Re: Aluminum Specification

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Welding almost any aluminium is a problem in the shop and the field.
In addition, if its a canopy subject of any kind of wind induced
vibration the problem is greatly compounded, especially on a first
job.  Can you bolt instead and cover connections with 'architecture'?
