Australia Prefabricated Steel Structures Workshop Modern Type Truss
Roof
Project description:
This heavy industrial steel structure workshop is used as a
maintain workshop. The size of this workshop is 80*50*10m (L*W*H),
With 2pcs 10ton crane, 4pcs 5 tons crane. 75mm EPS cladding system.
Steel truss girder, steel structure weight is 300 tons.This project
come from a australian steel structure manufacturer. their quality
requests is very high. Total workshop area is 4000 sqms, Removing
column is the unique feature. You see there many removing columns,
This is design not make the trimming joist (chinese standard). But
make the central big truss to make all the workshop as a whole.

Paint:
Within 2 hours after blasting the steel member mustbe painted to
gurantee the painting quality. this project we use EPOXY ZINC RICH
PRIMER, TWICE PAINT 80 um. After primer paint, we make Epoxy Mio
Barrior Paint 40 paint, that paint will ensure all the components
will be not rust during long time shipment on the sea.
Inspection:
We make the Ultrasonic Testing In-house, Take record and make
report in-house. After we check the components that will be ok.
then we ask clients' Inspector come to our factory to check if the
quality will be good to loading.
Packing And Loading:
All the structure components, panels,bolts and sort of accessories
will bewell packed with standard package suitable ocean
transportation and loaded into 40’HQ.
The following questions we need to know before making the price if
you need us to design.
Just feel free to fill the form based on what you know.
| 1 | Location (where will be built?) | _____country, area |
| 2 | Size: length*width*height | _____mm*_____mm*_____mm |
| 3 | wind load (max. wind speed) | _____kn/m2, _____km/h, _____m/s |
| 4 | snow load (max. snow height) | _____kn/m2, _____mm |
| 5 | anti-earthquake | _____level |
| 6 | brickwall needed or not | If yes, 1.2m high or 1.5m high |
| 7 | thermal insulation | If yes, EPS, fiberglass wool, rockwool, PU sandwich panels will be
suggested; . if not, the metal steel sheets will be ok. The cost of
the latter will be much
lower than that of the former |
| 8 | door quantity & size | _____units, _____(width)mm*_____(height)mm |
| 9 | window quanity & size | _____units, _____(width)mm*_____(height)mm |
| 10 | crane needed or not | If yes, _____units, max. lifting weight____tons; max. lifting
