Q235NH tower steel sheet physical properties

Common Q235NH tower steel sheet, steel plate thickness specifications are as follows:
Thick steel plate: thickness greater than 4, width within 10 is less than 2000mm, width above 10 is generally 2000, 2500mm, length 4-12m;
Thin steel plate: thickness less than 4mm, width 500-1500mm, length 1.5-4m;
Flat steel: thickness 4-60mm, width 12-200mm, length 3-9m.

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce Q235NH tower steel sheet, hot-rolled seamless steel tube by continuous rolling mill.

In order to improve the Q235NH tower steel sheet corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main Q235NH tower steel sheet coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking Q235NH tower steel sheet sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
