The material used in the stairs is undoubtedly expanded metal, and expanded metal stairs are known for their few welding fulcrums, quick installation, high load-bearing, many shapes and high technical content.

Steel structure stairs: high strength, light weight, fast construction speed, good seismic performance, easy installation and disassembly. Beautiful in appearance and reasonable price, DONGJIE expanded metal staircase is economical and practical, and has the characteristics of typhoon resistance, resistance, heat insulation, sound insulation, heat preservation and moisture resistance. However, steel structures have fire and corrosion problems. Therefore, during the production and installation of steel mesh stairs, the surface is treated with plastic spraying, galvanizing or baking paint.

At the same time, the steel structure stairs are strong and firm, and are not easily affected by structures such as columns and floors. The steel plates used in the expanded metal stair are all welded by precise debugging, so the treads are at the same level in the front, back, left and right after they are installed.
