fabrication.
Short answer
- All cut edges rolled or capped
- Cage retained for structure on every cut-down
- Thermostatically controlled heating only
- Food-grade donor units available where needed
Scope a build
What we build
Six categories
Cut-downs and open tops
Full open-top conversions, half-height troughs, and partial cut-ins for ladles and augers. Cage retained, edges rolled, drain bung fitted. The most-requested job in the bay.
Manifolded banks
Two to six totes linked with a common header, isolation valves per unit and a single discharge. For dosing systems and anywhere you need buffer volume without a tank.
Heating and insulation
Reflective or closed-cell jackets, thermostatically controlled band heaters, and heat-traced discharge lines for product that gels below ambient.
Dip tubes and gauges
Bottom-draw dip tubes for pump suction, sight-glass gauges on the side rail, and float switches for level control. Retrofit to any standard 6-inch lid.
Stands and skids
Welded stands for gravity feed, forkliftable skids for multi-tote assemblies, and spill-containment bases. Rated and stamped with the load we tested to.
Cage-only builds
Shelving, parts racks, dunnage frames and planter structures. A cage with welded shelves takes 1,200 lb and costs a third of a bought rack.
Hard limits
Four things we will not fabricate
Stated plainly, because being talked into one of these is how people get hurt.
Pressure vessels
A composite IBC is an atmospheric vessel. Its bottle is blow-moulded with a variable wall and its cage is not a pressure retaining structure. No wall thickness, liner or bracing makes it safe to pressurise, and we will not quote it.
Vacuum service on an unrated bin
Pulling vacuum on an atmospheric vessel collapses it. If you need vacuum transfer you need a rated stainless bin, and we will quote you one of those instead.
Uncontrolled heating
A band heater without thermostatic control will soften HDPE and deform the bottle within a shift. We fit controllers, always, and we will not supply a heater without one.
Potable builds from non-food donors
If the finished item holds drinking water or touches edible produce, the donor tote must be food grade with a documented history. No exceptions, and no "it will be fine after a wash".
What to send us
- 01What the finished item has to do — the job, not the dimensions
- 02The liquid or material, and its temperature range
- 03How it gets moved: forklift, pallet jack, crane, or never
- 04Where it lives: indoors, outdoors, sanitary floor, jobsite
- 05Any clearance constraints at the destination
- 06Quantity — one-offs and runs of fifty are priced very differently
A description of the job beats a drawing. We have talked a lot of people out of expensive builds into cheaper ones that worked better.
Indicative pricing
What fabrication costs
Plus the donor tote, which is usually the cheap part. Quantity moves these substantially.
| Build | Labour + parts | Lead time |
|---|---|---|
| Open-top conversion, edges rolled | $95 – $165 | 5 – 8 days |
| Cut-down trough with drain | $120 – $210 | 5 – 8 days |
| Hatch cut-in with hinged cover | $140 – $240 | 7 – 10 days |
| Dip tube + sight gauge retrofit | $180 – $320 | 7 – 10 days |
| Two-tote manifold with isolation valves | $420 – $680 | 2 – 3 weeks |
| Six-tote manifolded bank on a skid | $1,900 – $3,400 | 3 – 4 weeks |
| Insulation jacket, reflective | $210 – $390 | 2 weeks |
| Band heater with controller | $340 – $620 | 2 – 3 weeks |
| Welded gravity stand, 2 totes | $380 – $640 | 2 weeks |
| Cage rack with three welded shelves | $160 – $280 | 1 week |
Questions
Fabrication questions
What can you fabricate from an IBC tote?
Open-top conversions, cut-down troughs and tubs, hatch cut-ins, multi-tote manifolds with isolation valves, dip tubes, sight gauges, insulation jackets, band heaters, welded stands and skids, and cage-only racks. What we will not build is anything that holds pressure — a composite IBC is an atmospheric vessel and modifying one into a pressure vessel is unsafe at any wall thickness.
Can you work to my drawing?
Yes. Send dimensions, the liquid, the temperature and how the finished item gets handled. If a drawing does not exist, a description of the job is usually better — we have talked a lot of people out of expensive builds into cheaper ones that work better.
Will a cut-down tote still be strong?
In the cage, yes — the cage carries the structural load and remains intact. We roll or cap every cut edge so nobody loses a forearm, and we leave enough bottle wall below the cut to retain shape. An uncaged cut-down tote, by contrast, is a floppy tub and we do not sell those.
What about heating and insulation?
Insulation jackets in reflective or closed-cell foam, and band heaters for viscous product. Band heaters on HDPE need thermostatic control and a wide band — a narrow uncontrolled heater will soften the wall and deform the bottle in one shift.
How long does fabrication take?
Two to four weeks depending on drawing complexity and material lead time. Simple cut-downs and hatch cut-ins are faster, often a week. Manifolded banks with valves and gauges take the full four.
Materials
What we can and cannot join
Fabrication on a composite IBC is constrained by what will bond to polyethylene, which is not much. Knowing the limits early saves a design iteration.
| Method | Works on HDPE? | Use for | Limits |
|---|---|---|---|
| Extrusion welding | Yes | Permanent joins, patches, baffles | Needs matched resin; skilled operation |
| Hot-air welding | Yes | Smaller joins, capping strips | Lower strength than extrusion |
| Mechanical fastening with bulkheads | Yes | Fittings, gauges, dip tubes | Gasket compound must match the product |
| Adhesive bonding | Barely | Non-structural trim only | Polyethylene is a very poor bonding surface |
| Solvent welding | No | — | HDPE is solvent resistant; this is why |
| Riveting through the wall | No | — | Creates a stress raiser and a leak path |
| Welding to the cage | Yes (steel) | Stands, shelves, skids, brackets | Remove the bottle first; blast and re-coat |
The practical consequence is that almost everything useful is either an extrusion weld on the plastic or steelwork on the cage. If a design depends on gluing something to polyethylene, it will fail, and it is better to find that out at the drawing stage.
Design review
The five questions we ask before quoting a build
These come up on every job, and having answers ready turns a two-week quote into a two-day one.
| Question | Why it matters | What a poor answer causes |
|---|---|---|
| What liquid or material, at what temperature? | Decides resin suitability, gasket compound and whether HDPE is right at all | A vessel that softens or permeates in service |
| Does it ever hold pressure or vacuum? | Composite IBCs are atmospheric vessels only | We decline the job — this is a hard limit |
| How is it moved, and how often? | Decides whether the cage stays, and the skid design | A build that cannot be lifted once it is full |
| Where does it live — indoors, outdoors, sanitary floor? | Decides donor grade, base type and UV protection | A unit that crazes in two seasons |
| Who operates it, and from what height? | Decides working height, edge treatment and access | An edge at forearm height with no capping |
Short answer
- Describe the job, not the dimensions
- No pressure vessels, no vacuum service, no exceptions
- Food-grade donor if anything edible is involved
- Every cut edge gets rolled or capped

A 48-inch load centre will lie to your forklift
Your 5,000 lb truck is rated at a 24-inch load centre. A filled tote puts the centre of mass twice that far out, and the derating is not subtle.

'Dose two chemicals into a line at a controlled rate with a day of buffer' tells us more than a dimensioned sketch, and usually leads somewhere cheaper than the thing you were about to specify.
