China Xin Guang Zheng Steel Structure on Waterproofing in Steel Structures


Compared to traditional concrete buildings, steel structures possess unique characteristics. As China Xin Guang Zheng Steel Structure buildings are assembled and overlapped on-site using various components, panels, and other materials, waterproofing primarily relies on drainage over sealing as a supplementary approach.
Currently, waterproofing materials for steel structures demonstrate suboptimal effectiveness and limited longevity. Thus, architectural configuration, drainage planning, and structural design become critical in waterproofing steel buildings.
In practical projects, the following measures ensure or enhance waterproofing performance:
Architectural Configuration
Prefer a single-ridge design to avoid interior gutters.
Use exterior gutters instead of interior ones where edge gutters are necessary.
Select roof panel profiles based on drainage slope and span: opt for higher wave-height panels for shallow slopes or long spans.
Drainage Planning
Strategically position drainage points according to regional rainfall intensity.
Base drainage design on hydrological data, not subjective assumptions.
Structural Measures
Master and flexibly apply standard steel structure waterproofing details.
Mandatorily deploy waterproofing materials where required.
Finally, leaks in steel structures often stem from construction flaws rather than design errors. Strict quality control during construction is essential for effective waterproofing.
