Frequently Asked Questions
Q: Can aluminum sheets be welded?
A: Yes, using TIG or MIG methods. Alloys 5052 and 6061 weld best.
Q: How thick should aluminum sheet be for roofing?
A: 0.7mm-1.2mm for residential, 1.5mm+ for commercial.
Q: Does aluminum sheet metal rust?
A: No, it forms a protective oxide layer instead of rusting.
Q: What’s the best alloy for outdoor use?
A: 5052 or 3003 with painted/anodized finish.
Q: Can aluminum be used for food contact?
A: Yes, alloys 1050, 3003, and 5052 are FDA-approved.

Is Aluminum Sheet Metal Better Than Steel Sheet Metal?
When comparing aluminum sheet metal to steel, the advantages of aluminum include:
Cost: While aluminum can be more expensive upfront, its long-term benefits often outweigh the cost.
Weight: Aluminum is about one-third the weight of steel, making it easier to handle.
Corrosion Resistance: Aluminum naturally resists rust, whereas steel needs additional coatings.
Workability: Aluminum is softer and easier to cut, bend, and weld than steel.
Durability: Aluminum lasts longer in outdoor and marine environments.
