Product Details
Steel bar grating with high strength and firm structure is made up
of carbon steel, aluminum steel, or stainless steel. According to
the manufacturing methods, it can be divided into four types:
welded, press-locked, swage-locked, and riveted gratings. According
to the surface shapes, it can be divided into smooth and serrated
gratings. With various styles and sizes for choice, steel gratings
are widely used in everyday life, such as stair treads, walkways,
platforms, floors, various covers, wheeled equipment, security
screens, heavy-duty constructions, and so on.
Surface Treatment
We provide four finishes for anti-corrosion treatment of carbon
steel bar grating:
Black / Bare Steel: No finish, life is very short, but the price is
the cheapest.
Painted Coat: The anti-rust effect is general and can be any color.
Electro-galvanized: A small amount of zinc coating, easy to cause
slight corrosion in humid environment.
Hot-dip galvanized: The most commonly used method to provide the
best anti-rust effect, strictly in accordance with ASTM A123 or
GB/T 13912-2002.

GNEE Steel Grating Application
Steel grating are designed and manufactured for various industrial
and civil constructions in city road, gardens, yard, airport,
railway and industrial engineering.
- Hot dip galvanized steel grating is the best choice for steel
platforms in airports. Grating with 30 × 3 mm thick load bearing
bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is
the suitable one.
- Steel grating, with robust design and spanning abilities, is very
strong and safe for the support of floors and elevated walkway. It
can be used for ceiling, interior decoration, platform aisle,
ventilation windows, (Wells), advertising plaque and other
construction.
- Widely used in the petrochemical industry, power plants,
