1.Normally ,Hot galvanizing will be carried out after end welding process , When the thickness of bearing bars is not less than 5mm,the weight of average Zinc Layer will not be less than 610g/m2
.When the thickness of bearing bars is less then 5mm,the weight of average Zinc Layer will not be less than 460g/m2 . The quailty and requirements after hot galvanizing are subject to the standards
of GB/T 13912.
2.To gain protection layer through the ways of spraying,brushing and soaking.
Bar grating is made by the world first-class Italian ORSOGRIL equipment .which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance .Cross bar is pressed
into the bearing bar by high tension resistance weldingring which is controlled by computer ,So we can produce high quality gratings with firm welding ,smooth surface and high strength.
Surface Process of Gratings
Certified by ISO9001 .
the factory price should be more competitive,Our factory mainly products wire mesh fence and Steel frame lattice.
