and workshops
Steel structure warehouse
Steel structures are widely used in factories, warehouses, offices,
shopping malls, schools, hospitals, community buildings, stadiums,
football fields, etc. The basic material of the steel structure is
high quality Q235/Q345 steel. The seismic conditions are 8 degrees
seismic conditions, climate conditions are -20°C-45°C, snow load is
100 Kg /m⊃2; wind speed is 150 Km / h.

36m, and there is no intermediate column.
2. Low cost: According to customer requirements, the unit price is
between US$30 and US$75/square meter FOB.
3. Fast construction and easy installation

1. Structural system:
1) Primary and secondary structural materials: commonly used
Chinese national standard building steels are Q355B and Q235B;
according to the section processing technology, they are divided
into hot-rolled steel and welded steel. Surface anti-corrosion
treatment, mainly including painting or galvanizing, and larger
welding. Components should be painted, small components and
cold-formed thin-walled steel components should be galvanized.
According to local fire protection requirements, steel columns and
roof beams should be coated with fire-resistant paint.
Roof purlins and fence beams: The roof purlins and fence beams are
cold-formed thin-walled steel, and their structural forms can be
divided into C-shaped simply supported beam mode and Z-shaped
continuous beam mode.
2. Closed system:
The roof and wall panels mainly use single-layer color-coated
corrugated steel plates and sandwich panels. The insulation
material is made of glass fiber insulation cotton; the roof
lighting belt is made of PVC transparent lighting board.
1) Single-layer color coated corrugated steel sheet:
(1) Substrate: Al-Zn coated substrate with thickness of 0.3, 0.45,
0.5 and 0.60 mm. Galvalume coated sheets are used in buildings in
extreme environments. They have high corrosion and weather
resistance, with a service life of more than 20 years.
(2) Coating: Polyester coating (PE): good adhesion, wide
application range, medium resistance to chemical media, 7-10 years
of service life; silicon modified polyester (SMP): coating film has
good hardness , Wear resistance, heat resistance and durability,
limited gloss retention and flexibility, and a service life of
10-15 years;
High weather resistance polyester (HDP): excellent UV resistance,
high durability and 10 to 12 years of service life;
Polyvinylidene fluoride (PVDF): good moldability, excellent outdoor
durability and solvent resistance, but the color is limited, the
cost is high, and the service life is 20-25 years. 2) Glass fiber
insulation cotton commonly used glass fiber insulation cotton has a
bulk density of 12K, which has good heat insulation, sound
absorption and corrosion resistance. It is a non-combustible
material (A1 grade) with low moisture absorption rate. 3) The color
steel plate sandwich panel consists of two single-layer color steel
plates and a middle-layer polymer insulation core (including EPS
sandwich panels, rock wool sandwich panels, glass wool sandwich
panels and polyurethane (PU) sandwich panels) The thickness is
usually 50, 75, 100mm. The single-layer color steel sheet is as
described above.
3. Door and window system: Door: Commonly used doors include side-hung doors, sliding doors
and rolling doors.
4. Ventilation system:
Steel structure warehouses and workshops have a large construction
area and have fire hazards. Because of the depth of the workshop,
it is difficult to remove the smoke by opening the outer wall. It
is necessary to consider setting up mechanical exhaust facilities
or natural exhaust in the middle of the factory.
(1) Skylight: Its main functions include ventilation, lighting and
smoke exhaust.
