The step board is processed from steel grating (steel grating is a type of steel product made by crossing flat steel with horizontal bars at a certain distance and welded into a square grid in the middle). The surface of this product is generally treated with hot-dip galvanizing or electroplating galvanizing.

Stair treads are used as industrial platforms, stair treads, handrails, channel floors, railway bridge side tracks, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional parking lots, fences for offices, schools, factories, enterprises, sports fields, garden villas, as well as external windows for residential buildings, balcony guardrails, guardrails for highways, railways, etc.

The size of stair treads is determined based on the opening, depth, and floor height of the staircase, determining the height and width of each stair tread, the length and width of the staircase, and the width of the platform.

Several installation methods for stair treads

Method 1:

① Recheck the height of the stairs to see if it matches the height on the drawing.

② Determine the position of the hanging and base on the stairs, and for L-shaped structures, the detailed location of the ground or wall support at the turning point must also be determined.

③ Once confirmed, fix the installation of the upper hanging and base stair treads

Method 2:

① Remove the step board, determine the installation position of the stair step board, and gradually install it from top to bottom. For those with small step supports, adjust the height of the small supports, and then drill holes to connect the small supports to the step board without fixing them

② First fix the step board, then fix the small support.

③ Follow the above steps to install the staircase fence at each step

Method 3:

① First, determine the location of the required installation column and drill holes to install the column

② Fix the column base, loosen the accessories on top, and install wire drawing

③ After the wire drawing and handrail are installed and adjusted to the appropriate position, fix all fence posts
