First: we produced the standard section adopts the international advanced robotic welding process,

welding is not any ordinary direct wire electrode manual welding, plus dioxide gas shielded arc welding

technology to ensure standard section will not have weld slag residues.

Second: Our products are different from other manufacturers that produce only the main frame,

and then from all over the package, patchwork. Most accessories are independent production company,

tailored for the main product. Despite an increase in costs, but the service has been allowing users to protect!
