Diamond safety grating stair treads are produced with welded end carrier plates, it uses the same materials with plank. The pattern can be 2, 3, 4, 5 diamonds. The stair treads are divided into standard stair treads and stair treads with nosing. The standard stair treads can be used life, traffic, etc. The stair treads with nosing are more high slip resistance, it has a special usages for industry.
