Q235B Raw Steel Material Multi Storey Steel Building With Painted
Or Galvanized Surfacement
Product Description:
Being an Ideal solution for commercial building, the construction
speed of multi storey building is faster than other conventional
buildings due to usage of high level of material pre-fabrication,
designing accuracy, best quality checks and riskless construction.
Classifications of multi storey steel buildings:
- Depending on the height, need and various other factors, multi
storey buildings are classified into following.
- Low Rise building: A low rise multi storey building has few storeys
(typically less than four), with the usage of elevators and stairs
for vertical circulation.
- Mid Rise building: A Mid Rise building has number of storeys
ranging from 4 to 12.

Floor Structure
The floor has sufficient stability, strength, and rigidity. At the
same time, the thickness of the floor slab should be reduced to
increase the net height of the indoor. Corrugated metal floor
deck-concrete composite floor covers are currently widely used.

Selection of fillet weld size
Based on the standard and our experience and actual process, the
requirements on the fillet weld size should be as followings(in
terms of when there is no request on drawing but there is
inspection request):
Form of fillet weld leg | K(fillet weld size) value | Note |
Fillet weld without groove | K=(0.7~1)t and ≤15mm | for most of the steel structure buildings |
K=(0.5~0.6)t | for the strengthening ribs and other secondary members |
Fillet weld with groove(CJP and PJP) | K=t/4 and K≤10mm | for most of the steel structure buildings |
K=t/2 and K≤10mm | important members(crane beams or connection between web plates and
flange plates of similar members) |
Note: 1) t——thinner weld member thickness
2) For concave fillet welds, the actual measured value is required to
be 1-3mm higher than the fillet weld foot size specified in the
above table.(because what actual measured is not the fillet weld
size, it is larger than the fillet weld size)
3) If it is specifically marked on the drawing or technical document
for the fillet weld size, we will strictly follow it.
For the secondary members which are free of force and only serves
for strengthening, the fillet weld size could refer to the
following chart:
Minimum fillet weld size could be valued per the following chart:
Parent metal thickness(t)(mm) | Minimum fillet weld size |
t≤6 | 3(minimum value being 5 for crane beam) |
6＜t≤12 | 5 |
12＜t≤20 | 6 |
t＞20 | 8 |
