T4 type steel ladder step grating plate with 40mm flat steel spacing is the lightest and most economical model. It is an ideal choice when the span is small. It adopts load flat steel and cross bar longitude and latitude to design a steel ladder step plate grating with rectangular grid holes. The side plate size of T4 type is 65mm * 5mm flat steel, and the bolt hole spacing varies according to the width of the step plate. See the parameter table for details.

T4 type steel ladder step plate with a spacing of 40mm has the strongest resistance in the scene of surface impact due to the small spacing of flat steel and 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
