Pressure locked grating is pressed the cross bar(steel bar flat) into the bearing bar or grooved bearing bar by pressure machine. This series of gratings with beautiful surface and light duty advantage. They are widely applied to underground, urban construction, port, theatre and other place that needs large loading--bearing capacity.
Pressure Locked grating is manufactured using hydraulic pressure to lock notched bars together. It provides excellent lateral support and has a clean, smooth look. It is not able to support the weight of rolling loads.
The superiority,application field and practical application of steel grating
Comparison with checkered plate,steel gratings has the following advantages: light weight,high strength,great load-bearing capacity, being economical of materials ,ventilation and light admission,modern fashion and non-slip and and safe, easy cleaning and installation, being sturdy and durable,etc.
Steel grating are widely used in:electric power,chemical plants,oil refinery,iron and steel works,paper mil,machine building factories,cement mils,municipal engineering,sewage treatment,medicine plants and foodstuff factories.

Packing of steel grating
Panels are bundle in a way most appropriate for handle by means of fork-lift or crane rope:two square lumbers are placed on the top and bottom of the bundle respectively. Six or four long bolts of M8 or M10 penetrate through the openings of the gratings and fasten the panels up.For the steel gratings of 3mm thick bearing bars,four pieces of angle steel are added between the bottom square lumber and the panel,to prevent from deformation when hoisting.Besides,special packaging standard as customer’s requirement are also available.
