steel grating weight:   Galvanized Steel Grating is a kind of open steel member with its bearing bars & cross bars jointing at their intersections either by welding or by locking.   Galvanized Steel Grating is made by stainless or mild steel of certain sizes through the processing of grooving, lock-pressure, welding, finishing and other treatment. Industrial bar gratings can be actually made from copper, aluminum and other materials, while galvanized Steel Grates is the mostly used one due to its economic cost and good property.   General Usage of Galvanized Steel Grating:  

Flooring	all kinds of Trench cover
Catwalk	Window and machinery safe guards
Mezzanines/decking	Wash rack
Stair tread	Ventilation screen
Fencing	Storage rack
Vault bin floor	Suspended ceiling
Ramp

  Galvanized Steel Grating Panels Types: There are three kinds of steel gratings distinguished by different bearing bar types. The respective of features are as follows: 1) Plain: the most widely used gratings,available for flooring sidewalk,all kinds of ditch cover,stair tread,etc. 2) Serrated:best non-skid property & safety compared with plain grating. 3) I-shape:lighter,Not substantially weaken the case of load capacity more economical and practical comparing with plain grating.   The Most Popular Specification of galvanized Steel Grating: 1) Steel grating with 30mm bearing bar pitch is the most widely used in industrial area.Among the general series.it maintains the strongest resistance to impulsive force. 2) Steel grating with 40mm bearing bar pitch is one of most ecnomical & lightest types.It should be the best choice to customer on the occasion when the clear span is small.
