同一套图纸，海边和山区、热带和北欧的用钢量可以差 30%。荷载参数决定一切。The same drawing can need 30% more steel by the sea or in the mountains. Loads decide everything.
收到客户询价时，我们的工程师一定会追问三个参数：基本风压、雪荷载、地震设防。因为同一套 40×80m 厂房图纸，在不同环境下的用钢量差异可达 30%。
风荷载：沿海台风区（如菲律宾东部）基本风压可能是内陆的三倍，直接影响檩条间距、柱距与支撑布置。
雪荷载：北欧、中亚部分地区的雪压值是设计主导荷载，屋面坡度、檩条截面都因此改变。雪荷载大的地区还要考虑不均匀积雪工况。
地震作用：设防烈度决定节点延性与支撑体系，多震区不建议盲目减小用钢量。
所以一份专业的报价，必须始于对项目所在地的了解。只给面积就报价的供应商，省掉的其实是对您结构的尽责。
When a quotation request arrives, our engineers always ask three things: basic wind pressure, snow load and seismic intensity. The same 40×80m workshop can need 30% more steel depending on the environment.
Wind: in coastal typhoon zones (eastern Philippines, for example), basic wind pressure can be triple that of inland sites — directly affecting purlin spacing, column grid and bracing.
Snow: in parts of Northern Europe and Central Asia, snow governs the design — roof slope and purlin sections follow, and drifting-snow cases must be checked.
Seismic: design intensity governs joint ductility and bracing systems. In seismic zones, never cut tonnage blindly.
A professional quotation starts with knowing the site. A supplier who quotes from floor area alone is skipping the diligence your structure deserves.
