Engineering Support - Aluminum Profile Specifications

The collective information below for our T-Slot framing profiles are the same tools our engineers use when evaluating stress and vibtations, and other material specifications for a given project. Going through these evaluations can be a confusing process, so please reach out to our engineering group anytime for assistance. Down-load ready catalog pdf pages containing all of this information are at the bottom of this page and each product page.

Additionally, on-line resource links (with CAD drawings and online calculation tools) are also available and which are located, by part number, at the bottom of each profiles page. For example: the online resources link for our SP3450N 28mm x 200mm framing profile will be located at the bottom of the 28mm framing profile page.

Aluminum Framing - Profile Tolerances

Production related deviations in regards to straightness, flatness and twist but also outside and T-Slot dimensions are in accordance with the standard DIN EN 12020: 9001 (part 2).

Please Note – Paletti USA stocks the natural anodized finish in all sizes, the black anodized finish in select sizes. Other finish colors or un-finished framing profiles are available via special order.

Aluminum Framing - Supplied Lengths

Per DIN EN 12020 (part 2) - Requirements for exact extrusion lengths should be communicated with your order. Standard 3 m or 6 m length extrusions may be slightly longer due to production related requirements.

Aluminum Framing – NV Profile T-Slot

The NV t-slot is not pre-tensioned. The NV profile range has been designed for use with gauge plates and linear bearings that require the profile surface to be flat. For example: Jigs, fixtures, and special purpose machines.

Aluminum Framing – T-Slot Dimension Tolerances

The standard, semi, and superlight series framing profiles possess a standardised T-Slot shape. This guarantees that all fasteners and accessories can be utilised with the different profile series and sizes. T-Slot dimensions for 1” profiles are the same as our 20mm Series. T-Slot dimensions for 1 ½” profiles are the same as our 40mm Series. T-Slot dimensions on our 45mm and 50mm profiles are shown on their respective pages.

Aluminum Framing – Center-Hole Dimension Tolerances

The center-hole bore of the T-Slot framing profiles can be opened up according to the table. Profiles of the series superlight (40 mm) and midi (30 mm), however, may not be opened up due to the wall section around the center hole.

Aluminum Framing – Drilling Position Tolerances

The drilling position tolerance is dependent upon the number of the T-Slot center-hole bores and the contour of the profile.

Please Note that in all the above stress / deflection calculation formulas the following definitions apply where:

F = load (N)

L = profile length (mm)

I = Inertia Moment (cm4)

E = Elasticity Modulus (N/mm2) EAI = 70,000 N/mm2

The following formula should be used when calculating “Control of the Deflection” where:

S = deflection (N/mm2)

Mb = maximum bending [N/mm]

W = resistive moment (cm3)
