Handrails are very important in subway, walkways and Platform Bridge where handrails are needed to ensure the safety of the pedestrians and passers-by. And it is formulated by OSHA that in residential construction the handrails must be 42 inches high to guarantee the safety. And actually, the handrails of the living places are able to adjust their length in accordance with incline and the span of the buildings. Installing API steel pipe handrails in subway, walkways as well as places assemble many people where handrails are extremely needed to protect people from dangers like falling or sliding from the stairs when people are crowded is a significant thing that cannot be ignored.

First, you should make sure where the handrails will stand. The lengths of the handrails are different to meet the different demands. And then mark the center of the handrails places. Measure the step length, together with the length that is the distance between handrail places to the step, getting the distance between handrail place and handrail place. In order to get the length of each handrail, use geometric formula a^2 + b^2 = c^2 to figure it out. A represents the total values of the step height, b represents the measured length. After calculated with this formula, what we get is c which represents the estimated length of each handrail. And you must bear in mind that there should be two inches length for the installment of the elbow connectors. Thus, the final value is not the real value, you must minus 2 inches. And then you get what you really need values.

Guarantee the flange is placed on the concrete with the aid of the concrete screws, so that the mark of each handrail place is just on the central part. And then make a sign of holes in the flange to drill with a piece of chalk or pencil. Place one of handrails in the flange through the drilled hole and tap it into place with the help of a rubber hammer. Set the concrete screws on the one end of the flange and tighten them close with a concrete wrench to install the handrail in the right place and fix it. Next, attach elbow connectors on the top of the handrails and put it towards to the nearby handrail. And fix them with screws. Utilizing the handrail length makes it possible to put the handrails in a row and then place into the right places with screws to secure. And attach the handrails to the elbow connectors one by one and fix them with wrench as well as screws to make them tight.

After installing the last handrail and screws and making sure the flange is on the concrete with wrench and screws. Make the flange on the concrete place and the step in a row, and make a sign of the flange holes. Make holes on the top end of these signs and set anchors with the aid of the wrench to fix.
