The T4 type steel ladder tread plate with a spacing of 30mm is the most resistant type to the surface impact. It adopts the flat steel and the fried dough twist steel with load performance and is welded into a steel ladder step board with rectangular grid holes according to a certain distance. The two sides of the T4 model are fixed flat steel size 65mm*5mm: bolt hole spacing is different according to the width of the tread board, see the parameter table in detail.

T4 type steel ladder step plate with a spacing of 30mm has the strongest resistance in the scene of surface impact due to the small spacing of flat steel and the high density of load flat steel. Moreover, the hot-dip galvanizing treatment process can make it more corrosion-resistant. It is most widely used in the industrial field. In addition, its grid hole structure can show advantages in rainy and snowy weather, free from manual maintenance and cleaning. Compared with concrete structure, this material has the advantages of light structure and low price.
This specification has multiple width recommendations in the attribute table, and a variety of flat steel section specifications correspond to different widths and lengths. If you need to customize, you can refer to the length and width in the drawing design to select the corresponding flat steel model recommendations. Please send the request to email: info@cnkaiheng.com
