Flat 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.Normally,hot-dipped 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 than 5mm,the weight of average Zinc Layer will not be less than 460g/m2.The quality
and requirements after hot galvanizing are subject to the standards of GB/T 13912 of China.The range pH6 to pH12.5,a stable protective film will
be formed on the zinc surface.It has good anti-corrosive property.
The grating packaging is usually piled on top,with wooden pallets at the bottom,packed in a packing belt for forklift and rope handling(as the
clients inquire)
The composite steel grating has high strength,light structure and strong anti-corrosion ability.
It is made of steel gratings of any type and steel plates with different thickness.The common specification is G323/30/100 with 3mm checkered
plates.
