Coping for ski box

if you don't use coping your box willl be shit. Take it from someone with 5 years of park crew under there belt. if you have access to a welder a metal coping is best. usually using 1/8th inch wall 1x1 stock. usually making the frame out of that stuff then cross singers of 1/4 1xwhat ever the width of the box you want to make and throw those in ever 16 inches or so. and then set that hpde in there so it is flush with the coping of the 1x1 because you welded those 1/4 stringers down what ever ever the thickness of your sheet was. quick abbreviated version...

Thx I've seen people glue coping on does that work pretty good?

nooo. Don't do that.

Your best bet is to drill and bolt them. See what you can find for steel and take that into account when building your box. You can leave an offset on the sides the height of the coping. If you don't want to do that or already have a box you can simply throw a 2x4 on each side, dropped down the height of your coping.

Make sure you get the height right. If it's high or low it changes the way everything will slide. Also boxes where it goes from one to the other suck. Your speed and the feel changes as you go from all metal to all topsheet.

Welding a feature is the best way to do it, but that's not realistic for most people. With some 2x4s, a little bit of ply, a miter saw and a drill you can build a pretty fucking rock solid box though.

If you absolutely can't find anything else you could use pvc, but imo that so of voids the point of buying the hdpe in the first place.

If you spent the money on that, worth it to have steel sides.

How thick is your topsheet? Make sure to counter sink your screws a bit. If you bought thin top sheet be careful. You need the head under the surface so you won't catch it, kill yourself, your ski edge, and rip up the top sheet. At the same time if you drill too deep, the screw/bolt won't have any material to grab and might rip through which probably won't harm anything, but it won't be holding down the topsheet.

Get some pvc i guess

I don't know how legit your box is but I'd say there's a good chance you don't need to ball out on steel coping.

Pros of steel:
-feels more like a real park feature
-stronger/more integral

Cons of steel:
-heavy af (if you plan on moving your box around a lot take this into account)
-much more expensive than alternatives (pvc)


I'd suggest just using pvc. You'll have an easier time securing it to the box, will spend less money, can move the box easier, and if the coping cracks or whatever you can just buy another 2$ pvc pipe.

Thx helps a lot

Also my hdpe sheet is half an inch thick so should I use half inch coping as well?

That's good to hear. You will have plenty of room to counter sink the screws/bolts. Use a counter sink or a bigger bit to give yourself a hole at the top that's slightly wider than the head and deep enough that when you sink it in, the head is slightly under the surface, so you dont catch it.

With half inch you have plenty of room to play.

use at least 1" coping. Some of the square framed boxes in parks have 1 inch round tube coping added on top. Most of the t boxes are 2" coping. It's up to you, what you like, what you can find.

If you can, throw some shade over your box or cover it when not in use in the summer. The sun will help warp your top sheet in the off season.
