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.
