1.The installation of stainless steel handrails and balusters have to be in accordance with the requirements and construction ink line from the starting point upwards.First install the balusters on the sides of the platform at the starting point.And there are two methods of installing including welding and bolting.The welding rod must be the same as parent material while welding.Spotweld and fix the balusters and buried pieces temporarily.Then weld and fix securely after marked elevation and vertical correction.While bolting the eyelets on the metal plate at the bottom of the stainless steel balusters must be processed to be oval so that the location of expansion bolts can be adjusted slightly.

  While constructing,joint and slightly fix the balusters after the electric drill drills holes and drives bolts into it at the bottom of the balusters.Adjust with metal shims if there is elevation inaccuracy.Fix the screw caps after vertical and marked elevation correction.After finishing installing the balusters on the sides,pull wires and install other balusters by means of the same method.The balusters of handrails must be fixed securely without being loose.The area of balusters welding and bolting except stainless steel must make anticorrosive and antirust processing after finishing installing.Ornamental covers or caps should be installed at the bottom without being exposed.

  2.Polymethyl methacrylate and glass and other railing panels are embedded into the balusters.These railing panels should be installed after finishing mounting balusters.They must be fixed securely and the uprightness,the levelness and pitch must be in accordance with the designing requirements.Embed the panels into the sockets of the balusters on both sides.Embed stereoplasm rubber stick into the aperture on both sides of the sockets and panels.Embed fluid sealant securely after installing handrails.The railing panels must be covered with fireproof asbestos cloth for fear that the welding spark might spoil the panels.

  3.The handrails except the ones that are of special dimensions are installed by welding.The welding rod must be the same as parent material.The installation must start with the initial connector bends before straightening the railings.The railing connector should be shorn right according to the required angle and be filed with metal file lest the shearing should be wrong and result in the railing bent and in difficulty of installation.First fix the initial connector bends and railing balusters by spotwelding while installing.Then weld securely after inspecting without any faults.After finishing installing connector bends,fix the straight handrails and balusters at either end by spotwelding temporarily.
  Meanwhile,joint the straight handrail with head at one end and then spotweld securely with 2-3mm welding seam left at the connector of handrails.After that,pull through wires and fix the handrails and each baluster securely by spotwelding.Weld securely the connectors,the handrails and balusters one by one according to the welding requirements after inspecting and being in accordance with requirements.While welding,especially in winter,the current,the voltage and temperature of welding must be appropriate lest the quality and beauty of welding should be influenced by improper current or unstable voltage.The quality of welding should be in accordance with the criterion of related regulations.The width and depth of welding seam should be the same.Also,the surface should be scaly.In addition,the seam of handrails and connectors should be welded strictly.The welding seam should have no distinct deviation.

  4.As for long metal handrails,especially for outdoor ones,movable connectors that can flex adapting to temperature change should be installed at the joint after installing handrails.The flex quantity should be ordinarily 20mm if there are no requirements in design.Also,leaking holes should be installed where it is flexible for outdoor handrails.Ordinarily,the junction of the handrail root,the concrete and the brick wall should also be fixed flexibly lest the handrails should bend out of shape for flexing.The root of the junction of handrails and walls should be installed with ornamental covers and caps.
