A: Workshop crane: ≥ 25tons, thickness of main metal structure part: ≥ 10MM

Q: Whit is the material for the steel structure workshop, such as main structure part, secondary part, purlin?
A: Main steel structure part is Q345; Secondary steel structure part is Q235B; Purlin is Q235orgalvanized C type or Z type steel.

Q, what is the model and slope for this steel structure building?

A, double pitch roof with middle column, 20% slope.

Q, what is the material for the roof and wall in this steel structure building?

A, wall is glasswool sandwich panel, roof is glasswool sandwich panel. Thickness is 50mm.

Q, what type door and window in this steel structure building?

A, door is slding door, window is Aluminium alloy window.

2nd, characteristic of heavy steel structure workshop

Q, what is the type of the steel structure workshop
A, heavy steel structure workshop

Q, what is the usage for the heavy steel structure?

A, usually for high-rise buildings, high-rise buildings and large span stadium, exhibition hall, etc, civil construction, and power plants, chemical plants, power plants, Bridges, steel structure, petrochemical factory facilities, water conservancy, shipyards, ports and other buildings.

Q, what is the difference between light steel structure and heavy steel structure workshop?

A, There is no big difference between light steel structure and heavy steel structure workshop. It is can be judged by the following information

1, workshop crane lifting weight: Greater than or equal to 25 tons, can be thought of as heavy steel structure.
2, Steel weight of per square meter: Greater than or equal to 50 kg/square meters, can be regarded as heavy steel structure.
3, the main components: Steel plate thickness is greater than or equal to 10 mm, thickness for light steel structure is less.

Q: Steel structure factory building fire prevention performance?
A: Mainly adopts fireproof coatings, foam fire retardant paint, and fire protection measures such as casing.

Q: The steel structure factory building common economic anticorrosive measures?

A, 1, hot dip galvanized, hot dip galvanized after rust removal of steel structure components in 600 degree centigrade high temperature melting zinc liquid, make the zinc layer adhered on the surface of the component, the advantage of this approach is durable life, long-term anti-corrosion, high industrialization degree, stable quality
2, coating: Coating method is not better than long-term anticorrosion method, but the fixed number of year of the fluorine carbon coating corrosion resistance can be up to 50 years, it is been used widely in indoor structure or for ease maintenance outdoor steel structure, with lower cost, but when used in outdoor it requires constant maintenance.
3, Cathodic protection, widely used in the underwater or underground structure

3th part

Q: The process of sintering plant components, what are the main control points of quality control?
A: Raw material inspection, groove, bedding, filling, double wire, wire submerged arc welding, flame correction, second set of processes, such as ultrasonic inspection all the process.

4 th part: Technology services
1, the customer can provide drawings, we processed based on the drawings.
2, We can design according to customer's requirements, based on the information customer offered.

5th part, transport
