Innovative No-Weld Design for Seamless Anodizing
– Traditional double-arm aluminium poles are welded at the joint, but welding creates discoloration after anodizing, making it unsuitable for the client’s clear anodized finish requirement.
– Our Solution:
– Developed an internal structural plate system to connect the arms mechanically (via bolts) instead of welding.
– Custom precision tooling was engineered to ensure seamless alignment of the arms with no visible gaps.
– Required sub-millimeter accuracy in cutting and assembly—achieved through specialized CNC machining.
Corrosion Resistance & Longevity
– Qatar’s coastal environment demanded extreme corrosion resistance with a 30-year surface guarantee.
– Enhanced Anodizing Process:
– 25μm-thick anodized layer (far exceeding standard 15–20μm) for maximum durability.
– AA-M12-C22-A31 (Class I) anodizing compliant with ASTM B580 for harsh climates.
Result
– A first-of-its-kind, weld-free aluminium pole with:
– Flawless clear anodized finish (no discoloration).
– Structural integrity maintained through bolted internal reinforcement.
– 30-year corrosion warranty, meeting Qatar’s demanding coastal conditions.
Key Highlights:
Breakthrough Engineering – Eliminated welding for perfect anodizing.
Precision Manufacturing – Custom tooling for seamless assembly.
Unmatched Durability – 25μm anodizing for 30-year performance.
