Defence, Security & Infrastructure
Engineered aluminum for durability, structural integrity and long service life
Defence, Security & Infrastructure Applications
Dajcor Aluminum supports defence, security, and infrastructure markets with custom aluminum extrusion solutions engineered for durability, structural integrity, and long-term performance.
Defence, security and infrastructure programmes are specified once and then supported for decades. Traceability, dimensional consistency and a supply chain that will still exist in ten years tend to matter as much as the part itself.
Common applications we support
Where our profiles typically end up in this market.
Protective enclosure systems
Sealed housings that protect controls and instrumentation in exposed locations.
Transportation infrastructure profiles
Structural and trim profiles for transportation infrastructure and roadside installations.
Structural framing systems
Load-bearing framing systems where deflection and fastening points are specified.
Industrial walkway systems
Walkway, platform and access profiles for industrial and infrastructure sites.
Equipment housings
Machined and fabricated housings that protect equipment from weather and impact.
Reinforcement components
Sections added to stiffen or reinforce existing structures and assemblies.
Specified once, supplied for years
These applications are usually structural and often exposed. Higher-strength 6000-series alloys such as 6061 and 6082 handle the loads, and anodizing gives a corrosion-resistant surface that is integral to the metal rather than a coating that can chip away at an edge.
Manufacturing in both Canada and the United States matters for programmes with domestic content or continuity-of-supply requirements. We are ISO 9001:2015 certified, and dimensional tolerances follow Aluminum Association standards, confirmed per profile during quoting rather than assumed.
Infrastructure hardware is specified once and resupplied for decades — consistency is the requirement.
Materials and finishes
Profiles for every industry we serve are extruded from 6000-series alloys and finished in-house. The right combination depends on the loads, the environment and how visible the part is.
- 6063 and 6060
- General-purpose and detailed sections with excellent surface quality — the usual choice where the part is seen.
- 6061 and 6082
- Higher-strength structural alloys for load-bearing and safety-critical sections.
- 6005 / 6005A and 6463
- Structural sections needing more strength than 6063, and bright architectural trim.
- Anodized finishes
- Clear satin and etched, electrolytic colour and chemically bright, up to 27 ft in length.
- Painted finishes
- Durable indoor and outdoor coatings with consistent colour matching across runs.
- Mechanical finishes
- Buffing, brushing and deburring where a specific surface texture is required.

Common questions
Answers to the questions that come up most often at the quoting stage.
Aluminum extrusion tolerances depend on several factors, including the size and complexity of the profile, wall thickness, alloy selection, and the circumscribing circle diameter (CCD) of the extrusion. Industry standard tolerances are typically based on guidelines published by the Aluminum Association, which define achievable dimensional accuracy for solid, hollow, and semi-hollow profiles.
With Dajcor’s 7", 8" and 9-inch extrusion presses, we are able to produce a wide range of aluminum profiles that meet standard Aluminum Association tolerances across many applications. During the design and quoting stage, our team reviews each profile to confirm achievable tolerances based on the specific geometry and manufacturing requirements.
Working collaboratively during the design phase helps ensure the extrusion profile is optimized for manufacturability while maintaining the dimensional precision required for the application.
Aluminum extrusions can be finished in a variety of ways to improve durability, corrosion resistance, and appearance.
Common finishing options include:
- Mill finish for applications where the natural aluminum surface is acceptable
- Anodizing for enhanced corrosion resistance and decorative finishes
- Powder coating for durable colored coatings
- Brushed or polished finishes for aesthetic applications
The appropriate finishing process depends on the application, environmental conditions, and performance requirements. Our team works with customers to determine the best finishing option for their extrusion profile.
Yes. In addition to aluminum extrusion, Dajcor offers a range of secondary operations to support complete component manufacturing.
These services may include precision machining, fabrication, cutting, drilling, and finishing processes such as anodizing or powder coating, depending on the requirements of the application.
Providing these value-added services allows customers to streamline their supply chain by sourcing fully finished components from a single manufacturing partner.
