Steel Products and OEM Services for Heavy Equipment and Agricultural Manufacturers
Heavy equipment and agricultural machinery operate in the most punishing conditions in any industry – abrasive soils, heavy impact loads, extreme temperatures, and continuous duty cycles. Triad Metals supplies the abrasion-resistant plate, structural steel, HSS tubing, and processed OEM components that equipment manufacturers need to build machines that survive real-world field conditions. Our integrated supply model – from raw material sourcing through precision processing, kitting, and just-in-time delivery – keeps OEM production lines running without the supply chain disruptions that idle assembly teams.
AR400 and AR500 Abrasion Resistant Steel Plate
Abrasion-resistant (AR) steel plate is the material foundation for wear components in heavy equipment and agricultural machinery. AR400 and AR500 plate – quenched and tempered, high-hardness carbon steel – is engineered to resist abrasive wear, impact, and sliding contact in demanding applications.
AR500 steel provides a typical Brinell hardness of 477-534 BHN and is used where maximum wear life is the priority: excavator bucket liners, crusher liners, dump body liners, chute liners, hopper liners, and conveyor wear plates. AR400 steel (360-440 BHN) offers a balance of hardness and formability, making it the preferred choice for components that require both wear resistance and fabrication workability – equipment body panels, structural wear surfaces, moldboards, grader blades, and cutting edges.
Both grades can be processed in-house with plasma cutting, flame cutting, drilling, and beveling. For equipment OEMs, we process AR plate to your engineering drawings and deliver as cut parts ready for welding and assembly.
Structural Steel and HSS Tubing for Equipment Frames
Equipment frames, chassis rails, boom structures, and implement arms require structural steel with the strength-to-weight performance to handle dynamic loads in the field. Triad Metals stocks wide flange beams, channels, angles, flat bar, round bar, and plate in ASTM A36, A572 Grade 50, and A514 (T-1) grades for equipment frame construction.
Our HSS tubing inventory — including jumbo HSS up to 22 inches square — provides equipment designers with large-section hollow members for boom arms, frame cross-members, outrigger structures, and equipment housings where both torsional stiffness and weight efficiency are important. Square and rectangular HSS tubing is used extensively in agricultural trailer frames, implement carriers, combine frames, and material handling equipment structures.
OEM Parts and Custom Fabrication for Equipment Manufacturers
Triad Metals provides OEM steel fabrication services for heavy equipment and agricultural equipment manufacturers — cutting, drilling, and processing steel components to engineering drawings for direct integration into production assembly lines.
Our processing capabilities include tube laser cutting on two BLM LT8 tube lasers (handling tube diameters up to 8 inches) and one BLM LT24 (handling tube diameters up to 24 inches), plate plasma cutting, plate flame cutting, saw cutting, drilling and tapping, and beveling. Our plasma systems can also cut tube, providing additional flexibility for tube processing applications. For equipment OEMs, these capabilities mean complex tube profiles, precision plate components, and processed structural members can be sourced from a single steel supplier — eliminating the coordination overhead of managing separate material and fabrication vendors.
Whether you need laser-cut tube assemblies for boom structures, plasma-cut AR plate wear parts, or drilled and tapped base plates for equipment mounting systems, Triad Metals fabricates to your prints with the dimensional accuracy that OEM production demands.
Kitting and Just-in-Time Delivery for Equipment Production Lines
Triad Metals’ kitting program is purpose-built for equipment manufacturers that need all steel components for a specific assembly — pre-cut, labeled, and packaged together — delivered directly to the production line when the build schedule requires them.
Instead of maintaining raw steel inventory and running in-house cutting operations, equipment OEMs can offload material sourcing, processing, and staging to Triad Metals. Each kit contains every steel component for a defined assembly or sub-assembly, packaged and sequenced for the production team. This approach reduces floor space requirements, eliminates work-in-progress material handling, and ensures fabrication teams always have the right parts in the right quantities.
Combined with just-in-time (JIT) delivery scheduling, our kitting program gives equipment manufacturers the ability to scale production without proportionally scaling their material handling infrastructure. We deliver on your release schedule — weekly, biweekly, or on a production-triggered basis.
Frequently Asked Questions
What is the difference between AR400 and AR500 steel?
AR400 and AR500 are both abrasion-resistant, quenched and tempered steel plates, but they differ in hardness and application suitability. AR400 has a Brinell hardness of 360–440 BHN and offers a balance of wear resistance and formability — it can be bent, drilled, and welded more easily, making it ideal for equipment body panels, grader blades, and structural wear surfaces. AR500 has a Brinell hardness of 477–534 BHN and provides superior wear life in high-abrasion applications like bucket liners, crusher liners, and chute liners, but requires more careful fabrication practices.
Does Triad Metals offer kitting services for equipment manufacturers?
Yes. Triad Metals’ kitting program provides equipment OEMs with complete pre-cut steel component packages for specific assemblies or sub-assemblies. Each kit contains all steel parts — cut, drilled, and processed to engineering drawings — labeled and packaged together for direct delivery to the production line. Kitting eliminates raw material inventory management at the OEM facility, reduces handling steps, and ensures fabrication teams always have the correct components in the right quantities. We deliver kits on JIT schedules — weekly, biweekly, or production-triggered.
What tube laser cutting capability does Triad Metals have for equipment parts?
Triad Metals operates two BLM LT8 tube lasers and one BLM LT24 tube laser with capacity to process tube diameters up to 24 inches — one of the largest tube laser cutting capabilities among independent steel service centers. Our plasma systems can also cut tube, providing additional processing flexibility. The tube laser produces precision-cut tube profiles, coped joints, notches, holes, and complex geometries that would require multiple conventional operations. For equipment OEMs, tube laser parts come off the machine ready to weld, reducing assembly time and improving fit-up accuracy on boom structures, frame assemblies, and equipment housings.
Can Triad Metals supply steel for both heavy equipment and agricultural machinery?
Yes. Triad Metals serves both sectors from the same integrated supply platform. Heavy equipment manufacturers sourcing AR plate for wear components and structural steel for frames use the same processing and kitting capabilities as agricultural equipment manufacturers building trailers, implements, and grain handling machinery. Our product inventory includes AR400 and AR500 wear plate, structural shapes (beams, channels, angles), HSS tubing up to 22 inches square, flat bar, round bar, and plate in A36, A572, and A514 grades — covering the material requirements for both industries.
