7075 Extruded Anodized Hollow Round Aluminum Tube for Structural Frames and Railings
7075 Anodized Extruded Round Aluminum Tube
This 7075 anodized extruded round aluminum tube is formed by hot extrusion into a hollow round profile and then finished with an anodized surface layer. The round hollow section keeps the wall uniform around the whole circumference, so the tube carries bending and torsional loads in a predictable way along its length. Because the profile is extruded instead of drawn, the outside diameter and the wall thickness remain consistent from one end to the other, which helps when several lengths are assembled into a single frame.
Material and Construction
The tube is made from 7075 aluminum alloy, a zinc bearing grade that develops high strength after suitable heat treatment, so it suits parts where stiffness and load capacity matter more than the lightest possible weight. The anodized finish forms an integral oxide layer on the surface rather than a coating that can peel away, and it raises resistance to everyday abrasion and to the moisture and salts that collect on outdoor equipment. Wall thickness, outside diameter and length are matched to the drawing or sample supplied for each order, and the hollow round section stays uniform along the full length so that cutting, drilling and tapping behave the same at any point.
Benefits
- High strength 7075 alloy for load bearing frames and supports.
- Anodized surface for improved wear and weather resistance.
- Uniform extruded round hollow profile with consistent wall thickness.
- Straight, dimensionally stable lengths that simplify assembly.
- Light weight compared with solid bar of the same outside diameter.
- Clean surface that accepts further machining, drilling and tapping.
Typical Uses
The tube is commonly chosen for structural frames, machine guards, railings and handrails, equipment handles, display fixtures, utility poles and general fabrication where a strong yet light round tube is required. It also works well where parts are exposed to the weather, such as outdoor frames, supports and trim, because the anodized skin resists dulling and surface marking better than bare aluminum. Parts that need slotting or end tapping can be supplied ready for in house secondary operations.
Ordering Notes
Tell us the alloy, temper, outside diameter, wall thickness, length and finish you need, and we will confirm the details before production. Sample lengths are available so that fit and finish can be checked before a full order is placed.
