Start with the pipe diameter

Pipe fit is the first purchasing check. Our scaffolding clamps are made for 32 mm, 48 mm, and 60 mm steel pipes, with customized dimensions available. Match the clamp size to the outside diameter of the tube used in your frame. A correct fit keeps the connection aligned and avoids ordering a clamp that cannot seat on the pipe.

For a greenhouse project, sort the pipe schedule before requesting a quotation. Separate the sizes used for the main skeleton, crossbars, side rails, irrigation lines, and support rods. Send those diameters with the required quantities so we can prepare the right clamp mix.

Match the clamp type to the joint

The joint function determines which scaffolding clamp suits the work. We supply four types for different connection tasks:

• Fixed scaffolding clamps make rigid, bolted connections between two steel pipes. They suit intersections between uprights and horizontal bars in a main greenhouse frame, where the joint needs to resist movement.
• Swivel scaffolding clamps are intended for quick installation and disassembly. Their snap-on structure suits temporary greenhouses, shading frames, emergency repairs, and lightweight mesh or film supports that may be repositioned.
• Internal clamps, also called Clamp In, sit inside aluminum channels or film-lock systems. Their embedded installation gives a flush appearance and suits greenhouse systems that retain film or shade material through internal tracks.
• Scaffolding single clamps hold one tube in place. They fit non-load-bearing components such as irrigation pipes, side rails, and support rods.

This distinction helps prevent a common purchasing error: using a single pipe clamp where two pipes must be joined, or using a quick-installation type for a rigid main-frame intersection. Select the fixed type for the main crossing connection, the swivel type for temporary or repositionable support, the internal type for a channel-based system, and the single type for one-tube fixing.

Consider the installation method

The range combines bolted, quick-snap, and embedded installation methods. Bolted fixed clamps are suited to connections that should remain rigid. Quick-snap swivel clamps support fast assembly and removal where the structure is temporary or the support position may change. Embedded internal clamps belong with compatible C-channel or film-lock tracks, so include a drawing or channel cross-section when ordering them.

Picture a tunnel greenhouse with steel uprights and horizontal bars. At each crossing, measure the pipe diameter and specify fixed clamps if the connection forms part of the main frame. If shade fabric will be changed seasonally, a swivel clamp can suit a lightweight support that needs quick repositioning. For a hydroponic layout, single clamps can hold irrigation pipes separately from the structural joints.

Check outdoor exposure and material

Our clamps use carbon steel with a galvanized coating. The finish is intended for outdoor greenhouse conditions, including rain, humidity, and UV exposure. This material choice suits commercial tunnel greenhouses, backyard hoop houses, Gothic arch greenhouses, hydroponic frames, and irrigation support structures covered by the product range.

Use the application to determine the required type and quantity. A humid greenhouse may need clamps across both structural and service runs, but the connection function still matters. Main-frame intersections call for the fixed configuration. Film, mesh, and temporary support work can use the swivel configuration. Internal channels call for Clamp In, while single pipes and non-load-bearing rods call for the single configuration.

Prepare a clear clamp schedule

A useful order schedule includes the pipe diameter, clamp type, connection purpose, installation method, and quantity. Add whether the joint belongs to the main frame, a temporary shade or film support, an internal track, an irrigation line, or a side rail. We also handle OEM and custom dimensions, so a drawing is useful when your tube profile or channel differs from the standard sizes.

For distributors, separate the four clamp types into stock groups by 32 mm, 48 mm, and 60 mm pipe size. That arrangement makes it easier to match a replacement or project kit to the installer’s pipe list without mixing fixed, swivel, internal, and single functions.

Questions to settle before ordering

Send the pipe list with your inquiry

For greenhouse frames and outdoor pipe supports, our scaffolding clamps fit best when the order separates diameter, joint function, and installation method. Send the pipe sizes, clamp types, quantities, frame or channel drawings, and intended use so we can match the configuration to your project.
