Description:

Steel gratings are constructed of bearing bars in longitudinal direction and cross bars which are in transverse direction.
 

The cross bars which line up in certain spacing are placed on the upper edges of bearing bars which stand up side by side; the computer-controlled welding machine electro-forges them into a single rigid grating panel which has strong welds and rectangular openings surface.
 

We prepare materials for steel gratings according to design drawings, and then pack them to delivery after edge-enclosing and hot galvanizing.

Steel grating has many advantages such as light weight, great load-bearing capacity, non-slip and safe, easy installation, being economical of materials, being sturdy and durable,   ventilation, easy to clean and attractive appearance

Steel grating are widely used by various plants such as electric power, petroleum, chemical industry, metallurgy industry, machinery industry, ship building, harbor, oceanographic engineering, building, paper mills, cement plant, medicine, spinning and weaving, foodstuff factory, transportation, municipal administration, parking lot, etc
