Cumminsguy and Ringo,
There are several others, but, for price, service, items in stock, three warehouses across the country to expedite delivery, they (King Metals) are ALMOST the only one I use, unless I need something really special.
Nice looking gate for a new welder there xd.
Edit: BTW, we do lots of railings and gates per year, we seal weld all pickets. Used to only weld two sides. That saves time and is plenty strong and lets the moisture, which WILL collect from condensation, weep out. BUT, customers got upset at the rusty spots showing up on their railings. So, we started welding them all the way around. Doesn't happen often, but, it will allow the moisture to acculmulate to the point that when we get winter freezes, and we get lots of teen and lower temps here in the winter, the moisture in the pickets freezes and rounds out the square tube and even splits the seams. BUT, since it only happens to 1 in about 50 and takes about 5 years to gather enough moisture and is off warranty, I give the customer what they want for looks.
Have a Great Day, Brent
