Preservation of steel sheets and steel outside the construction project to prevent rust before construction
Why is it necessary to properly store steel sheet and steel at the construction project?
During the construction of factories, residential houses, or industrial construction projects, steel sheet and steel are often imported before installation. If not properly stored, the material can rust, scratch, or warp, affecting quality and construction costs.
Especially with types such as galvanised steel sheet, electro-galvanised steel sheet, EG steel sheet, GA steel sheet, or wide steel sheet, improper storage can reduce the lifespan of the coating and cause the construction project to degrade faster.
Reasons why steel sheet rusts before construction
- Placing steel sheet directly on damp ground
- Not covering when it rains
- Placing steel sheet against a wall causing water accumulation
- Incorrect stacking technique causing scratches to the coating
- Storing too long outdoors
When the coating is scratched or damp for a long time, oxidation occurs quickly and creates rust, reducing the durability of the material.
Proper steel sheet stacking technique when stored at the construction project
Steel sheet should not be placed directly on the ground. It needs to be supported by wood or pallets to create a distance from the surface.
- Minimum support height: 10 – 20 cm
- The ground must be dry and flat
- Do not support unevenly causing steel sheet to bend
How to cover steel sheet to avoid rain and moisture
When leaving steel sheet outdoors at the construction project, it needs to be covered with a tarp but not completely sealed.
- Cover completely on top
- Both sides must be airy
- Avoid condensation inside
Many construction projects cover completely, causing moisture to be trapped, making steel sheet rust faster.
Notes when stacking large quantities of steel sheet
- Stack in the correct wave direction
- Do not drag steel sheet on the surface
- Do not place heavy objects on top
- Do not mix with sharp objects
With wide steel sheet or flat cut steel sheet, incorrect stacking can cause bending or scratches to the coating.
Steel sheet should not be stored too long outdoors at the construction project
Steel sheet should be used within a short period after arrival.
- Best: use within 1 – 2 weeks
- Should not be left outdoors for months
- Especially electro-galvanised steel sheet needs careful storage
The role of proper transportation technique
In many cases, steel sheet is scratched upon delivery due to improper transportation.
- No rubber lining
- Not securely fastened
- Non-specialized vehicle
This reduces the quality of the coating before construction.
