Description
Heavy duty steel grating are made by welding with heavy flat bar
and cross/round bars with certain distances. Our Steel Grating
enjoy the feature of high strength, light structure, high bearing,
convenience for loading and other properties.
Steel grating is hot dip galvanized processing, offers the
following advantages: saving materials, saving investment, easy
installation, durable in use, light structure, no accumulation of
dirt, good performance of ventilation, lighting, heat
dissipation,anti-corrosive, anti-acid an alkali corrosion.

Application
Steel grating can be widely used in petrochemical,water
plants,sewage treatment
plants,municipalengineering,environmental engineering and other
fields of platforms, walkways, trestlebridge, ditch cover, covers,
ladders, fences and railings etc.
Banding
Heavy duty gratings are commonly subjected to shock and impact
loads and it is highly recommended that all open ends be banded.
The welded band bar helps distribute impact loads and minimizes
distortion when subjected to repetitive traffic patterns. Banding
details can be found underSerrated Surface
Optional serrated bearing bars enhance skid resistance. Consider
this surface for applications subject to the accumulation of
liquids or lubricants or inclined grating installations.
