Handrail

Note:

1.Steel Pipe Dimensions: In the above table, dimensions before the bracket are for carbon steel, while those in the bracket are for stainless  steel. However, all final dimensions must be subject to drawing confirmation of both parties.

2. Stanchion Spacing: 1,000, 1,200 and 1,500 mm

3. Height of Handrail:

   (1) Double Rails

　　A. Horizontal Handrail: with a minimum height of 1,100 mm for the handrail

　　B. Angled Handrail: with a minimum vertical height of 900mm for handrail

   (2) Three Rails: generally 1,200mm

   (3) Single rail or more than 3 rails are subject to specific design.

4. Joint of Rail and Stanchion:

   (1) Welding is generally adopted for joints with parcel antirust treatment.

   (2) Bolts or pins are optional, with necessary holes to be drilled at site for installation.

5. If customer reduces the height of handrail or the thickness of steel tube, or increases the main stanchion pitch, etc. so as to save cost, Wellter will not be responsible for any consequences incurred.

I. Horizontal Work

1. Where there is sufficient room...

(1) Space out stanchions and lay rail tubes alongside where handrail is to be erected.

(2) Pull stanchion onto pipe from either end to opposite where they are to be fixed.

(3) Stand up system and temporarily bolt both end stanchions for safety.

(4) Position and bolt intermediate stanchions. Pack either side of base plate with shims to align system if necessary.

2. Where there is insufficient room ...

(1) Fix the end stanchion securely in position, then feed both handrail and kneerail into stanchion while supporting other

end of pipe until other stanchions can be placed.

(2) Place a brick or similar support under base plate until nex stanchion is fed onto pipe.

(3) Move brick to this stanchion and proceed to pull previous stanchion along pipe to its final position.

(4) Bole loosely and repeat operation as previous sequence.

II. Stairway Work

(1) Start at bottom of first flight and work up for SAFETY.

(2) Bolt bottom stanchion securely in position, then the second stanchion loosely in position.

(3) Feed the pipe down through No. 2 stanchion and just enter No. 1 halfway. Allow free end to hang.

(4) Feed mid rail through No. 2 stanchion and right through No. 1 approx. 75mm.

(5) Fit and securely fix angle closurer bend, either by slip joint and taperpin or tack welding.

(6) Feed and fix additional stanchion and tighten.
