How to choose appropriate steel sheet thickness for each prefabricated workshop component
1. How does steel sheet thickness affect prefabricated workshops?
In prefabricated workshop structures, steel sheet not only acts as a cover but also bears wind load, rain load, and vibrations. If the thickness is unsuitable: The steel sheet sags easily when spanning large distances. It deforms easily under strong winds. The coating layer's lifespan rapidly decreases. Conversely, choosing an excessively large thickness for unnecessary items will lead to wasted initial investment costs.
2. Selecting steel sheet thickness for workshop roofs
The roof is an item directly affected by: Wind Heavy rain Continuous heat Common technical recommendations: Small – medium span: 0.40 – 0.45 mm Large span, high workshop: 0.45 – 0.50 mm Strong wind areas: priority ≥ 0.50 mm Besides thickness, a sufficiently large galvanised coating (Z180–Z275) is needed to ensure roof lifespan.
3. Steel sheet thickness for workshop walls
Workshop walls mainly bear: Lateral wind Light mechanical impact External environmental influences Commonly used thickness: Normal walls: 0.35 – 0.40 mm Walls outside industrial zones, humid environments: 0.40 – 0.45 mm For workshops requiring high aesthetics, electro-galvanised steel sheet (EG – Electro Galvanized) or EG/GA steel sheet can be considered for a long-term stable surface.
4. Do not just look at the “mm number” – actual thickness needs to be checked
In reality, many types of steel sheet: Declared 0.45 mm but actual thickness is lower. Errors come from the blank or coating layer. Therefore, upon receiving goods, it is necessary to: Measure with a micrometer Check multiple points on the sheet Cross-reference CO, CQ of the shipment. Actual thickness directly determines load-bearing capacity, not the number on the quotation.
5. Combine thickness and steel sheet width to optimize costs
An often overlooked factor is steel sheet width. For large workshops, using large width steel sheet from 1500mm upwards helps to: Reduce the number of joints Increase steel sheet stability Reduce material waste When combining suitable thickness + large width, the total cost of the entire construction project is often lower, even if the unit price/m² is higher.
6. Conclusion
Selecting steel sheet thickness for prefabricated workshops needs to be based on: Application item Span and height of the construction project Environmental conditions Actual thickness and coating layer This is an engineering – economic problem, and should not be decided solely by selling price.
