Check the stair surface (precast concrete or iron frame) to make sure it is flat, not warped, and not bumpy.

Do not place objects exceeding 200kg on the steps.
B. During construction of plastic stairs
In case of installation on concrete stairs

Measure and adjust the size of the step neck, step strip and step surface to fit the size of the staircase that needs to be covered.

Cover the cross-section of the step with a step strip.

Cover the stair treads first and then attach the treads.

Perform installation from bottom to top.

Use a rubber hammer to lightly tap the step neck and step face after installation to ensure tight fit.

Apply glue to the joint between the wall and the stairs to prevent dust from entering.
