Aluminum Extrusion Design and Sourcing Resources
Use these resources to prepare drawings, select aluminum alloys and finishes, understand secondary processing, and submit a more complete request for quotation. For project-specific advice, send your drawing to our engineering team.
Profile Design
Wall thickness, corner radii, cavities, tolerances and machining allowances affect extrusion feasibility, tooling and total cost.
Alloys and Tempers
Compare strength, machinability, corrosion resistance and finishing requirements when selecting an alloy for your application.
Surface Finishing
Review anodizing, powder coating, electrophoresis and wood-grain options according to appearance, durability and environment.
RFQ Preparation
Include drawings, alloy, finish, part length, quantity, critical tolerances, secondary processing and delivery requirements.
