T‑slot and V‑slot aluminium profiles share the same modular idea but differ in groove shape and hardware. T‑slot uses a “T” groove that clamps T‑nuts and brackets for rigid frames and guarding. V‑slot has a V‑shaped track that doubles as a linear guide for V‑wheels, ideal for motion systems and compact machines.
Aluminium profiles don’t have one “standard size.” Most are custom cross‑sections, but common ranges are 10–200 mm wide, 1.0–5.0 mm wall thickness, and standard lengths around 6 m (cut‑to‑size available). T‑slot series often come in 20×20, 30×30, 40×40, 45×45, 60×60, while large presses enable sections up to roughly 480 mm.
An aluminium profile has no single fixed price. Total cost is driven by alloy and temper, weight per meter (kg/m) determined by the cross‑section, finish (anodized, powder, PVDF), fabrication and tolerance, thermal break components, MOQ and die/tooling, logistics, and the market aluminium price.
