As an experienced engineer who has been working on bridge construction sites for decades, I am well aware that the appearance quality of precast T-beams is not only a facade project, but also a direct reflection of their internal quality.
A T-shaped beam with a smooth appearance and uniform color often means that its internal quality can withstand the test.
The beams with honeycomb and pockmarks on the surface and staggered cracks may also have hidden quality hazards.
