Aluminum extrusion for bridge construction - KamorkasOa - 05-21-2018 Aluminum extrusion is one of the best structural materials for the building of bridges and pontoons, especially for pontoon, aluminum extrusion is the preferred material, because aluminum extrusion has many advantages.

The strength performance of series 6xxx aluminum alloy is comparable with low-carbon steel, so its specific tenacity and specific stiffness are far more than that of steel. 2.Strong corrosion resistance Rainwater, seawater, salt form road and mud does not corrode the aluminum bridge, especially for the series 5xxx aluminum alloy, we no need to painting and maintenance routine after construction. Smithfield Street Bridge is an aluminum bridge, it’s been 84 years that he serve people and never fading charms. 3. Good toughness Has a good expand ability of anti-fatigue crack, no rheotropic embrittlement. The strength and plasticity of aluminum alloy will enhance when temperature drops, 90% of steel has rheotropic embrittlement, so the aluminum alloy is the best material for bridge in alpine region. 4.Good extrudability A good extrudability is very important for bridge. The a good extrudability material is able to produce what designer want, like hollow profile, its complicated section can greatly enhance the load ability. 5. environment-friendly Aluminum is one of the best metallic materials for recycling economy. The aluminum bridge does not corroded during usage period, has a great economic and social benefits. RE: Aluminum extrusion for bridge construction - ircasodle - 05-21-2018 Aluminium extrusions is highly rated in the present day’s sophisticated architecture. Load bearing structures , facades, claddings, windows, shop fronts, partitions, curtain walling, patent glazing, conservatories , glass houses, roofing scaffolding, architectural hardware , expansion joints , solar panel frames etc all use aluminium extrusions. Its qualities of aesthetic appeal, flexibility, minimal costs & durability has invited increase in demand. Our profiles made under stringent quality control and checks ensure trouble free powder coating, anodizing and fabrication.
