Ladies and gentlemen,
Pls. attention,
steel structure building is one kind of product which can be design as per every proples' different need.
so, if you found that follows example pictures is not as same as your want, even it is very different.
do not worried,
no matter which kind of building you need,
bigger, smaller or multi-storey, just tell me the data or drawing of building what you need.
we will make the exact design, quotation and rendering for you as soon as we can.
(our factory have more than 30 years experience on steel structure and more than 20 years on steel structure building, and our cheif engineer have about 20 years experience on building. )
primary data of building for making design and quotation:
1. length, width, eave height, top height
2. location and size of door and window.
3. do you need skylighting belt and ventilator?
Product Description:
The advantage of our building:
(1) Enough strong
it can resist 70m/s hurricane and G10 seismic intensity and protect your life and property. Furthermore, we also can design and build a stronger building according to your required.
(2) No water-seepage problem.
through the research and test by our technical team and construction team, we designed a whole reasonable and effective method of flashing plate and over-lapped of steel sheet, include(1. flashing plate on the roof, wall, bridge, eave, gutter and frame of window and door, 2. Joints between steel sheets and sky lighting belts, 3. Waterproof of nails ), with accuracy process and superior quality closure strips, we successfully reduce the leakage place from 1/1000 to 1/2500 place/sqm.
(3) High-performance heat insulation
(4) Excellent Anti-corrosion and long life
shot blasting and 4 layers paint(90micron)/1 layer hot deep galvanized (80-200g/sqm) will provide our building 25-50 years life.
(5) Good air permeability and more natural lighting
natural roof turbine ventilators, bridge ventilators, Roof sky lighting belts, Wool sky lighting belts and varies of windows, they will bring us more fresh air and natural lighting.
(6) Quick installation
12 workers can assemble 1000sqm within 20 days.
(7) 100% recovery.
1. Design
we can design the building according to your requirements.
2. Produce every compoents of the building
as follows are our production process and quality check
(1) purchasing of raw material:
performance of all steel plates must be in accordance with Q345 or Q235 required in country standards, no sandwich flaws, no dopants and no crack.
| Steel No. | Grade | Physical Property |
| Yield Point (N/mm2) | Tensile Strength (N/mm2) |
| Q235 | B | 235 | 375-500 |
| Q345 | B | 345 | 470-630 |
| Steel No. | Grade | Chemical Constituent (%) |
| C | Mn | Si | S | P |
| Q235 | B | 0.12-0.20 | 0.30-0.70 | <=0.3 | <=0.045 | <=0.045 |
| Q345 | B | <=0.20 | 1.00-1.60 | <=0.55 | <=0.040 | <=0.040 |
(2) Plate cut:
flame cutting: notch is slippy and straight, it will be a good start for welding.
(3) Assemblage:
(4) Automatic welding for H steel
automatic arc-submerging welding: full weld, and check weld joint very carefully in order that there is no crack, no unjoint, no lack of penetration, no slag inclusion and no blowhole.
(5) Straightening.
with Mmchanical straightening and flame straightening, we will make every plate of H steel straight in both of horizontal and vertical thus prevent crooked steel plate from the reduction in yield strength of H steel.
(6) Holes Drilling
accuracy position of hole will be helpful of quick installation and fastness
(7) Manual welding for stiffener and connecting plate.
(8) Shot blasting:
grade: Sa2-2.5
rust will fall off paints, so better blast cleaned, better paints.
(9) Application of paints:
two layers primer paints and two layers surface paints, total thickness of paints is 90 micron.
painted will be completed within 4 hours after blast cleaned in order to prevent from rusting again. In addition, there will be anti-fire paints if required.
(10) Acid cleaned and hot deep galvanized
in usually, for some building , in order to protect the service life of these building which are near the sea or established in strong corrosion place, we will use the acid cleaned and hot deep galvanized.
thickness of galvanized: 80-200g/sqm
(11) Quality check
Professional is our best service.
Looking forward to your inquiries !
