How to Choose the Right Equal Angle Bar: A Practical Guide
How to Choose the Right Equal Angle Bar: A Practical Guide
Equal angle bar is one of the most versatile structural sections — used in frames, اقواس, towers, racks and furniture. Yet buyers often pick the wrong material. This guide covers the three main families: carbon, stainless and aluminum.
Carbon Steel Angle (س235ب / س355ب)
The lowest-cost option. Q235B is for general fabrication; Q355B is for heavier loads and lighter weight structures. Both need paint or galvanizing outdoors. See our Q235B angle, Q355B angle و galvanized angle.
زاوية الفولاذ المقاوم للصدأ (304 / 316إل)
Stainless angle does not rust and has a bright finish. It is used in food equipment, architectural trim, coastal structures and chemical racks. 304 handles normal indoor and outdoor air; 316L is for chloride and splash zones. See our stainless angle range و 304 equal angle.
زاوية الألمنيوم (6061 / 6063)
Aluminum angle is one-third the weight of steel and needs no painting. 6063 T5 is the architectural / decorative choice; 6061 T6 is the structural / machinable choice. See our aluminum angle range و 6063 T5 angle.
| مادة | Cost | تآكل | Weight |
|---|---|---|---|
| كربون / galvanized | Low | Needs coating | Heavy |
| Stainless | عالي | Excellent | Heavy |
| الألومنيوم | Medium | Good (no painting) | Light |
