STRUCTURAL fiberglass columns (2023)


Man, these structural fiberglass columns really dressed up the front of the pool house! The porch needed a little weight, and these double columns definitely gave it. These columns act as double duty. They support a sizeable load and add that touch of class. Ill post a link, but these columns are made by @turncraftcolumns6139 . I've installed several over the years, inside of homes as well as the outside. Being that they are fiberglass, they really hold up well to the elements.

This is not a sponsored video. These are the products that I have chosen for the best results possible for this particular project. But, if anyone would like to sponsor W.K.D. Construction to use their products...then by all means, contact me! If I use a certain product, it's for a good reason. I stand behind all of my work and the products I install.


Good morning, yeah, Keith Dykes.

Here with wkd construction we're, standing in front of the beautiful pool house that we've been working on.

And today we are going to install some turncraft structural fiberglass columns all right these columns are structural, which means they are load bearing.

You can actually set weight right on top of them, and they will structurally be sound and hold up.

So I'll, turn this around and I'll kind of give you a oversee of what we've been what we got going on here.

But inside my header I have solid blocking.

So it will withstand the weight of the column, which will actually we're going to do two of them we're going to have two that run down to there.

And then two more running down there as well.

But we set up here inside the pool house.

So I could paint them as you can see.

They are solid fiberglass they're, probably almost a half inch thick.

So they're, they're, pretty heavy, pretty heavy duty.

They can I don't know, exact pound rating.

They will hold, but it's, pretty substantial.

But I've got a coat of primer and two coats of Sherwin-Williams, super paint, exterior acrylic enamel.

Here we have the post base.

And the top cap, they're just plastic so they're, not they're, not structural by any means.

They just kind of sit there, but I also have primer and a couple coats of the Sherwin-Williams, super paint.

All right like I, said, we're going to have two columns here, two columns there.

So we set the laser up found Center exact center of the header and just lasered all the way across because we're on these caps and the bases.

They actually have a little I.

Guess, a center line with a mold so I'm going to use that and line up all my laser that way everything is straight, because we cannot actually we can't Plumb the column because they are tapered as well.

So so we're going to use these as a reference, Mark, Fine, Center and Laser up all right.

We got the laser set up.

You can't, really see it really well, any kind of you saw that laser right there on here.

A little dot there butter a little trick, if you can't see, it gets a little piece of white paper, and you can kind of faintly, see it and line it up all right foreign as a pitch on it.

So the water and water gets here will run off.

So if you just put your base on it, if you set the base directly onto the patio it's going to be on a skew to be crooked, so Brent took a flapper wheel on the grinder and actually found the Contour of the brick and ground and ground it all off and made it level that way each each base is going to sit pretty close.

I mean, it's, not going to be just dead, dick, but it's it's going to be really close like you see there, I mean, it's, it's within with intolerance, all right like I was saying you you can't, you can't set a conventional level on it because it's tapered so here's.

What we're going to do I've got my mold marks, which I know is Center I took this block.

These marks are the width of this I'm going to line it up on the hash marks.

And then this will be my Center.

Then I'll, go ahead and stick my laser in the plumb bob and it'll find my Center Mark.

There I'm going to find my Center mark up top.

Oops, all right.

We got all of the bases positioned where we want them Plumb bobbed up top.

We know, we're the center of the column is going to go.

So we are going to find the center of the top cap, we're actually going to use a piece of 2x10 up top and mount it, because it fits perfectly snug in there.

And our columns are nine.

We ordered nine foot columns, which are about nine foot one.

But our actual height is about nine foot, two, nine foot, two and a half.

So this will actually be used as a shim as well.

So we can use the nine foot columns without having to order 10 foot and cut off a foot.

So we took the string went from one end to the other.

The header made sure we didn't have to go up or down, which we did have to go up.

We had to raise it up about almost 3 8 of an inch.

And we got the Jack sitting there.

So we'll, go ahead and measure from our block to The Brick cut our column and install it 109 and an eight let's straight up fiberglass.

So don't be, uh, cutting it inside or nothing, I mean, like a Corvette.

So as far as measuring the column, I measured all of them off of the top, we kept the top as the constant.

So we just measure from the top to the bottom since we will have a little degree of variation, just because of the brick being up and down and such, but just measure from the top down shim it up here.

Stick it in in place and then slide them back down all right foreign on the bottom, fitting them, we'll, let off the pressure on the jack.

And then we can raise them up, and we will actually use some little L brackets just to hold these.

Uh, stiff, make sure these are good too foreign.

So being that these are so close together you want when you look, you want these to line up.

So just take a straight edge, foreign L, bracket, fasten it into the fiberglass and then tap on it on each corner.

Basically, sometimes you do all four corners that way it'll be nice and secure foreign let's, try again, foreign probably inch and a half inch or three quarter tapcons.

And we probably won't do both of them we'll just do one on the outside there in the brick.

If you don't have one of these Milwaukee boxes, the little tool organizer bolt organizer, whatever you want to call get your wad.

They work.


Thank you is that 18th? Huh? Yeah.


Just an eighth inch drill bit.

Man, it really that fiberglass really holds really well and I mean, once you put the tapcons in there, it doesn't, I mean, it's not going anywhere.

Anyway, anyhow, Hammer works better.

Not gonna do it wouldn't be prouded all right so I measured in three inches from each side.

I had a shorter screw.

But it didn't really work.

So I got a two and a half inch, grk, fastener, foreign little spackle in there and paint right over.

It also got a bumblebee.

All right.

We got it figured out just drill the big hole.

First like butter, take a step on back.

Oh, yeah.

They're gonna look nice.

Two more to go foreign.

Thank you.

All right, we're going to set the Specter laser up get it right on this Edge.

And then just follow it all the way down that way.

If you come outside, you look down the columns and they're gonna be straight I, don't know, if I set the size earlier, these are inch and a half L brackets I, put them on the corners that way you've got a lot more room for when the base goes over it'll cover.

So you put them here, it's really likely.

It may show so that's, why I just put them on the corner because there's a lot more dead space in there foreign that was it that's, how we installed some structural fiberglass columns here on the pool house.

So we're gonna get with it.

We've got some concrete forming to do get it poured that way.

This whole pool area will be complete.

But thanks for watching.


Are fiberglass columns structural? ›
