Bridge for ATV

   / Bridge for ATV #71  
i just have to wonder, being in a stream all the time and being damp isnt that lovely steel plate gona rust out in no time, i know around here if you put a steel sc 40 steel pipe in the ground near anything damp like a brook or swampy area that its rusted off in not too many years. its a nice bridge i just fear it may not last, but maybe your soil is alot different down there i dont know

We then put the base of the bridge together and raised it easily with the backhoe.

The bridge fits on top of the culvert!

Markct, The gully is a dry gully. The water only flows when there is a hard rain. The soil is sugar sand. Even so, I am going to seal or paint the metal before I cover it up.

There are more photos below in the members only "Meetings & Get togethers".

I know where you're coming from Mark. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Probably why all those cars that were flooded in the hurricanes are headed our way to have their title's cleaned up.

Everyone knows a car raised in Texas doesn't have the rust problem of those maintained up north. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Seriously. You're probably right. We shouldn't have done the bridge project.

well i understand now that it only flows when it rains hard so most of the time its dry anyhow, i didnt mean to be questioning your work harv, just a thing i wondered about, but like i said i wasnt sure cause i know you guys have alot different soil and climate down there. i just was wondering cause i know around here anything like that in a brook that flowed year round would be rusted away in a matter of a decade or two unless kept cleaned and painted very often, but i suppose alot of that is the salt runoff from our roads too that must realy be hard on that stuff, but down there you dont have that problem at all. i hope you didnt take my comments as negative since you said "your right we shouldnt have done the bridge project at all" cause thats definatly not the case, it came out great and i would love to make something like that over our brook someday, but i would need to design it a bit different so there wouldnt be so much steel down near the water since our brook is wet year round. but a very nice job indeed, looks incredible like every project you have ever posted harv, and cant wait to see what it looks like with the stone on it

I apologize Mark. I was completely out of line. I'll try not to let it happen again. There's no excuse for my behavior. /forums/images/graemlins/blush.gif

Now some good news. Don's bridge would survive on the coast with a couple of additional steps to guard against rust.

We pretty well welded up the ends of the pipe top rail and posts. Those would need to have quarter inch holes drilled for venting and drainage.

Then it would need to be hot dip galvanized. It's not as expensive as you'd think. I'd guess two hundred and fifty to four hundred dollars for all the pieces in the bridge.

One of the things that's good about Don's is it needs no welding done after placing. Welding's not what you want to have after galvanizing. It's bad for the weldor. And it's hard to replace the safety coating that hot dip galvanizing gives the welded area.

Then one would need to put on a coat of mineral spirits based Kilz primer to prep the galvanizing for paint.

If you do decide to do a bridge and corrosion is an issue consider galvanizing. The things you have to keep in mind is all tubing needs to have vent and drain holes. There's heat involved. And the last thing they want is trapped moisture causing an eruption in the galvanizing tank.

The other thing is to design the project so it's in manageable pieces and on site welding is kept to a minimum.

One of the good things about the galvanizing process is that rust isn't an issue. Minimal oil and grease is removed in the tanks and rust just goes away. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif So when you look at all the preparation you have to do for other coating methods the galvanizing is actually simpler and easier.

It's just ugly right out of the box. /forums/images/graemlins/frown.gif

Again I apologize for being such a jerk this morning.
