The Edge

 Competitive Prices Our production capacity (approximately 20000 metric tons annually) together with effective

 and economic 

 engineering and manufacturing methods enable us to offer the most competitive prices in the industry.

Fast Quotations

 Quotations for simple buildings can be submitted quickly due to vast experience of our staff and the advanced 

software we use.

Fast Delivery 

 (1)We are able to design, detail, fabricate and supply simple buildings in approximately 4 weeks. 
 (2)Most of our buildings are delivered and erected within 8 weeks (this relies on various factors such as stock 

position, weather etc).
Site Supervision 

  (1)A site supervisor is always present at site to ensure that work is being carried out satisfactorily.
  (2)Any problems that arise are quickly dealt with to minimise any delays. 
  (3)Safety on site is also made a priority.

We often use Ultrasonic detector ,X-ray detector , Paint film thickness gauge to check steel frame .

1. Strictly control the welding position of the relative position of size , welding pass behind the prospective;

2. Reasonablly selection of welding parameters and order to prevent crack;

3. Electrode required drying, welding area need to clean up, welding process, together with the appropriate welding current, decrease of welding speed, gas completely escape , prevent the formation of weld porosity;

4. When continuously multi-layer welding, each weld layer after cleaning, prevent the formation of slag;

5. Selection for current, avoid arc pull too long, control electrode angle and arc method, avoid the generation of undercut.

Fixed packing, loading, transportation, unloading the matters needing attention:

(1) The lifting large there must be a person responsible for the use of fixture, suitable, strictly abide by the

rules of lifting, to prevent the occurrence of vibration, impact, deformation or damage, fall in the hoisting process.

(2) At the time of loading, there must be a special supervision, check car number and packing, the car pile

up securely, and to increase the necessary binding component loosening, prevent the loss.

(3) Remained stable in the transport process, the vehicle at the time of shipment, on the long, wide, high object transport, must be trained pilots, escort personnel responsible for, and mark is arranged on a vehicle.

(4) No rough handling, loading and unloading personnel handling, weight, size should be familiar with the components, and check the horse sling, rigging, prevent accidents.

(5) The member to the construction site, timely organization of unloading, stacking area.

(6) The crawler crane carrying member, should pay attention to the surrounding terrain, air condition, prevent the crawler crane overturning and component collision.

1.Dimension :Length , width, height, eave height , roof pitch .

2.Doors and windows :dimension , quantity , where to put them.

3.Local climate : Wind speed , snow load ,etc

4.insulation material :sandwich panel or steel sheet

5.Crane beam :Do you need crane beam &tons? inside the steel structure or outside ?

6.Is there any materials that are not allowed to imported into the country where the structure is planning to use ?

7.What is the founctions of the workshop? we must consider the wind and lighting inside.
