I took a trip to Rose Steel today to look at their stock. The staff was very friendly and helpful, and their prices seemed very fair. I bought:
For bike frames:
- 24 feet of 16 gauge (1/16″) 1.5 inch square steel tubing
- 24 feet of 1/8″ thick 1.5 inch 6063 aluminum tubing
For wheel dropouts and misc load-bearing small parts:
- 4 feet of 2″ wide 1/8″ thick steel flat bar
They cut the tubes into 8 foot sections. Because Houston Metro is such a large area, driving to the place was a little bit of a hike. Within reason, I was trying to buy as much material as I’d need to tide me over for awhile. I figure this is enough metal to make at least two complete bike frames out of each material, but time will tell!
