QUALITY

Being a customer focused company, Selaco takes its pride to supply the aluminium profiles in good quality. From billet to extruded section, stringent quality control take place to ensure conformance to specification.

Equipment	Inspection Purpose
Spectrometer	To check the chemical composition of the billet/ extrusion
Pin Tester(Reduce Pressure Test)	To check the gas content in the billet
Pyrometer	To check the temperature of the profile during extrusion
Non-destrustive Hardness Tester	To check the hardness of aluminium profile
Profile Projector	To determine the dimension of the profile
Tensile Testing Machine	To determine the tensile strength of the profile

Tensile Testing Machine	Spectrometer	Profile Projector

To ensure that the extruded section can meet the world standard compliance, Selaco use the international standard for reference to control the quality of the aluminium profiles.
