The dealers are specializing at super thick steel Grade DH36 plate that is beyond the approval of nine classification society. We have cooperated with LR, DNV, CCS, ABS, BV, GL, NK, KR, and RINA to do the third party inspection to promise quality for our customers in many years.

Testing of the LR Grade DH36 material shipbuilding steel plates

There at the manufacturing plant to assure that manufactured ranges of Grade DH36 PLATE are of superior quality, the testing is conducted. The tests are like positive material identification test, hardness test, intergranular corrosion test, pitting resistance test, mechanical test, chemical test etc are conducted.

Documenting of the Grade DH36 material shipbuilding steel plates

The documents by the suppliers to their clientele are provided essentially to assure that when the deal is done, 100% fairness is maintained. The ranges of documents offered to the buyers are commercial invoice, packaging list, heat treatment chart, raw material test report, material traceability report, guarantee letter. Also, they offer mill test certificate to the buyers as per EN 10204/3.1B.

Packaging at the industry

For assuring that after doing a lot of hard work and putting greater efforts in manufacturing the stunning quality of Grade DH36 steel plates, no damages should ruin its quality. Thus the packaging of the plates is done by using the plywood cases/pallets and is wrapped into environmental poly bags.

Q420qC structural steel plate supply

Q420qC material is a structural steel plate for bridges. Q420qC plate are produced according to the Chinese standard GB/T714.

Q420qC steel grade analysis:

Q represents the first letter of the Chinese Pinyin of "qu" which represents the yield strength of steel for bridges;

420 represents the yield strength value in MPa;

q represents the first letter of the Chinese pinyin of the word "bridge" for bridge steel;

C represents the C level of the quality level.

When the Q420qC steel plate is required to have weather resistance or thickness direction performance, the Chinese pinyin letter "NH" representing weather resistance or the symbols Q420qC-Z15 and Q420qC-Z25 in the thickness direction (Z direction) performance level shall be added after the above-mentioned grades respectively. Q420qC-Z35.

Q420qC steel manufacturing

Q420qC steel plate is smelted by converter or electric furnace, and should be refined outside the furnace.

Q420qC steel plate size, shape, weight and allowable deviation

The size, shape, weight and allowable deviation of structural steel plates for bridges should meet the standards of GB/T 709.
