Stay on schedule with custom piping and structural assemblies built to your exact tolerances. Backed by in-house 3D Revit MEP detailing, certified welders, and rapid-turnaround capabilities, we deliver uncompromising quality with exceptional speed and reliability.
Send Your SpecsTight timelines leave little room for delays. You need a fabrication shop that understands what’s at stake and can deliver the exact results it promises.
When project scopes change or production bottlenecks occur, Maplevale Fabrications keeps work on track with emergency rework, fast turnarounds for custom fittings, and competitive pricing. Our advanced in-house detailing and agile scheduling allow us to respond quickly to complex challenges, helping you avoid costly delays and protect your bottom line.
That same commitment extends to planned shutdowns and plant upgrades. We work with your team to pre-fabricate replacement piping, verify pressure and material specifications, and coordinate deliveries, so every component arrives ready when you need it.
We fabricate carbon steel, stainless steel, and aluminum components to meet compliance standards under:
Your time-sensitive projects get immediate priority. While other fabrication shops contend with multi-week backlogs, our flexible production scheduling allows us to execute rush jobs and critical reworks.
Expect straightforward, upfront pricing with zero hidden fees. We deliver accurate, competitive quotes aligned with your required specifications even as project scopes adapt.
Eliminate field fit-up errors before cutting begins. We use advanced technology to produce 3D Revit models, material takeoffs, and exact cut lists, so the fabricated components we ship match your specifications before fabrication begins.
Unlike other shops, we work with your field dimensions or sketches to develop proper fabrication drawings.
Maplevale is a signatory to UA Local 67 and UA Local 46, the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada.
Our manufacturing workflow follows the same documented process across our shop, with each stage tailored to your project requirements.
Send your drawings, component dimensions, material requirements, delivery location, and timeline. We’ll review the package and scope the fabrication work from there.
Accurate drawings help prevent costly mistakes before fabrication begins. Our in-house detailer produces 3D models, shop drawings, material takeoffs, and cut lists to coordinate connections, reduce material waste, and improve production efficiency.
We source approved raw materials for the job and maintain applicable material records and traceability documentation as required by the specification. We account for material grades, durability, and corrosion resistance.
Our high-precision fabrication processes include cutting and preparing pipe sections and structural steel to approved dimensions. Fit-up checks ensure strong joints and reduce errors before welding.
CWB-certified welders follow approved procedures that specify material, pressure, and inspection requirements to ensure compliance with applicable industry standards.
Every weld receives a visual inspection, with In-house radiographic and dye-penetrant testing available to detect subsurface flaws. Third-party inspection can be arranged for field welds where your specification requires it.
Where required, stainless-steel components are pickled and passivated. Carbon-steel components receive the specified preparation or finish before final inspection and shipment.
At the final stage of fabrication, components undergo a final quality assurance check and identification tagging before shipping via Maplevale’s flatbed, tri-axle stepdeck, or five-ton fleet, or for on-site installation through our mobile welding service.

Our oil and gas metal fabrication capabilities cover custom components for oil processing and industrial plants. Each request is reviewed against the relevant service and quality requirements.
Carbon steel and stainless steel pipe spools, custom fittings, and welded assemblies for plant piping. We review specifications for liquid and natural gas service, including systems designed to withstand high pressures.
Custom piping, supports, and fabricated parts for processing equipment connections, including around pumps, valves, and heat exchangers. Petrochemical fabrication scopes are assessed for material compatibility, corrosion, and applicable codes.
Custom steel frames, brackets, equipment supports, and structural builds for heavy equipment and machinery, built to approved dimensions, loading details, and connection requirements.
Replacement pipe sections, custom fittings, and essential components for oil and gas facilities, including connections near storage tanks. We work from available drawings or field measurements to support planned shutdowns and oil and gas operations.
Mobile welding services for on-site fit-up adjustments, modifications, and selected repairs for qualifying oil and gas projects. We confirm site location, safety requirements, and field scope before scheduling.
Backed by CWB, NSF/ANSI/CAN 61, TSSA, CA B51, ASME B31.1 and B31.3, and UA Local 67 credentials, Maplevale delivers the structural, mechanical, process, and piping fabrication for the oil and gas industry.
We review fabrication packages for processing plants, terminals, storage facilities, and other industrial sites serving the oil and gas industry. Our capabilities include custom piping, equipment connections, structural supports, and replacement components for maintenance, retrofits, and plant upgrades.
To help fabricated components withstand extreme conditions, including high operating pressures, heavy use, outdoor elements, and corrosive environments, we work to approved drawings, material specifications, and established welding procedures. Quality checks and inspections during the manufacturing process play a crucial role in upholding structural integrity and ensuring safety.
Yes. We assess time-sensitive replacements, rework, and selected field welding required for the oil and gas industry. Lead times depend on shop capacity, materials, site access, and testing requirements. Send your specifications and required date so we can discuss availability.
We aim to respond to urgent inquiries within 24 hours. Southern Ontario is our service area for mobile welding and field support. Please note that this is a response target, not a guaranteed on-site arrival or repair completion time. Responsive service availability depends on location, materials, safety requirements, and inspection needs.
Yes. Maplevale offers custom tank fabrication for the safe storage of liquids and hazardous materials. We review storage tank requirements individually, including material selection, capacity, coating specifications, and regulatory compliance.
No. Maplevale does not provide drilling, gas extraction, turnkey pipeline construction, or fabrication of offshore rigs and offshore platforms. Our focus is on custom piping and structural fabrication for oil and gas facilities; standalone components are reviewed on a case-by-case basis.
We can assess oil refinery and petrochemical fabrication requests involving custom pipe spools, supports, fittings, and equipment connections. Send us the drawings, materials, pressure class, and applicable codes so we can confirm whether the work fits our capabilities.
