Handrail – something for which we keep going down or up the stairs. Counter (sometimes called a "banister") vertical stand fixed in the stage or the floor. Top of the rack rail is fixed, parallel rails on the rack are prokidy (Beams, strings) to fill the space. In the case of childcare facilities for security reasons horizontal prokidy not install (that did not work like the ladder on which a child can climb), and establish several racks of smaller diameter (the fence) on which the top rail. Some differences of quality and correct stair railings: pipe is thin wall, the handrail is continuous, the number of crossbars 2, all welds zapolirovany to a state of homogeneity of the metal. Removed the color tint, appearing on stainless steel during welding. If the stairs can – racks walled. Prokidy and handrail in the field the end of the ladder guard will block, and should be on the line edge of the last stage.
Sometimes, for the stiffness, handrail gone into the floor. If the distance between the marches, more specifically, prokidy also continuous (tied) or put an additional rack. Standard and most common fence: handrail o50mm, o40mm stand, prokid (bar) 3pc o12-16mm. Rack-rail connection – through the "finger" o10mm, stand-prokid to welding. Stand in the walled stage. Rail connection to the welding of the most reliable, less reliable (but satisfying the requirements) on the mechanics (via Bochenko). Fencing (railing) with a connection through Bochenko, according to many, much richer and looks interesting.
If the crossbar (prokidy) bolted to the rack with screws – it's a bad fence. Preferably, choose an organization able to meet the maximum number of operation for the production ladder fences (rail) on its own manufacture to installation on site took the minimum possible time. The more so that usual mounting rail is carried out after completion of construction works. Ideal – a fence made sections, on-site installation and connection, welding, final polishing. Note that properly welded stainless steel with argon, so if the work is carried out on the street during installation is tied to the weather, wind or rain interfere argon-arc welding. Naturally this requires precise measurements, which produces the organization itself and the design study. Preferably, the presence of the Executive Design Bureau.
