Customer Case Study
An Australian client purchased powder-coated, pre-galvanized steel square tubes. Upon initial receipt, they conducted adhesion tests between the powder coating and the square tube surface, observing lower adhesion values than requested.
We initiated consecutive engineering meetings to analyze and resolve the issue. By polishing the square tube surfaces and executing specialized thermal conditioning inside the heating furnace, we continuously verified performance alongside the client. Following extensive optimization, the product successfully met the client's specifications, leading to a consistent, high-volume monthly procurement arrangement.
