Frequently Asked Questions
What size T-slot extrusion for beginners?
Start with 2020 or 3030 profiles. Lightweight, affordable, perfect for prototypes under 50kg loads.
T-slot vs V-slot: Which better?
T-slot for static frames; V-slot excels in linear motion with V-wheels. Hybrid builds combine both.
Best suppliers for T-slots 2026?
80/20 Inc., Misumi, or Amazon for kits. Check metric/imperial compatibility and cut-to-length services.
Can T-slots support heavy machinery?
Yes, 4040+ series with gussets handle 1000kg+. Calculate deflection using online span calculators.
