When selecting a Chinese manufacturer for the fabrication and production of carports, quality control is undoubtedly one of your top concerns.
For welded steel carports, there are indeed numerous quality control points that warrant careful consideration.

How do Chinese national standard steels correspond to European standard steels?
The three most critical strength indicators for steel are: yield strength, tensile strength, and impact resistance.
European structural steel designs typically reference materials under EN 10219-1 conditions, commonly including S235JR, S275JR, and S355JR.
We compare the most crucial strength requirements for steel under both EN and GB standards.
From this, we can see:
1.1 Q235B fully meets the requirements of S235JR.
1.2 The correspondence between Q275 and S275JR is more complex. While yield strength and tensile strength can be matched, Q275 lacks a corresponding standard for impact resistance. Therefore, Q355B is recommended as a substitute.
1.3 S355JR can be fully substituted with Q355B. Not only do they match in yield strength and tensile standards, but Q355B also exceeds S355JR in impact resistance standards, offering superior strength.
