Introduction to 15j401 steel ladder construction atlas

This atlas is applicable to new, reconstructed and expanded industrial and civil construction projects. It can be used for design selection, fabrication, construction and installation.

The main contents include: steel ladder of operation platform, steel ladder and platform steel guardrail, fixed steel inclined ladder, steel vertical ladder on roof, steel inclined ladder on roof, steel inclined ladder on crane, central column steel spiral ladder and plate steel spiral ladder.

This atlas revised the original atlas 02J401 Steel Ladder according to the new standards and specifications, improving the safety and economy of steel ladders. The stainless steel ladder, steel inclined ladder on the roof, steel inclined ladder with small slope, and steel ladder for maintenance of the upper trolley beam are added to further expand the scope of application.

This atlas is rich in content, diverse in variety, detailed in structure, and practical, which can meet the needs of design and construction.
