Steel grating is a kind of widely used grid products. They are used
in various industrial fields and has the strongest resistance to
surface impact.
According to the shape of the surface,they can be divided into
tooth-shaped steel grating, pressure welded steel grating, I-type
steel grating and composite steel grating.
According to the surface treatment,they can be divided into hot-dip
galvanized steel grating, spray paint steel grating, stainless
steel grating and original steel grating.
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.
The products are used in such industries as petroleum and chemical,
port, power, transportation, papermaking, medicine, steel and iron,
food, municipality, real estate, manufacturing, etc. And it
exported to Australia, South-east Asia, Middle East, Japan,
South-Korea, Trinidad, Singapore, New Zealand and so on.
Main products include steel grating, stair treads & industrial
ladder, trench grating cover, handrails, grating clips, cable tray
, which are used in Petrochemical Industry, Oil Fields, Boiling
Platform, Seaport and Vessel Construction, Power Plant, Industrial
Floor Platform, Municipal Engineering and so on. 70% products are
regularly exported into USA, Latin America, Australia, Kuwait, UK,
France, Japan and Southeast. So now our company owns a better
reputation in the world and complete many global big projects with
foreign partners together.
