HG081 20×20 T-Slot V-Slot Aluminium Profile – 500-word English Introduction   The HG081 20×20 T-Slot V-Slot Aluminium Profile is a precision-extruded structural framing component engineered for makers, engineers, and industrial designers who demand modularity without sacrificing strength. Measuring exactly 20 mm × 20 mm, the profile combines two popular mounting standards—T-Slot and V-Slot—into one compact rail, enabling both linear motion applications and versatile 90-degree connections. Manufactured from 6063-T5 aluminium alloy, it offers an excellent balance of corrosion resistance, rigidity, and machinability while keeping overall weight low at approximately 0.97 kg per meter.   The signature feature of the HG081 series is its dual-function groove. The outer lip forms a conventional 6 mm T-slot that accepts standard M5 T-nuts, bolts, and bracketry, allowing rapid assembly of frames, enclosures, or robotic chassis. The inner groove is precision-milled into a 5° V-slot that acts as…
