Product Application
Steel grating, staircase, steel ball stanchion have a wide range of applications, primarily in industries such as manufacturing, construction, transportation, and municipal engineering. Specific applications include:
Stairs, operating platforms, and passageways used in workshops for machinery manufacturing, automobile assembly, electronic equipment production, etc. Their galvanized coatings can resist corrosion from oil and dust, and the perforated structure facilitates cleaning.
Mines and heavy industrial sites: Suitable for underground mine passageways, ore processing workshops, steel plants, and other elevated facilities and work platforms. The high-strength structure can withstand heavy impacts and frequent foot traffic.
In indoor stairs and passageways of large buildings such as commercial buildings, office buildings, and libraries, the galvanized appearance is clean, the anti-slip performance is good, and the perforated structure is conducive to air circulation.
Outdoor architectural facilities: These include outdoor stairs, fire escapes, roof platforms, etc., used in buildings. The galvanized coating provides excellent weather resistance, while the perforated structure allows for rapid drainage, preventing water accumulation.
Subway Stations and Train Stations: Applicable to staircases and passageways in subway platforms and train station waiting halls, as well as pedestrian overpasses connecting different platforms, with high strength and wear resistance to withstand a large number of people.
Pedestrian overpasses and underpasses: Stairs and walkways used in pedestrian overpasses and underpasses in cities.
It covers the drainage ditch and serves the functions of filtering debris and draining water. It is widely used in urban roads, parking lots, and other places.
Invisible manhole cover: used in drainage systems in municipal engineering, it is both aesthetically pleasing and practical.
Ventilation grille: used in ventilation systems in municipal engineering, it is both aesthetically pleasing and practical.
Used for petrochemical equipment platforms, skid plates, explosion-proof plates, etc., providing a safe working environment and protective measures.
Agriculture: Used for making livestock pens, farmland fences, orchard fences, etc., providing a safe agricultural production environment.
Steel grating stair treads and risers have advantages such as ventilation and light transmission, anti-slip, strong load-bearing capacity, beautiful and durable appearance, easy cleaning, and simple installation. Therefore, they are widely used in multiple fields.
