Produktbeschreibung

Aerospace-Grade Aluminum Construction - These joining plates are crafted from high-strength aluminum alloy, ensuring exceptional durability and oxidation protection for long-term structural integrity in industrial and DIY applications. Accurate 2-Hole Vertical Joint Design - Joining plates feature optimized hole placement and oxidation-finished exteriors, enabling smooth vertical connections between profiles without hazardous edges or hand injuries during installation. Versatile-Size Compatibility - With three types (2020/3030/4040) covering 40mm-80mm lengths, these connectors provide universal solutions for linear extensions and overlapping joints in aluminum framing systems across construction and workshop projects. Time-Efficient Installation System - Pre-drilled holes and smooth exteriors allow hand tightening without tools and infinite positioning flexibility, reducing assembly time by 50% compared to traditional welding methods. Structural Integrity Assurance - Each plate undergoes rigorous pressure testing to support heavy loads without deformation, backed by ISO-certified manufacturing standards for consistent commercial and residential use.
