Step Plate and Steel Step Plate

Step plate

Step plate,  is one of the types of steel grating stairs for platform, according to the installation, general welding, and the screws of the two major type, welded directly to the keel don't need to add the step plate on the side plate, a relatively economic and durable, but the same in dismantling. Bolt fixed step plate on both sides need to thicken the side panel, punchs a hole on the side panel, installation is bolted directly, can be recycled in use. Can be customized according to own actual need, can be used for any type of steel grating made into various sizes, corresponding to the stairs. With novel and attractive, durable, fast installation, no maintenance, etc; Widely used in mining, electric power, petrochemical, light industry, waterworks, sewage treatment plant, etc.

 

Step plate type and size:

Commonly used step plate width is 700 mm, 800 mm, 900 mm; The minimum width is 600 mm, maximum width should not be greater than 1200 mm.

For single through the step plate, the two oblique beam or the width of the barrier between should not be less than 600 mm.

When frequently under a few people at the same time cross through the stairs or when used for personnel evacuation route, ladder should be increased to 1200 mm wide.

Step plate made of steel grating model according to the standard steel grating YB - T4001.1-2007 appendix E reed to choose.

Stair step plate  along the should be able to withstand a load of 1.5 kN, when the width is not more than 1200 mm, the load on the 100 mm x 100 mm area; When the width is larger than 1200 mm, 600 mm per symmetrical loading is 1.5 kN, stair step plate deflection shall be not less than 1/500 of the span.

Stair step plate and ladder, platform should possess good skid resistance.

Adjacent two pieces of up and down the stair step plate of vertical projection of the lap part should be not less than 10 mm.

 

Step plate  form:

 

T1 is used for welding installation, bearing flat steel plate used on both ends with the same flat package edge, no front guard board.

T2 for bolt installation, both ends with 65 x 5 flat bag edge plate and open hole, no front guard board.

T3 is used for welding installation, bearing flat steel plate used on both ends with the same flat package edge, a former guard board

T4 used for bolt installation, both ends with 65 x 5 flat bag edge plate and opening, a former guard board
