Aluminium extrusion do’s and don’ts (checklist)

Here’s a multi-point checklist to help you get the best from your aluminium extrusion supplier. Choose wisely.

Do provide drawings and CAD files with the right technical information. If you can’t do CAD, ensure they can.

Do understand your end application and if there is a general assembly drawing it will help them understand it too; NDA’s permitting.

Do check if they can cut and machine the extrusion for you (if required) and if it’s machined do they have state of the art measuring equipment to ensure compliance

Do your homework. Get recommendations within the industry. Exercise caution when vetting suppliers via the Internet you can appear to be anything on a website. 

Do know how the extrusion is going to be used its mechanical and aesthetic requirements.

Do indicate the visible surfaces (or if none if it isn’t on display).

Don’t select more than 3-4 specialist companies to provide a response.

Don’t judge companies by the speed of their initial response.

Don’t be unrealistic when it comes to finding the balance between having it quickly, inexpensively or at a high quality. You can generally only have any two of these.

Don’t forget to advise drop dates and locations and importantly packing so logistics and handling can be factored into the project timelines.

Don’t buy only on price it always costs more in the long run.
