Structural steel & skids
Cross-braced skid frames and multi-level platforms fabricated from raw stock in our own bays.
Why it matters
The base everything else is built on, engineered rather than adapted.
Expertise
Our own shop, our own steel
Spectrum designs and builds its own treatment equipment — DAF units, clarifiers, dewatering boxes, polymer skids and custom vessels — modeled in SolidWorks before steel is cut and wet-tested before it ships. Which is why build-to-spec here is a normal Tuesday rather than a special request.

Capability
What the shop can make
Steel, vessels, trailers, controls, chemical feed and finishing — all in the same building.
Vessels & tanks
Cone-bottom hoppers, separator vessels, clarifier bodies and filter boxes in steel or FRP.
Why it matters
Custom geometry for footprints and chemistries no catalog unit covers.
Trailer-mounted units
Complete treatment trains built onto heavy-haul chassis, with access stairs, handrails and controls.
Why it matters
Treatment that arrives on wheels instead of as a construction project.
Controls & instrumentation
Stainless control panels, explosion-proof stations, rigid conduit and installed instrumentation.
Why it matters
The unit arrives commissioned-ready rather than as a mechanical shell.
Chemical feed systems
Metering pump panels, injection loops, polymer blending skids and delivery cabinets.
Why it matters
Chemistry and hardware specified by the same building.
Coating & finishing
Surface preparation, priming and finish coating before anything leaves the yard.
Why it matters
Corrosion protection appropriate to the stream, applied under controlled conditions.
How a build runs
Duty, model, fabricate, test, commission
Five stages, and the modeling stage is the one that protects the schedule.
Define the duty
Flow, contaminant, permit limit, footprint and access. Where the chemistry is unsettled, the in-house lab runs bench work first.
Model it
Each unit is modeled in SolidWorks to confirm payload, axle loading and drainage performance before steel is cut.
ResultProblems found on a screen instead of in a fabrication bay.
Fabricate
Cutting, fitting, welding and assembly in our own bays, by our own crews.
Wet test
Units are wet-tested with media and hoses installed, and instrumentation verified, before they ship.
ResultArrives ready to run rather than ready to troubleshoot.
Commission on site
Spectrum technicians and process chemists set feed rates and tune the unit against real influent, and stay until the data holds.
Engineering first
Confirmed on a screen before it is cut in steel
Every dewatering box is modeled in SolidWorks to confirm payload, axle loading and drainage performance before fabrication starts. A box that is over on axle loading or short on drainage area is an expensive thing to discover after it is welded.
The same discipline applies to skids and vessels: structure, access and serviceability are resolved in the model, so the fabrication bay is executing a design rather than solving one.
The equipment range
Chemistry in the same building
The welders and the chemists work for the same company
This is the part competitors cannot easily copy. When a treatability study says the stream needs a different residence time or an extra stage, changing the equipment is an internal conversation rather than a change order with an OEM. Clients building to spec get direct access to the process chemists for bench testing and start-up support.
Inside the laboratoryFAQs
Why does having your own shop matter to me?
Three reasons: lead time is Spectrum’s to control rather than a supplier’s, build-to-spec is routine instead of exceptional, and the process chemists who specify the chemistry are in the same building as the welders. When a stream does not behave as expected, changing the equipment is an internal conversation.
What do you actually build?
DAF units, circular and lamella clarifiers, dewatering boxes and roll-off filters, Turbo Phase Separators, carbon trailers, polymer blending skids, oil–water separators, chemical feed systems, filter boxes and trailer-mounted treatment trains.
How long does a custom build take?
It depends on the unit, but pre-engineered sizes ship considerably faster than field-erected equipment, and SolidWorks modeling before cutting is what keeps the schedule honest. Send the duty and you will get a real date rather than an optimistic one.
Do I get access to the engineers during the build?
Yes. Clients building to spec get direct access to Spectrum’s process chemists for bench testing and start-up support — that access is part of the model, not an upsell.
