Q1: What are the advantages of using the 6000 series of alloys in aluminum extrusions?
 

A: The 6000 series, which incorporates magnesium and silicon, provide good extrudability, strength, corrosion      resistance,formability and machinability- which explains why it’s also TRUST’s alloy of choice for all our 

     aluminum extrusions.

Q2: If I wish to send an electronic drawing to you, what types of files can you accept? 
 

A: We accept many file formats such as DXF, DWG and IGES.

Q3: Why do extrusion companies always ask me to sign off on a drawing before they can order 

tooling if I’ve already provided a drawing? 
 

A: Oftentimes, we find a few key dimensions that are missing from the original drawing that need to be clearly

    identified. 

    Other times, we have taken exception to a tolerance, dimension, alloy,note, surface condition, etc. It’s just 

    our way of  documenting exactly what we have agreed upon

Q4: What is the difference between anodized and mill finished? 
 

A: Mill is the raw state of aluminum as extruded - no surface treatment. Anodized (also known as Satin  Clear or Clear Anodized) is an electrolytic process. This process increases corrosion resistance and  weatherresistance

Q5: What About Anodizer Rack Marks?

A: Electrical contact must be made to each part to be anodized. The more electrical current required, the

    greater the electrical contact. The size of the contact therefore depends on the anodizing process and

    the size of the part being anodized.
