2) In order to give you an exactly quotation and drawings, please let us know length, width, eave height and local weather. We will quote for you promptly.
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.
