There are different grades/psi strengths of rebar. They are usually marked with their psi rating. The higher grades seem to be more weldable.

I`m thinking i`ll start cuting a .25in longer so it will stick out a little and get more weld on it and weld on the inside.They are osha invoved, the are for a boiler co.I also build the safety cages and give all a coat of yellow paint.

Reebar is made from different types of steel, meaning you may have some that has higher carbon and could be hardenable but some may not. so if you have some with high carbon the heat from welding could be making it to hard and brittle. I would recomend using somthing else.

If you are building them where OSHA would be involved remember the rungs have to be 3/4" dia minimum. Are you poking the rungs thru the sidebars? What's breaking on them? One other thing, ladders 20' and higher need saftey cages on them...BobLast edited by aametalmaster; 02-12-2007, 02:32 PM.
