Types 

galvanized steel stair treads of China

no anti-slip requirement for welding ladder stringers

Characteristics

the type of steel grating which pitch of bars is 30mm is used most widely for all sectors of industry. It has the greates resistance to surface inpact.

anti-slip requirement for welding ladder stringers

 the type of steel grating which pitch of bars is 40mm is widely used in the industry field too. For the suitable interval of the bars so it always economical and weight-lightest.

no anti-slip requirement for connecting with ladder bolt

the type of steel grating which with pitch of bars is 60mm, cross bars pitch 50mm has been developed specially for mining industry and weight-lightest in all grating. In case of short spans they can meet a variety of uses.

 

anti-slip requirement for connecting with ladder bolt

1>High strength and light structure

2>Powerful anti-corrosion,durable and long working life

3>Beautiful appearance,bright surface

4>No dirt-rain-snow deposit,automatic cleaning,easy maintenance

5>Good ventilation,day-lighting,heat-dispersing,resistant to sliding and explosion.

6>Easy installation and disassembly
