Veteran-owned · Engineering and fabrication under one roof
One team.
Total accountability.
Engineering, fabrication, and inspection all happen in our own shop, with our own crews. Nothing is brokered out, nothing is handed off, and every order is backed by the ownership that has run this floor for 35 years.
Engineered in-house
Our engineering team draws every part from your spec and the actual roof pitch, never adapted from a catalog dimension.
Priced by the shop floor
Estimating sits beside the crews who build the order, so quotes carry real lead times and freight planned in from day one.
One point of contact
A dedicated project contact from first drawing to final delivery, with the full shop and the owner standing behind the order.
“We don't ship close enough. We ship right.”
Mission-critical construction
Building a data center?
We fabricate the rooftop package.
Roof curbs, spring isolation curbs, and equipment covers, engineered to the building you are actually putting up and proven on live data center builds. Fully welded, pitch-corrected, sequenced to your program, inspection-ready on arrival.
Product Line
The full line, at a glance.
Ten product families, each one custom-fabricated to the actual building. Select a product to see specs and request a quote.
How an order works
STEP 01
Send the spec
Drawings, dimensions, gauge, roof pitch: whatever the project has. No site visit needed; design is spec-driven and remote.
STEP 02
Engineered quote
Our engineers and estimators price the job alongside the crew that will build it. Freight is planned into the number. No surprises later.
STEP 03
Built, inspected, shipped
Fully welded, inspected before it leaves the shop, sequenced to your program. It arrives inspection-ready, on the date the build depends on.
No site visit required. Design is spec-driven and remote. Material supplier, not a subcontractor: no prequal gate, no sub-tier paperwork.
