*Spiral Bundle: Extrusions are stacked and tightly wrapped with a stretch film for finish protection.
*Shrink Sleeve: Extrusions are individually covered with a heat shrink film that tightly adheres to the profile for finish protection.
*Interleave / Kraft: Extrusions are serpentine interleaved with PEP and Kraft for finish protection.
*Paper Layer / Box: Extrusions are layered, separated by paper and boxed for finish protection.
*Box: Extrusions are placed in custom cardboard boxes for finish protection.
*Custom Crate: Extrusions can be placed in a custom wooden shipping crate for further protection.
The 6000 series, which incorporates magnesium and silicon, provide good extrudability, strength, corrosion resistance, formability and machinability -- which explains why it’s also ZJD’s alloy of choice for all our aluminum extrusions.
We accept many file formats such as DXF, DWG and IGES.
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.
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 weather resistance.
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.
