The main characteristics of material selection,welding and galvanizing:

1.Raw material requirements:The flat type mainly has:25×5mm,32×3mm,40×3mm,50×5mm,etc.The specification of package edge flat steel usually use this kind of flat steel which has the same width with the bearing flat steel and is not less than 5mm thickness.(such as:the specification of the bearing flat steel thickness is 32 x 3 mm,the specification of the wrapped edge flat steel is 32 x 5 mm).The twisted square steel diameter of width direction must be Φ8mm,the material must be carbon structural steel Q235A or 1cr18ni9ti stainless steel.

2.Welding process requirements:Each bearing flat steel and wrapped edge flat steel are both two-side fillet welding and the welding seam is not less than 3mm.

3.The joint of each bearing flat steel and twisted lever is full welding:After finishing the production of semi-finished black pieces,it must be removed splash,welding slag,burr and polished four corners with no sharp edges.The whole plate is flat.

4.The requirement for the galvanized layer:When the selected thickness of the bearing flat steel is not less than 5mm,the average zinc layer weight after galvanizing is not less than 610g/㎡;When the selected thickness of the bearing flat steel is less than 5mm,the average zinc layer weight after galvanizing is not less than 460g/㎡;The quality and requirements after galvanizing comply with the latest GB/T13912-2008 standard.
