GB/T700 GB/T1591 Carbon Steel Plate Description
The equivalent material of GB/T700 Q275 carbon steel and low alloy steel plate is S275JR steel plate. S275JR steel plate is a general-purpose carbon structural steel. This steel is similar to the steels listed in China GB/T700 and GB/T1591. It is also a carbon structural steel and low alloy structural steel used in engineering steel and structural steel, which is usually not heat treated. GB/T1591 steel plate is a Chinese standardized low alloy medium tensile strength steel plate produced by hot rolling process. GB/T1591 steel plate has a variety of manufacturing purposes.

Galvanized coils are our top choice for durability and
consistency.
The zinc layer
uniformity saves us time in post-processing, and your team's technical
support is
always
helpful.

We have been purchasing yulun galvanized steel coils for
the quality
has
consistently exceeded our expectations. The coating uniformity, corrosion
resistance, and
surface finish meet our strict standards, making them ideal for
construction.
