Q420qD Q420qE Material H Beam

 

 

Q420q is divided into 3 grades respectively: Q420qC=0℃ impact, Q420qD=-20℃ impact, Q420qE=-40℃ impact.

 

Q420qD h section column and Q420qE h beam iron are national standard bridge structure special steel. The implementation standard is: GB/T714 special technical conditions.

 

Q420qD/E steel grade in the Q = yield; 420 = steel yield strength unit Mpa; q = bridge structure special steel; D / E grade in the D / E = steel plate level.

 

Q420qD universal steel beams and Q420qE steel beam itself not only has very high strength but also has a certain toughness and fatigue resistance, impact resistance, corrosion resistance, welding and easy processing and other steel plate comprehensive quality performance. In the use of the process of high quality performance of the show has been unanimously praised and recognized by the manufacturing industry.
