe truss — long-span roof 32 – 55 40 – 120 200 – 350
Multi-storey / composite frame 45 – 85 8 – 16 bay 150 – 300

Rules of Thumb, Explained

The span penalty is real: a 36 m portal frame carries roughly 12–18% more steel per square metre than a 18 m one, because member depth and connection moments grow with span. The region factor reflects design loads — a roof sized for EN 1991-1-3 snow in Germany carries more steel than the same area in Dubai, where wind dominates.

Fabrication rates assume our Xuzhou plant with 200,000 t annual capacity, 8 CNC lines and two blasting-painting booths. Small orders are slower per tonne (setup dominates); very large series are faster.

What is Included in the Budget Range

  • Structural steel design review and shop drawings (Tekla / AutoCAD)
  • S355 / Q355B fabrication, blast-cleaning Sa2.5 and two-pack painting
  • QC inspection: weld map, NDT, dimension survey and packing list
  • Sea-worthy packing (bundles, slings, plywood protection)
  • Factory test certificates and material mill certificates

Excluded: cladding, foundations, erection and freight — the freight section below tells you what sea freight typically costs to your region.

Logistics Planning

Typical Sea Freight Time from Chinese Ports

Budget USD 45–110 per tonne for shipping and port handling depending on destination and packing method (break-bulk vs container).

Destination Transit Time Indicative Freight (USD/t)
Southeast Asia (Singapore, Jakarta, Ho Chi Minh) 1 – 2 weeks USD 45 – 65
Middle East (Jebel Ali, Dammam, Hamad) 2 – 3 weeks USD 55 – 75
West Africa (Lagos, Tema, Abidjan) 4 – 6 weeks USD 80 – 110
Europe (Rotterdam, Hamburg, Piraeus) 4 – 5 weeks USD 70 – 95
North America (LA, Long Beach, Houston) 3 – 4 weeks USD 75 – 100
South America (Santos, Buenos Aires, Callao) 5 – 7 weeks USD 85 – 110

Rates are indicative for 2026 bulk steel cargo and vary with bunker prices, port congestion and container availability. Ask our logistics team for a CIF/DDP quotation to your exact port.
