Structural Pipe & Fittings make it easy to build strong, modular frameworks for guardrails, handrails, racks, greenhouses, workstations, displays, and light industrial layouts. This category covers structural pipe (often Schedule 40) and a wide range of fittings—tees, elbows, crosses, flanges, base plates, swivel joints, couplings, reducers, and end caps—engineered for load-bearing connections. Popular options include galvanized steel for corrosion resistance, aluminum for lighter weight, stainless steel for high durability, and black steel for interior projects.

A key advantage is fast, weld-free assembly. Slip-on, set-screw fittings (often known as Kee Klamp-style) clamp to the pipe’s outside diameter, so most builds need only an Allen key and a saw. You can reconfigure structures later without cutting off welded joints, reducing downtime and waste. For heavy-duty or permanent builds, threaded and weld-on fittings are available.

Selection tips:
- Match fittings to the pipe’s outside diameter; nominal pipe size (NPS) does not equal actual OD.
- Choose materials and finishes for the environment: hot-dip galvanized or stainless outdoors; powder-coated options for appearance and added protection.
- Check load ratings and standards (e.g., ASTM A53/A500) to suit spans, post spacing, and guardrail requirements.
- Use compatible anchors for base flanges on concrete or wood, and cap open ends to keep moisture out.

Installation is straightforward: cut square, deburr edges, seat pipe fully in the fitting, and torque set screws to spec. Isolate dissimilar metals with inserts or coatings to reduce galvanic corrosion, and apply anti-seize on stainless fasteners. Plan upright spacing (often 4–6 ft, project-dependent) to limit deflection and improve feel.

Maintenance is minimal: inspect connections periodically, re-tighten set screws, and touch up finishes near cut ends. Shop structural pipe and fittings here to build durable, reconfigurable structures with professional results—no welding, no special trades, just reliable components that help you design, assemble, and scale projects with confidence.
