Steel gratings are generally made of carbon steel, and the surface
is hot-dip galvanized to prevent oxidation. It can also be made of
stainless steel. The steel grating has ventilation, lighting, heat
dissipation, anti-skid, explosion-proof and other properties.
Steel grating is an iron product with a square grid in the middle
that is welded by a pressure welding machine or manually. Steel
grating is mainly used to make ditch covers. Plate, steel structure
platform plate, steel ladder step board, etc. Crossbars generally
use twisted square steel
Steel grating is suitable for alloys, building materials, power
stations, and boilers. shipbuilding. It is used in petrochemical,
chemical and general industrial plants, municipal construction and
other industries. It has the advantages of ventilation and light
transmission, anti-slip, strong bearing capacity, beautiful and
durable, easy to clean and simple to install. Steel grating has
been widely used in various industries at home and abroad. It is
mainly used as industrial platforms, ladder treads, handrails,
passage floors, railway bridge sideways, high-altitude tower
platforms, drainage ditch covers, manhole covers, road barriers,
Three-dimensional parking lots, fences for institutions, schools,
factories, enterprises, sports fields, garden villas, and can also
be used as exterior windows of residential houses, balcony
guardrails, highway, railway guardrails, etc.
