    Climbing ladder

    • Species:carbon steel
    • Characteristic:The steel ladder beam and the step plate are galvanized after the whole welding, which overcomes the defects of the galvanizing and rewelding of the ladder beam and the treadle separately and destroys the galvanized layer, and the steel ladder is not deformed after the galvanizing.
    • Scope of application:widely used in urban road, square,graden,docks and airports,parking lot,highway,railway, industrial engineering and other kinds of industrial and civil architecture.

    1. Detailed information

    The metal ladder is a combination of steel tube ball joint armrest and steel staircase stairs. The material includes carbon steel and stainless steel, aluminum. The product conforms to 02J401 international standard. We provide finished products and easy to install. Hot-dip galvanizing treatment ensures convenient maintenance.

    1) the inclined ladder A adopts steel girders as side girders, and inclined ladder B and D as side girders of channel steel. There is a platform on the top of the tilted ladder.

    2) the form and type of steel grid trapezium, referring to the stairs pedals.

    3) the detailed structure and dimensions of the steel ladder should be referred to <02J401 "ladder diagram of building steel structure".

    4) when the angle of the steel ladder exceeds 45 degrees, the rail column of the steel ladder should be installed vertically on the side beam of the trapezoidal beam.

    5) according to the 02J401 assembly diagram of building steel ladder diagram, vertical ladder and straight ladder with protective cage can be provided.
