GeilSpace 3/4″ × 36″ Heavy Duty Grey Metal Pipe

Size and fit align with standard NPT 3/4″ fittings, offering a robust 36-inch length for DIY shelving and industrial-style frames. The pipe features a sturdy steel construction with a protective paint layer that provides rust resistance when intact. This set includes four pipes, enabling ready-to-build kits for versatile wall-mounted or freestanding projects.
GeilSpace 1/2″ × 36″ Stainless Steel Pipe

Constructed from 304 stainless steel, this 1/2″ pipe offers corrosion resistance and a smooth industrial finish. It is designed to fit standard 1/2″ threaded fittings and comes as a two-piece set. Ideal for compact frames, low-profile furniture, or kitchen decor projects where rust resistance and a clean look matter.
GeilSpace 6 Pack 1/2″ × 36″ Grey Pipe

This six-pack provides multiple 1/2″ pipes for larger projects or multiple builds. The pipes are designed with a standard industrial finish and offer rust resistance when the paint layer remains intact. They are well-suited for versatile shelving, fixtures, or decorative frames that require repetition and symmetry.
GeilSpace 6 Pack 3/4″ × 36″ Black Pipe

Designed with a smaller outer diameter than standard 3/4″ piping, these black pipes are lightweight for easier handling while still offering reliable performance for decor-oriented shelving. They are compatible with NPT 3/4″ fittings but are not recommended for high-load clamps. The six-pack format supports larger or multi-rod projects with a uniform black finish for a cohesive look.
GeilSpace 1″ × 36″ Black Pipe

This 1″ pipe provides a substantial option for heavy-duty framing or bold industrial aesthetics. The length is 36 inches, and the pipes come in a black finish compatible with standard 1″ fittings. The set includes four pipes, supporting larger structures or prominent display shelving that benefits from a stronger profile.
GeilSpace 3 Inch Exhaust Pipe

Designed for larger diameter projects, this 3-inch exhaust pipe is stainless steel and 36 inches long. It provides a straight, polished surface suitable for sturdy frames and decorative installations where a wider pipe is required. It is rust-proof and built for longevity in industrial-style builds.
Buying Guide
Key purchase considerations for 36-inch steel pipes include diameter compatibility, material, finish, and intended load. Consider the following perspectives to pick the right option:
- Diameter and fittings: Ensure the pipe diameter matches your fittings (NPT standards are common). For furniture and decor, 1/2″ to 3/4″ pipes cover most easy-to-handle builds, while 1″ pipes offer a stronger, heavier look.
- Material and corrosion resistance: Stainless steel (304) resists rust and is suited for damp environments, while black or grey painted finishes balance aesthetics with durability for indoor decor.
- Length and set quantity: 36 inches is a standard length for shelving. Sets of multiple pipes simplify multi-shelf builds, symmetry, and alignment.
- Finish and maintenance: Painted or powder-coated finishes add rust protection, but inspect the protective layer to maintain corrosion resistance over time.
- Load-bearing considerations: For loaded shelves or frames, pair pipes with appropriate fittings and anchors. Heavier-diameter pipes (1″ and above) typically support more weight but require stronger brackets and wall anchors.
- Environment and usage: Stainless steel resists moisture and cleaners better than painted steel. For decorative pieces, the look may drive the choice (grey, black, or stainless).
- Compatibility across brands: While many pipes share standard dimensions, verify thread standards and fittings compatibility to avoid misfits during assembly.
