Large Span Prefabricated Steel Structure Construction With
Fire-retardant coating
General
The large span steel structure building is usually a key criterion
for considering the high-tech level of a country’s architecture,
and it is also a representative of the development trend of a
country’s civilized behavior. All parts of the world attach great
importance to the theoretical basic research and practical
activities of large-span indoor space architecture. The integration
of structural form and architectural art space can best reflect the
appeal of structural art aesthetics, and it has also aroused the
imagination of architects.
We disign the drawing, fabricate all the steel columns, beams,
purlin, ect, install the steel structure and panel,
window&doors for our client.
The role of fire retardant coatings in steel structures:
1. Extend the fire protection time of the steel structure: apply
fire-resistant paint on its surface. In case of fire, the
non-combustibility and low thermal conductivity of the coating form
a fire-resistant and heat-insulating protective layer to increase
the fire resistance limit of the product. After the fireproof
coating of the product is sprayed on the surface of the steel
component, it relies on the non-combustibility and low thermal
conductivity of the coating itself to form a fire-resistant and
heat-insulating protective layer in case of fire, which effectively
increases the fire resistance limit of the product.
2. Make the steel structure healthy and environmentally friendly:
Health and environmental protection are the eternal theme in that
field. It does not corrode steel, does not chemically react with
any anti-corrosion primer, has no irritating odor, and has light
coating quality (the structural load weight is relatively low).
Light), the unit coating area is large, it does not produce smoke
or release harmful gases when exposed to fire, and it is not
harmful to the human body.

How to quote
The following question we need to know before making the price.
Just feel free to fill 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
height _____m |
