Practical Notes

Verify the thickness of the steel sheet used for shelves and the main body, as using undersized sheets is a common cost-cutting measure that reduces durability.

Ensure proper surface preparation like phosphating (as per IS 6005) is done before painting to prevent rusting and peeling.

Check for sharp edges and burrs, especially at welded joints and corners, to ensure user safety.
