Moreover, these specialized rebars and steel materials have undergone special treatment and forging, which were not available when Lao Lin arrived.
The previously used rebars were merely elongated iron rods, and there were no patterns on them. It wasn't until Lao Lin arrived that he specifically had them improved.
It can be said that the steel currently in use is almost the same as solid steel, although it doesn't achieve the same level of refinement nor the strength of solid steel.
But at least, it's far stronger than the existing ones today.
Furthermore, even though the current steel isn't as strong or robust as future materials, one thing must be acknowledged—its usage rate is quite high. In essence, originally there were four pieces of steel on a single bearing column, but here there are as many as ten, potentially even more.
In other words, to compensate for the lack of quality, the quantity is increased to ensure the safety of the structure.
