Round Steel Tube Connectors

Round steel tube connectors are used to mechanically connect, position, and assemble round steel tubes. Depending on the application, the connector can use a sleeve, clamp, bolt, or other mechanical connection structure.

The main purchasing value is the ability to assemble tube components with standardized connectors instead of relying entirely on complex site fabrication. Mechanical connections can also make later dismantling, adjustment, or maintenance more practical than permanently welded joints.

Typical applicable steel tube outside diameters range from approximately 20 to 114 mm. Other sizes can be customized according to the actual tube dimensions.

Connector bodies can be manufactured from carbon steel or stainless steel. Common fastener sizes range from M6 to M16. Surface treatment options include electro-galvanizing, hot-dip galvanizing, and coating.

Round steel tube connectors can be used in industrial equipment frames, pipe supports, machinery structures, guardrail systems, building MEP supports, warehouse facilities, and other structures assembled from round tubes.

For mechanical structures that need frequent installation or adjustment, a mechanical connection can avoid some of the limitations of a permanently welded assembly. In repetitive structures, consistent tube outside diameters and hole positions can also support more standardized installation.

However, round tubes may have different wall thicknesses, outside diameters, and load purposes. Connector clamping dimensions, material thickness, hole diameter, bolt size, and connection angle should therefore be determined according to the actual structural requirement.

This means the connector should be selected as part of the connection node rather than only by a general model number.

Zhuori Metal manufactures metal structures, building accessories, and hardware products and has processing stages including cutting, forming, welding, assembly, and inspection.

For round steel tube connectors, production can be organized according to customer-provided tube outside diameters, connection node drawings, and installation angles.

Connector thickness, hole diameter, hole spacing, bolt specification, and surface treatment can all be customized. The company has a team of around 40 people and R&D personnel who can work with buyers during the sample stage to confirm clamping and installation structures.

Once the dimensions are approved, the same confirmed requirements can be transferred into batch production.

OEM and ODM production is supported, including manufacturing from customer prototypes. For special connection angles or non-standard tube sizes, custom sample development normally takes about one week.

Small quantities of samples can be provided. Different tube diameters and connection forms can also be combined within one order.

Products undergo a full inspection before packing, and third-party inspection is accepted. For larger orders, pricing adjustments may be provided according to purchase quantity. Photo or video production updates can also be supplied.

Finished product can be packed on pallets, in cases, or with protective wrapping, helping separate different connector sizes and configurations during transportation and project delivery.
