3030 vs 4040 Aluminium Profile: A Decision With Numbers
Section comparison · 30 against 40 3030 vs 4040 Aluminium Profile: A Decision With Numbers The usual answer is that a 4040 is “more than twice as strong”. It is 2.6 times as stiff, 1.35 times as heavy, and it buys bending stiffness at roughly half the cost per unit. It also commits you to […]
Aluminium Extrusion Tolerances: What to Write, and How to Inspect
Metrology · incoming inspection Aluminium Extrusion Tolerances: What to Write, and How to Inspect Most tolerance articles tell you that a bigger profile has a bigger tolerance and that you should not ask for more accuracy than you need. None of them give you the numbers. Here are the EN 755-9 tables you actually inspect […]
Standard vs Custom Aluminium Extrusion: The Break-Even Calculation
Sourcing economics · tooling Standard vs Custom Aluminium Extrusion: The Break-Even Calculation Every guide says a custom die costs $1,500 to $5,000 and a standard profile ships in 48 hours. None of them tell you the volume at which the die pays for itself — and that number is the only one that decides the […]
Aluminium Profile Standard Sizes: How the Series Matrix Actually Works
Standard sizes · series matrix Aluminium Profile Standard Sizes: How the Series Matrix Actually Works A 4040 is not one product. The 30 series and the 40 series share the same slot on most European grids. And “standard size” is not a specification. Here is the full T-slot series matrix — slot mouth, channel, centre […]

How to Choose the Right 4040 T-Slot Aluminium Profile for Industrial Applications
4040 selection How to Choose the Right 4040 T-Slot Aluminium Profile for Industrial Applications 40 × 40 mm is the default section in industrial framing. The useful question is not whether it is strong enough — it is what stepping up or down a series actually buys you, and what it costs across the whole […]
How to Choose the Right T-Slot Aluminium Profile for Your Project
Project planning How to Choose the Right T-Slot Aluminium Profile for Your Project The right section for a one-off frame is rarely the right section for a hundred. Here is how the decision changes with project type and quantity — and the four points at which a project quietly loses money. 11 min readPrototype vs […]

Size selection How to Choose the Right Aluminium Profile Size for Industrial Frames Size is the last lever, not the first. Here is the five-step calculation that turns a load, a span and a deflection budget into one section number — plus the span at which strength stops governing and stiffness takes over. 12 min […]

Metric vs Imperial T-Slot Profiles: How to Test Compatibility Before You Order
Two 40 mm profiles can look identical and still refuse to share a fastener. The four dimensions that decide compatibility, the pitch error arithmetic, and how to write the requirement into a purchase order.
Aluminum vs Steel Machine Frames: Choose by Deflection, Not by Strength
Every aluminium-versus-steel comparison starts with strength, and every one of them answers the wrong question. A machine frame fails by moving too much, not by yielding. Here is the stiffness arithmetic, with worked numbers you can check.
