FAQ

Call us if you have any further questions! Our Extrudinaire will be pleased to assist you!

Ask us anything:

Q. Do you do custom extrusions?
A. Sorry, we are not a manufacturer of extruded Aluminum. We have over 100 styles to choose from, 55 Fractional profiles & 46 Metric profiles.

Q. Do you have a minimum order?
A. No.

Q. Can profiles be welded?
A. Yes. We strongly advise you do so in a well ventilated area due to toxic fumes generated by the profiles anodized finish.

Q. Can profiles be cut with a table saw?
A. Yes. A saw cut finish supplied by 80/20 will have a cut tolerance of +/- 0.015” and have a square tolerance of 0.002” per inch maximum. Be sure to use some type of coolant (vegetable-oil based is best).

Q. What saw blade do you recommend when cutting your profiles?
A. High speed steel blade with carbide tips. Double or triple chip (number of different designs of tips on each blade – the more designs on the blade, the more stable the cut will be which means a better finish on the cut). 60-72 teeth –blade width .375" .

Q. Will the anodize finish on Aluminum profiles be damaged if the profiles are bent?
A. Yes. If you bend the profiles cracks in the anodizing will appear at the bend.

Q. What is the alloy used in your T-Slotted Aluminum extrusions?
A. We use 6105-T5 Aluminum alloy because of its higher ultimate and yield tensile strength. 6105-T5 Technical Data Sheet.

Q. What is the yield strength of this material?
A. 80/20's T-Slotted Aluminum profiles have a yield strength of 35,000 lbs./ sq. in. minimum.

Q. How much weight can your extrusions support?
A. In most applications load requirements can be met by selecting the proper profile(s), fastening method(s), and design details. 80/20's Deflection CalculatorX™, which can be downloaded from the Tech Tool Kit, will assist you in making these decisions. Call us if you have any application-specific questions.

Q. What is the maximum load weight for roller wheels?
A. Suggested maximum is 50 Lbs. each for part numbers 2281, 2282 & 2290, and 65 Lbs. Part number 2280.

Q. What does 80/20 recommend for addition lubricant on UHMW bearings?
A. Silicone spray works without damaging the material.

Q. What is the recommend service temperature for UHMW?
A. UHMW offers continuous support up to 163 degrees Fahrenheit.

Q. What are the recommended solutions when the bearing does not slide smoothly over the profile?
A. Tap the housing with a rubber mallet, or lubricate the UHMW bearing.

Q. How many different sizes of T-slotted profiles do you offer?
A. 55 Fractional profiles & 46 Metric profiles.

Q. Do you offer extrusions in different colors?
A. T-slotted extrusions come with a standard clear anodize. All extrusions can be supplied in custom anodized colours for an additional charge. Black is very popular, many extrusions are stocked in black: Black FAQ page. Custom colour anodized orders will be quoted upon request.

Q. What is the difference between the 10 Series and 15 Series T-slotted extrusions?
A. 10 Series extrusions are designed on 1/2" and 1" dimensions. The center point is 1/2" from the edge of the extrusion, with a 1" center to center measurement. 15 Series extrusions are designed on 3/4" and 1.5" dimensions. The center point is 3/4" from the edge of the extrusion, with a 1.5" center to center measurement.

Q. Do any connections have a locking mechanism so that the connections hold tight even when subjected to movement or vibrations?
A. The locking mechanism is in the design of the T-slotted profile. The T-slot flange declines two degrees in towards the center of these profiles. This "Drop Lock Feature" acts as a lock washer in that it spring loads the fastener as it is tightened.

Q. What are your stock lengths of extrusions?
A. While not all profiles are available in all lengths, most Fractional T-slotted extrusions are available in 145" and 242" stock lengths. Most Metric T-slotted extrusions are available in 4M and 6M stock lengths. Consult the current 80/20 Catalog for profile stock length specifics. NOTE: We also supply 'cut to length' as a regular service.

Q. How much weight will linear bearings support if they are attached to the underside of a beam?
A. We strongly suggest that linear bearings NOT be used in this configuration.

Q. : Are the Tap Extrusion Ends services (ex. 7060) for one or both ends of the extrusion?
A. Tap extrusion ends services are for one end. You can specify different tap sizes at opposite ends of the same extrusion.

Q. Can I buy 80/20 products directly from the factory?
A. 80/20 has developed a network of value added distributors from which their entire product line may be purchased. Rocky Mountain is the 'authorized' distributor for Western Canada.

Q. I just need a small piece, do you keep any stock?
A. We have some of the most popular fractional profiles in stock, 1010, 1020, 1030, 1515, 1515-LITE, 1530, 1545 and 3030! Call for availability.

Q. : I was looking at some of the 80/20 Aluminum online, what’s the best way to get a quote?
A. Send an email or call us.

Q. We are a new start-up in forming and currently we are in the R&D stage looking for a replacement for our current custom Aluminum extrusion rail. Where are you located?
A. In the suburbs of Vancouver, BC – we ship anywhere.

Q. : I'm working on a new design and decided to use T-Slot Aluminum extrusion as the frame material due to its modular nature. I've never sent out a 3D sketch so I'm going to send a zipped copy of the Solid Works assembly file. Is that okay?
A. Yes, send us any drawing file or fax us a sketch - basic or sophisticated we work with it all.

Q. We are building a test station with T-Slotted frame. We are in need of several fittings, Aluminum brackets and more T-Slotted Aluminum. We don't have a shipping company, can you help?
A. Yes we can handle all your shipping needs, plus we pass along our volume discount - ask us for a shipping quote direct from factory or with our monthly stock orders.

Q. I’m looking for Aluminum T-Slot for building robotics, is 80/20 T-Slot suitable?
A. It certainly is – 80/20 is a popular choice for robotics.
