The biggest feature of this product is its targeted anti-slip design for stair steps. The serrated surface treatment increases the anti-slip coefficient to more than 0.8, effectively reducing the risk of pedestrian slipping when walking up and down stairs, especially in rainy or wet environments. The hot-dip galvanizing treatment forms a dense protective layer, extending the service life of the stair treads to more than 10 years. The one-piece molding design ensures the overall strength and stability of the stair treads, avoiding the problem of loose components during long-term use. It complies with the JGJ 120 Chinese building stair safety design standard, ensuring the safety and compliance of the product.
This product has a standard size of 1000mm in length and 250mm in width, with a plate thickness of 5mm, grid aperture of 30x80mm, flat steel width of 30mm and cross bar spacing of 80mm. The anti-slip coefficient reaches ≥0.8, meeting the anti-slip requirements of building stair steps. The load capacity meets the C200 grade standard of 200kN/m2, suitable for carrying daily pedestrian and light-duty goods. The surface zinc layer thickness is no less than 85μm, with excellent corrosion resistance. It supports custom sizes according to the specific stair dimensions of the building, adapting to various stair layout requirements.
This stair tread steel grating plate is mainly applicable to the stair steps of industrial plants, factory workshops, public buildings, shopping malls, subway stations and other places. It is suitable for both indoor and outdoor stair scenarios, providing a safe and durable walking facility for personnel going up and down stairs. The anti-slip design ensures the safety of pedestrians in wet or rainy environments, and the hot-dip galvanizing treatment ensures long-term service life in outdoor scenarios. It can also be matched with stair handrails and other matching components to improve the overall safety of the stairs.
