The short answer
Yes, if the skid is going to be the platform your business runs on every day. A custom welded skid costs more up front than a $2,500 bolt-together skid off Facebook Marketplace, but it is built from roughly double the aluminum, it does not loosen up over years of road vibration, and ours carry a lifetime warranty. If you only need a rig for a few months of side work, the cheap skid may be all you need.
Most skid builders use 1/8" aluminum. We have always built with 1/4" aircraft-grade 5052. This article walks through exactly where that extra material goes and why it matters, using a bare skid straight out of fabrication so nothing is hidden behind a machine or a tank.
Watch: a bare EPW skid before anything goes on it
We rarely get to show a blank skid. As soon as one comes out of fabrication it goes straight to the build floor. This one gives you a clear look at the crossbars, gussets, under-shelf bracing and welds before a pressure washer, buffer tank, battery and reels cover them up.
If you want to jump around:
- 0:30 — 1/4" aluminum, welds and gussets
- 1:11 — Under-shelf bracing that holds the machine
- 1:57 — Welded vs. bolted skids: why bolts fail
- 3:45 — 1/4" vs. 1/8" aluminum: $2,500 skids compared
- 5:58 — Welded shelf frames vs. bent-sheet shelves
What a $2,500 skid is made of
Search Facebook Marketplace and you will find pressure washing skids for around $2,500. Most of them share the same recipe: 1/8" aluminum, bolted together instead of welded, and shelves made from a single sheet of aluminum with a bend folded into it for stiffness.
There are reasons that design is common. Thinner stock costs less. Bolts mean no fabricator is needed, and the skid can ship flat and be assembled in a driveway. For a long time 1/8" was simply the industry standard, and we saw it from nearly every builder.
None of this is a knock on the people building them. We have friends in the industry who build bolt-together skids, and there is a customer for that product. It is just not what we build, and the rest of this article explains why.
What an EPW skid is made of
Every EPW skid starts with 1/4" aircraft-grade 5052 aluminum, and it stays 1/4" everywhere: crossbars, shelves and bracing. That is roughly double the material of a 1/8" skid, and it is the single biggest difference between a skid that lasts a season and one that outlasts the truck it rides in. If you want the full breakdown of why 5052 aluminum beats steel, wood and poly for a skid, we covered that in Pressure Washing Skid Materials Compared.
Here is what is in the frame you see in the video:
- Full welds, not bolts. Every joint is a penetrating weld. Nothing on the frame is held together with a fastener that can back out.
- Gussets at every corner, top and bottom. The gussets you can see on the top rails are repeated underneath the shelves, where the real load lives.
- 1/4" square-tube bracing under every shelf. The shelf is not one bent sheet. It is a welded square-tube frame with a sheet on top, so the shelf itself is carrying the machine, the hot box and the battery, and the frame is carrying the shelf.
- Raised ends on the rails that stop a ladder from sliding off the skid.
- Forklift pockets built in, so the skid can be moved loaded without prying on the frame.
The shelf design took years to get right. If you look back at our older skids you can see it evolve, because the goal was never just a platform to set a machine on. The goal was a shelf that can hold a machine through years of road abuse without anything working loose.
Why welded beats bolted on a truck
Think about what sits on those shelves: an 8 GPM machine, a hot box or soft wash system, a battery, and two or three hose reels on the other side. Now put all of that in a truck bed that rattles over every pothole, speed bump and gravel driveway for years. Every bit of that shock has to go somewhere.
On a bolted skid, it goes into the bolts holding the shelves to the frame. We learned how bolts behave under that kind of abuse from the bolts that hold the machine itself to the shelf. Stainless bolts broke, so we moved up to Grade 8. We have seen a few of those snap too. If a handful of bolts are the only thing between a loaded shelf and the skid frame, every mile is working on them.
A welded 1/4" frame spreads that load through the whole structure. There is no fastener to work loose, no hole to elongate, and nothing to re-torque every spring. That is the whole reason we weld instead of bolt, and it is why we brace the shelves with square tube instead of relying on a bend in the sheet. A bend adds some stiffness. A welded tube frame under the sheet is a different category of strength.
The track record behind the lifetime warranty
We have never had an EPW skid weld break, and we have never had to warranty one. We have repaired plenty of other builders' skids that came through the shop cracked. We see fewer of those lately, which we take as a good sign for the industry.
Every EPW aluminum skid carries a lifetime warranty. If one ever does crack, we cover it. Local customers bring it to the shop in Oregon City. Customers anywhere else in the country get set up with a fabricator near them, and we take care of it.
Over the last couple of years, three or four builders have upgraded their materials and started building closer to the way we do. We are glad to see it. Even if a customer buys from one of them instead of us, that customer ends up with a skid that is far less likely to break, and that is good for everyone who runs a rig for a living.
The frame is the foundation, but it is only part of the recipe. The same approach carries through the rest of every build: Honda engines, upsized marine-grade wiring, 316 stainless hardware, Kuri Tec plumbing hose, and a block-mounted unloader so pump vibration is not shaking it apart. If you want to keep all of that running for the life of the skid, our rig maintenance guide covers it.
So, are custom skids actually worth it?
We will say it plainly: we are not the cheapest option, and we do not try to be. Here is how the two approaches stack up.
| $2,500 Marketplace skid | EPW custom skid | |
|---|---|---|
| Aluminum thickness | About 1/8" | 1/4" aircraft-grade 5052 |
| Construction | Bolted together | Fully welded, gusseted, double-braced |
| Shelves | One bent sheet | Welded 1/4" square-tube frame under the sheet |
| Under road vibration | Load goes into the bolts | Load spreads through the frame |
| Warranty | Varies | Lifetime on the aluminum skid |
| Best for | Part-time or light use | Daily use, heavy equipment, long hauls |
When the cheap skid is fine. You wash part-time or seasonally, you are running a smaller machine without a hot box, you rarely haul it far, or you can weld and would rather fix it yourself when something cracks.
When a custom skid is worth it. The rig goes out every day. You are running an 8 GPM machine with a hot box or a soft wash system. You drive real miles between jobs. You want the skid to outlast the truck and hold its resale value when you upgrade.
One honest drawback. We do not sell many empty skids. A welded 1/4" skid cannot be torn down to ship smaller, so freighting a bare frame across the country is expensive. Almost everything we ship nationwide is a fully built rig. Local customers pick up bare skids at the shop or order a custom size.
How to evaluate any skid, ours included. Ask the builder five questions: What thickness is the aluminum? Welded or bolted? How are the shelves built underneath? Where are the gussets and bracing? What does the warranty actually cover, and who does the repair? If the answers are quick and specific, you are talking to someone who has thought about it.
