? ? Steel&panels&sheets steel structure frame and roof panels/wall panels/accessories almost like them:

? ? Welded steel frame Welded steel structure frame/warehouse/workshop/Prefabricated house/storage/Meatal shed must have strict process and good qulity , than it is safe and long life .
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.

Attached: welding process parameters

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.
