Introduction of steel ladder

Steel ladders are suitable for heavy loads and can withstand heavy daily loads. A steel ladder is not a climbing ladder. Steel ladders are used for outdoor fire-fighting steel ladders. They are based on the atlas. The iron climbing ladder is made of simple steel bars for maintenance. Steel ladders are divided into two types: straight ladders and inclined ladders. Climbing ladders generally use round steel, and inclined ladder ladders are used as steel gratings and grid plates.

The steel ladder generally has a width of 600mm, 700mm, 800mm, 900mm, 1000mm, 1200mm, the small width is 600mm, and the large width should not exceed 1200mm. This is the standard for ordinary steel ladders. For a steel ladder with a width of 4400mm, 1.5kn is loaded at each symmetrical load of 600mm.

The width of the steel ladder is 4400, and the thickness is only 5mm. If for better safety performance, the steel ladder steps can also be made of toothed flat steel with excellent anti-slip performance. There are 4 types of steel ladders: T1 T2 T3 T4.

The width of the steel ladder 4400 chooses the thickness of the step board: the width of the steel ladder 4400 is indeed a relatively wide steel ladder. The width of this kind of steel ladder is small, and it needs to be done in terms of safety! The specifications and styles of the selected steel ladder step board must be able to meet the load-bearing needs.

Steel ladder treads, also known as stair treads, are deep-processed products made of steel grids, anti-skid strips and side panels. It is mainly used for steps on steel ladders, so it is usually called stair treads, or simply ladder treads. Steel ladder treads need to be produced in various sizes to match the corresponding stairs, but from the perspective of economy and safety, we recommend that you adopt the following specifications:

T325/30/100 (applicable to stair treads with a width greater than 215mm and not greater than 305mm)

T255/30/100 ((applicable to stair treads with a width greater than 215mm and not greater than 305mm)

Specifications of side panels at both ends: prefabricated building

The bolted steel ladder step needs to add 65X5mm flat steel to the steel grid as the side plates at both ends, and the side plates at both ends need to have holes.
