The installation from the embedded parts of the particular stair railing can only be as well as the embedding method, its practice should be to use expansion bolts and steel plate to produce the rear connector, first inside civil base on this line, to determine the position of the column fixed point, then on the floor in the staircase with impact drilling drilling, after which you can install expansion bolts, bolts not to lose sufficient length, after that bolt positioning, Tighten the bolt along with weld the nut with the screw to prevent loosening on the nut and the steel plate. Handrails and walls connected with decent connection also take the identical approach. Glass Railings
Welding column, the need for a two-person assistance, a hold the steel pipe to hold it vertical, in the welding cannot be shaken, another person to utilize welding, to be around to utilize welding, and should comply with the welding specifications. The column is machined out of the groove at the top in the staircase by stretching the line and putting the line around the angle of the stair as well as the roundness of the armrest. Then position the armrest directly into the particular column groove, from one end into the other end of this installation of spot welding, next handrail installation butt specific, tight seam. After the particular adjacent steel pipe is usually docked, weld the seam with metal electrode. Before welding, should be along the weld seam each side in the $number range of essential oil, burrs, rust and alternative cleaning. Laminated insulated glass
After all welding, use the hand wheel grinding machine to flatten the weld, until the weld isn't obvious. Polished with cotton grinding wheel or felt for polishing, and the corresponding polishing paste, until similar to adjacent to the starting material, do not present the weld. With cross section 40mmx80mm along with 40mmx100mm square wood each and every 1 pieces (among which often 40mmx100mm square wood in accordance with the column bar spacing along with the quantity lofting saw Chisel on the gap), square wood time-span with armrest, will the column steel bar into your square wood gap, Then 12th wire will be two pieces of square wood temporarily associated with the top of the particular column about 50mm out, and then the general correction column and service.

At the top of the column, the'll brand is played, then the graphite stroke line must be used, and the top surface on the column is blown into'll outside by oxygen cutting. Welding Handrail Hair straightening iron, then in the hair straightening iron bends, warping, with acetylene heated red following dial positive, and right away boil water cooling, correction hair straightner. Then the welding corner hair straightener, to the end on the handrail at the ends from the connection corner flat iron bars welding, remove the tie from the column bar top belonging to the square wood. Weld ornaments. Set up wooden or plastic handrails. Glass Railings.
