What Is a Metal Building?
A metal building is a prefabricated steel structure assembled from factory-manufactured components — primary rigid frames, secondary members, roof and wall panels, insulation, doors, windows, and accessories. Every component of a prefab metal building is precision-cut, welded, and drilled in a controlled factory environment before shipping to site for bolt-up assembly.
At Xinguangzheng, we manufacture pre-engineered metal buildings using portal frame rigid structures. Our 3 H-beam production lines produce up to 50,000 tonnes per year, with all welds inspected by our 21-member QC team. This is why our component quality pass rate consistently exceeds 99%.
We can achieve column-free spans up to 46 meters as standard, or up to 91 meters with custom truss design — depending on your required span, local wind and snow loads, and whether you need features like overhead cranes or mezzanine floors.
From our engineering team: The most common mistake buyers make is underspecifying local load requirements — particularly wind speed and snow load. Share your project location early so we can reference the correct codes (AISC, Eurocodes, BS) before quoting.
Our Metal Building Engineering Approach
With 40+ design engineers and 120+ total engineering staff, our in-house team handles structural analysis, detail design, and production drawings for every project.
Structural System Selection
For spans up to 30m, we recommend portal frames with 6–7.5m column spacing. For workshops with 10T+ bridge cranes, we design stepped columns with reinforced crane beams. For spans exceeding 40m, we use truss or space frame systems.

What Affects Metal Building Cost?
The cost of a prefab steel building depends on multiple factors. For an accurate estimate, submit your project details.
Building Size & Height
Width, length, and eave height directly affect material volume and structural design.
Structural Loads
Wind speed, snow load, seismic zone determine frame design. 150 km/h vs 100 km/h wind can add 15–25% steel weight.
Panel System
Single sheet, sandwich panel, or standing seam. Upgrading to 100mm PU adds $8–15/m².
Insulation & Energy
Climate zone and use determine insulation type, thickness, and energy efficiency requirements.
Doors & Accessories
Sliding doors, roller shutters, cranes, mezzanines can add 10–20% to base structure cost.
Shipping & Installation
Shipping distance, port access, local labor, and site conditions affect total project cost.
